| Abstract | ||
| In the present work, design of circularly polarized microstrip patch antenna is presented in S-band of centre frequency 2.29 GHz. This microstrip patch antenna is considered to be the basic element of an array consisting of eight microstrip patches distributed and mounted on eight surfaces of cylindrical structure of octagonal shape. The field of radiation pattern of the antenna array is calculated for E and H-planes and it seems to be an omnidirectional pattern. A 90°-hybrid feed for each element is designed to excite the antenna with circular polarization within suitable matching for patch antenna and the hybrid. | ||
