Initially, a single element circular tuning slot coupled Cylindrical Dielectric Resonator Antenna (CDRA) feeder is designed and fabricated for a symmetric parabolic reflector. Subsequently, the designed feeder is integrated at the focal point of the parabolic reflector to provide unidirectional radiation pattern with improved gain and sidelobe levels. The measured fractional impedance bandwidth achieved for the proposed antenna is 1.8 for S11<-10 dB from 5.32 to 5.52 GHz. A radiation pattern with broadside radiation and low back radiation has been obtained. A good measurement gain of approximately 13 dB is achieved over the bandwidth by placing CDRA feeder at the focal point of the parabolic reflector. In addition, a comprehensive parametric study has been conducted to realize the effect of slot size and position on the resonance frequency of the designed feeder. Furthermore, a parametric study of various reflector parameters has also been performed to study the effect of size, depth and focal point of the parabolic reflector on gain of the antenna. Important design factors have been identified from the parametric study of the antenna. The experimental and measured results show that the designed antenna is suitable for IEEE WLAN 802.11a wireless application. © Maxwell Scientific Organization, 2015. date: 2015 publisher: Maxwell Science Publications official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84938086856&doi=10.19026%2frjaset.10.2469&partnerID=40&md5=959336f4a38871b59991c8ba5815970f id_number: 10.19026/rjaset.10.2469 full_text_status: none publication: Research Journal of Applied Sciences, Engineering and Technology volume: 10 number: 6 pagerange: 607-617 refereed: TRUE issn: 20407459 citation: Ali, S.M. and Zakariya, M.A. and Baharudin, Z. and Adz, J.J. and Jilani, M.T. and Ain, M.F. and Ahmad, Z.A.
