Disediakan oleh: Hasrul Hafiz Abu Bakar, Mohd Aldrin Ali, Haslizamri Md Shariff, Mohd Izzat Mod Arifin, Fadhli Dzul Helmi Mohd Fauzi, Abdul Hafiz Kassim.



    Pada 23 Ogos 2017 bertempat di Sekolah Menengah Sains Dungun Terengganu telah berlangsung Program Misi Akademik “Menjuruterakan Anak-Anak Bangsa” anjuran Fakulti Kejuruteraan Elektrik UiTM Terengganu Kampus Dungun. 
    Misi akademik ini dijalankan untuk memupuk minat pelajar Tingkatan 4 dan 5 aliran sains bagi mendalami serta meminati bidang kejuruteraan elektrik. Justeru, misi ini akan mempromosikan Fakulti Kejuruteraan Elektrik UiTM agar menjadi pilihan pertama ketika mengisi borang kemasukan ke universiti kelak.Objektif program ini adalah untuk membantu pelajar dalam memahami dan menguasai subtopik Elektrik dan Elektronik bagi subjek Fizik. Selain itu, memberi pendedahan kepada pelajar sekolah tentang Fakulti Kejuruteraan Elektrik dan dengan ini dapat mempromosikan UiTM khususnya Kampus Dungun. Program ini juga dapat membina rangkaian dengan sekolah menengah aliran sains untuk kepentingan bersama seperti pertandingan inovasi. 
    Seramai 100 pelajar telah hadir bagi menjayakan program ini dan para pelajar menunjukkan minat yang mendalam setelah para pensyarah memberi taklimat serta motivasi bagi memupuk minat para pelajar didalam bidang kejuruteraan elektrik/elektronik. Majlis ini turut diserikan dengan kehadiran Pengetua SMSD iaitu Yg. Berbahagia Tuan Haji Aliziyad bin Abas dan turut diiringi oleh Penolong Kanan Puan Roslina bt Abdul Aziz. Tuan Pengetua sangat mengalu-alukan kedatangan pihak UiTM dimana telah termeterai memorandum persefahaman (MoU) sejak sekian alam antara UiTM dan SMSD. Tuan Pengetua juga mencadangkan program ini dijalankan secara timbal balik, dimana program seterusnya akan dilaksanakan di dalam kampus UiTM bagi mendedahkan para pelajar menengah atas tentang kehidupan serta pembelajaran di alam universiti. 
    Seterusnya, Encik Hasrul Hafiz bin Abu Bakar selaku Ketua Pusat Pengajian Fakulti Kejuruteraan Elektrik UiTM Terengganu telah merasmikan program Misi Akademik FKE-SMSD 2017 dan diteruskan dengan penyampaian cenderamata UITM kepada pihak pengurusan tertinggi SMSD. Encik Hasrul Hafiz juga memberi taklimat secara lengkap dan terperinci kepada pelajar SMSD tentang syarat kemasukan, program yang ditawarkan serta kelebihan yang ada di FKE UiTM. Tidak lupa juga, KPP memberi motivasi kepada pelajar tentang prospek kerjaya setelah bergelar seorang jurutera kelak. Seterusnya sesi soaljawab mendapat sambutan yang hangat dimana para pelajar banyak bertanyakan soalan tentang laluan kemasukan ke UiTM khususnya laluan untuk kemasukan ke diploma dan sehingga peringkat ijazah pertama/sarjana/phd. Encik Hasrul Hafiz mengingatkan para pelajar agar memenuhi syarat asas kemasukan agar pihak Unit Pusat Universiti (UPU) tidak menolak permohonan pelajar kelak. 
    Seterusnya bengkel Mathematical Thinking diteruskan dan disampaikan oleh En. Haslizamri. Bengkel ini berjaya menarik minat para pelajar untuk memahami ilmu matematik yang diperlukan oleh seorang jurutera kelak. Bengkel ini menekankan aspek penyelesaian masalah secara realisitik, rasional dan logik. Ia juga mampu meningkatkan keupayaan dan kemahiran pelajar berfikir aras tinggi. Program ini juga turut mendedahkan para pelajar tentang ilmu kejuruteraan elektrik dan elektronik. Para pelajar telah dipecahkan kepada 5 kumpulan (Latihan Dalam Kumpulan) dan diajar tentang asas elektrik dan elektronik mengikut silibus Fizik tingkatan 5. Seramai lima (5) orang fasilitator iaitu Encik Saiful Najib, Encik Fadhli Dzul Hilmi, Encik Muhd Azri Abdul Aziz, Encik Mohd Izzat dan Encik Hafiz Kassim telah membantu menjayakan slot LDK ini. Para fasilitator mengingatkan para pelajar supaya mengukuhkan asas kefahaman tentang subtopik ini bagi memudahkan mereka apabila memasuki alam universiti kelak. LDK ini telah membantu para pelajar meningkatkan kefahaman tentang subtopik elektrik dan elektronik dimana sebelum ini mereka kurang gemar untuk menjawab soalan elektif ini. 
    Diakhir program, pihak SMSD telah menyampaikan sijil penghargaan kepada fasilitator yang bertugas dan program ini telah tamat dengan jayanya pada jam 2 petang. Diharap program Misi Akademik ini menjadi pendorong untuk para pelajar meneruskan pengajian ke peringkat tertinggi seterusnya memilih UiTM sebagai pilihan utama mereka.

Radome Antenna

The advancement of technologies in antenna's world stimulates growing new demands to get better antenna performance on the design process for all components, including radome. Radar Dome, or usually called Radome is a dielectric material which is placed over the antenna for protection from its physical environment. In this case, the energy radiated by the antenna must pass through the radome. In most cases, some amount of radiated energy is dissipated as it passes through the antenna radome. This dissipated energy reduces the effective gain of the antenna and causes several effects, such as boresight error, changing antenna side lobe level and depolarisation. To achieve higher gains, dielectric radome with antennas as the source constitutes a relevant solution. The current technique used composite or layered materials like Teflon, Polyethylene and Quartz to suppress the reflection of the radiated energy but, it makes the fabrication more complicated and highly cost. Figure 1 shows the construction of patch antenna enclosed by a radome[1].

Even though the antenna may be carefully designed to have low sidelobes and high radiation efficiency, a poorly designed radome can degrade its performance seriously. Typically, the radomes are fabricated of a thickness of a dielectric material, wherein the thickness is one-half wavelength at a mid-band frequency of operation for the antenna. The composite or layered dielectric radomes are frequently required in practise to protect antenna systems against environmental conditions. However, the complicated manufacturing process inevitably introduces errors into the material properties of the composites, which tend to degrade the electromagnetic (EM) performance of radome. In conclusion, an optimum chosen material and construction design of radome are the key importance to focus through analytical technique to improve the antenna performance.

HISTORY OF CLINIC DAY for ELECTRIC CIRCUIT II (EEE231)

A program called “Clinic Day” is very synonym with a course that is prominent to have more than 25 percent of failures in final examination. For this Electric Circuit II, it also had been known as a “killer” subject or critical subject because of the high number of failures. 

 The first Clinic Day in this UiTMT was introduced by Dr. Mohd Zamri Jusoh in 2013 as a Lecturer in Charge (LiC) for this course. All students who had taken this course were compulsory to join this Clinic Day. The concept of this program is just like a study group, but each group is guided by mentors who are chosen by lecturer based on excellent result from tests. 

Also, during this Clinic Day they were specially consulted from lecturers who are taught in this course. The outcome result based on final examination from the first Clinic Day was really impressive.The failures percentage is totally below 25 percent for all programs (EE111, EE112 and EE113 programs). Hence, this Clinic Day is being catalyst for next LiC to carry on this super power program because the so called of killer subject is getting dull. Currently, it has been five series since the first it was presented. As an appreciation, the mentors are given a certificate and some of them also got honorarium.

Throughout these five series of Clinic Day, lectures who had involved as facilitator are Dr. Zamri, Ms. Suziana, Ms. Suziyani, Mdm. Nik NurShaadah, Mdm. Syazilawati, Mdm Nuraiza, Mr. Saiful Najib and Mr. Mohamad Taib. Many thanks to all facilitators who had supported the Clinic Day and spent their precious weekend time in helping students for more understandable about this course.Hence, it is hope that this Clinic Day will be continuously held for next semester.
