    • Microwave wedge absorber design using rice husk - An evaluation on placement variation 

      Nornikman, Hassan; Soh, Ping Jack; Fareq, Malek, Dr.; Azremi, Abdullah Al Hadi; Wee, Fwen Hoon; R. Badlishah, Ahmad, Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2010-04-12)
      Placement variation is one example of parameters that critically affects the performance of RF absorbers. In this work, four designed variation patterns - W, X, Y, and Z were discussed to compare the reflectivity (Sll) ...
    • Multiband fractal planar inverted F antenna (F-PIFA) for mobile phone application 

      Saidatul Norlyana, Azemi; Azremi, Abdullah Al Hadi; R. Badlishah, Ahmad, Prof. Madya Dr.; Soh, Ping Jack; Fareq, Malek, Dr. (EMW Publishing, 2009)
      The design of a novel Fractal planar inverted F antenna (F-PIFA) based on the self affinity property is presented in this paper. The procedure for designing a Fractal Planar Inverted F Antenna is explained and three different ...
    • Review and modeling of vegetation propagation model for wireless sensor networks using OMNeT++ 

      Munirah L., Kamarudin; R. Badlishah, Ahmad, Dr.; Ong, Bi Lynn; Fareq, Malek, Dr.; A., Zakaria; Mohd Arif, M. A. (Institute of Electrical and Electronics Engineers (IEEE), 2010-09-22)
      In simulation environments, prediction of path losses, maximum communication coverage for each node and received signal strength are calculated by using propagation model. However, most of the simulation tools only offer ...
