Circular Head-Shape Slotted Circularly Polarized Microstrip Antenna
Abstract
In this paper, one of the important parameter a is circular polarization. The design consists of square microstrip patch antenna using circular head-shape slot in second quadrant of the patch. Microstrip patch antenna is low profile, low cost antenna. A design of coaxial feed circular polarized, square shape microstrip antenna is presented and simulated by using CST 2010 and 4.4 relative permittivity law cost FR-4 (lossy) substrate are used. The antenna design of circular polarized frequency at 2.35 GHz with all size of 75 mm. Axial ratio, impendence bandwidth, and radiation pattern are presented and discussed. From the result is observed that the impendence bandwidth 34 MHz, axial ratio is 0.8 dB, gain 6.9 dB and –30 dB return loss.References (12)
