Design of Reconfigurable Parasitic Antenna

The main objective of this book is to design an antenna resonating at 5 GHz frequency. An antenna is simulated with Taconic TLY 5 substrate and four parasitic elements with one main radiator and full of ground plane using CST Micro wave Studio Suite. It is also observed that the mutual coupling effect and parasitic element implementation contribute to the achievement of the beam-switching antenna at desired elevation angles (0, 3, 6 and 8) deg.; azimuth angles (11, 12, 150 and 14) deg. The reconfigurable beam-switching ability is developed using p-i-n diode switches. The maximum gain obtained during simulation is 7.160 dB and the maximum directivity is 7.191 dBi.
