A Novel Design of Square and Circular Ring Triple Band Microstrip Patch Antenna for Satellite Application

摘要

A novel design of square and circular ring triple band microstrip patch antenna is designed for satellite applications. The overall dimension of proposed antenna is (21×25mm2) and it consists of a defected ground structure. The antenna characteristics return loss, gain, group delay, VSWR, radiation pattern and radiation efficiency are discussed. Due to this shape of antenna, its provide triple band at resonating frequencies of 4.17 GHz, 7.48 GHz, 9.3GHz, with the respective impedance bandwidth 5.51%, 1.87% and 15.77% on FR4 substrate, with gain of 6.62 dBi, 4 dBi and 5.12 dBi. The proposed antenna is designed and simulated by HFSStool.
