Joseph M. Mom, Atser A. Roy, Douglas T. Kureve . Investigation of the Effect of Feed Variation on the Performance of a Circular Patch Microstrip Antenna. International Journal of Applied Information Systems. 6, 5 ( November 2013), 1-4. DOI=10.5120/ijais13-451054
Abstract
In the design of circular patch antenna, the feed point locations SF=5, SF=6, SF=7 and SF=8 were selected and the simulated results compared and the optimum location adopted and implemented. The best feed point was located at SF=5mm where return loss RL is -37. 81dB, followed by SF=6mm with return loss RL of -17. 14dB and SF=7mm with return loss RL is -11. 38dB. The feed point location at SF=8mm was rejected since it falls outside the acceptable figure of VSWR=2. The material used for the proposed antenna is FR-4 with the dielectric constant of 4. 35 and dielectric loss tangent of 14e-3. The proposed antenna can find application in Wireless Local Area Network (WLAN) and cellular phone.
