ABSTRACT
A Microstrip Conformal Hexagonal Slot Patch Antenna fed by 50Ω microstrip line for various applications is presented in this paper. The strip loaded proposed antenna is fed through microstrip line to achieve proper impedance matching. Simulated results on High Frequency Structure Simulator software version 13 (HFSS 13) and CST10 are compared for FR4 – epoxiy substrate at different central angle of antenna. 1.6 mm thick substrate with 45º central angle provides best results of all the experimented angle. Maximum bandwidth of 2.2 GHz and return loss of -43 dB at resonant frequency of 13.5GHz is observed for the antenna. The antenna has been carved out from a cylindrical geometry and FR4 substrate with dimension 42*55*1.6 mm3 has been used. This antenna performs basically in C, X band and Ku band. Return loss and radiation pattern for this antenna is evaluated here. This antenna is used in communication and navigation technologies, aircraft, automobiles or ships, radar and satellite communication.
