    • Analysis of the correlation between antenna gain and SAR Levels inside the human head model at 900MHz 

      Mohd Hafizuddin, Mat; Mohd. Fareq, Abd. Malek, Dr.; Ahmad, Omar; Muhammad Solihin, Zulkifli; Ronald, Suzanna Harun (Institute of Electrical and Electronics Engineers (IEEE), 2012-05-21)
      In this paper, the Specific Absorption Rate (SAR) inside the head due to metallic spectacle is investigated. Computer simulation using CST Microwave Studio is used in this investigation. A dipole antenna operated at 900MHz ...

    • A comparative study of simple geometrical head phantoms on specific absorption rates for simulations and measurements at 900MHz 

      Mohd Hafizuddin, Mat; Mohd Fareq, Abd Malek, Dr.; Ronald, Suzanna Harun; Zulkefli, M. S. (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
      In this paper, a dipole antenna operating at 900 MHz is simulated to examine the most suitable simple geometrical head phantoms for specific absorption rate (SAR) simulations and measurements. The numerical analysis was ...

    • Correlation analysis on the Specific Absorption Rate (SAR) between metallic spectacle and pins exposed from radiation sources 

      Mohd Hafizuddin, Mat; Mohd. Fareq, Abd. Malek, Dr.; Syed Idris, Syed Hassan, Prof. Dr.; Muhammad Solihin, Zulkifli; Ronald, Suzanna Harun (The Electromagnetics Academy, 2012-03-27)
      In this paper, the Specific Absorption Rate (SAR) inside the head due to metallic straight pins and spectacles is investigated. The finite integration in time domain technique (FIT) computer simulation using CST Microwave ...

    • Preliminary study of electromagnetic energy absorption in the head due to the exposure of radio frequency at 900MHz 

      Mohd Hafizuddin, Mat; Mohd. Fareq, Abd. Malek, Dr.; M. S., Zulkefli; Ronald, Suzanna Harun (Institute of Electrical and Electronics Engineers (IEEE), 2012-03-18)
      In this paper, the effects to Specific Absorption Rate (SAR) levels in human head proximity to metal-spectacle when using RF source investigated. The source is from a mobile communications enabled device (MCE) operating ...

    • Specific Absorption Rate (SAR) investigation on geometrical-shaped hand anatomically at GSM900/1800 

      Ronald, Suzanna Harun; Mohd Fareq, Abd Malek, Dr.; Muhammad Solihin, Zulkifli; Siti Fazlina, Maharimi; Mohd Hafizuddin, Mat (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      A right-handed heterogeneous geometrical-shaped hand model was introduced in this study with the size of Malaysian adult female to investigate different Specific Absorption Rate (SAR) value for different type of human hand ...

    • Study of Malaysian-sized hand phantom for GSM900/1800 application 

      Ronald, Suzanna Harun; Mohd Fareq, Abd Malek, Dr.; Mohd Hafizuddin, Mat; Zulkefli, M. S. (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
      A simple block hand model with the size of an adult Malaysian hand is suggested to substitute the existing hand phantom of European size. The hand is set up with a Standard Anthropomorphic Mannequin (SAM) head and a candy ...

    • A very small novel patch antenna design for WLAN application 

      Muhammad Solihin, Zulkifli; Mohd. Fareq, Abd. Malek, Dr.; Mohd Faizal, Jamlos, Dr.; Khairudi, Mohd Juni; Mohd Shaharom, Idris; Mohd Iskandar, Mohd Saleh; Mohd Hafizuddin, Mat; Ronald, Suzanna Harun (Institute of Electrical and Electronics Engineers (IEEE), 2012-03-05)
      In this paper, a very small 2.45 GHz printed antenna suitable for WLAN application is proposed. In order to decrease the size of the antenna, multi-layer substrate and shorting plate method are used. A microstrip line which ...
