    • Comparison of Direct Contact Feeding methods for a Rectangular Microstrip Patch Antenna 

      Soh, Ping Jack; Azremi, Abdullah Al Hadi; Anuar, Mat Safar; A. Nurainunnazli (Universiti Malaysia Perlis, 2007)
      Microstrip patch antennas have a variety of feeding technique applicable to them. It can be categorized in accordance to the main power transfer mechanism from the feed line to the patch. Contactingfeeds investigated in ...

    • A dual band planar monopole antenna with inverted-M parasitic plane 

      Nurul, H. M R; Soh, Ping Jack; Azremi, Abdullah Al Hadi; Ibrahim, M.I.; R. Badlishah, Ahmad (Institute of Electrical and Electronics Engineering (IEEE), 2007)
      Introduction of parasitic plane as additional radiator helps to produce desired resonant frequencies, while helping to minimize the size of the antenna. A dual-band monopole antenna with parasitic plane is designed to ...

    • Dual frequency integrated antenna (DFIA) with image rejection 

      Widad, Ismail; Sohiful Anuar, Zainol Murad (Institute of Electrical and Electronics Engineers (IEEE), 2005)
      A new configuration of integrated antenna featuring dual frequency operations and image frequency rejection is implemented. The used of dual frequency for image rejection in one system by using one antenna is a new technique ...

    • The effect of conductor line to meander line antenna design 

      Misman, D.; Salamat, I.A.; Abdul Kadir, M.F.; Che Rose, M.R.; Mohd Shah, M. S R; Abd Aziz, M.Z.A.; Husain, M.N.; Soh, Ping Jack (Institute of Electrical and Electronics Engineering (IEEE), 2008)
      In this paper, the meander line antenna (MLA) have been designed to operate at 2.4-GHz for WLAN application. Two different designs of meander line antenna are investigated, without conductor line and with conductor line. ...

    • Novel compact "via-less" ultra-wide band filter utilizing capacitive microstrip patch 

      Mohammad Shahrazel, Razalli; Alyani, Ismail; Mohamed Adzir, Mahdi; Mohd Nizar, Hamidon (EMW Publishing, 2009)
      This paper presents a novel compact "via-less" UWB filter derived from a quarter-wavelength short-circuited stubs model. In this compact "via-less" UWB filter, there is no connecting vias as short circuit elements. Unlike ...

    • Performance analysis and prediction using circuit model in a microstrip patch array 

      Soh, Ping Jack; Azremi, Abdullah Al Hadi; Dayang Khadijah, Hamzah; Raha, Abdul Rahim; Mohd Taufik, Jusoh; Junita, Mohd Nordin; R. Badlishah, Ahmad (Institute of Electrical and Electronics Engineering (IEEE), 2007)
      This work is an effort in investigating and modeling an accurate Circuit Model derived from the Transmission Line Method (CM/TLM) by simulating a rectangular microstrip patch array using two different simulation techniques, ...

    • Small antenna efficiency by the reverberation chamber and the Wheeler Cap methods 

      Azremi, Abdullah Al Hadi; Ghafouri Shiraz, H.; Hall, Peter S. (Institute of Electrical and Electronics Engineering (IEEE), 2005)
      Two methods of determining an antenna's efficiency are compared. Each of these methods was used to measure the efficiency of three different antennas (two monopole antennas with attenuator and surface mount resistor, and ...

    • Small rectangular parasitic plane as patch antenna ground plane for broadband WLAN application 

      Norra Shiella, Razali; Azremi, Abdullah Al Hadi; Soh, Ping Jack; Saidatul Norlyana, Azemi; Ibrahim, M.I. (Institute of Electrical and Electronics Engineering (IEEE), 2007)
      This paper proposed a microstrip patch antenna for broadband WLAN application. The antenna is based on an octagonal patch, which is simulated and analyzed by using Microwave Office (MWO) for WLAN applications. The designed ...

    • "Via-Less” UWB Filter using Patched Microstrip Stubs 

      Mohammad Shahrazel, Razalli; Alyani, Ismail; Mohamed Adzir, Mahdi; Mohd Nizar, Hamidon (VSP (imprint of Brill), 2009)
      This paper presents an Ultra-Wide Band (UWB) microstrip filter which is initially modeled from a quarter-wavelength short-circuited stubs, without the use of any vias. All vias that provide short circuit stubs are replaced ...
