Abstract
This Paper has presented a new approach to design and simulation for Ku band. This proposed designed antenna is very useful for satellite communication. Coplanar capacitive coupled feeding technique was used to reduce probe inductance. This feeding technique is mutually coupled with this patch and feeding patch. This microstrip rectangular patch antenna has two dielectric substrates First substrate which is just below the patch is RT Duroid (e=3) and above the ground second dielectric is Air(e=1). Both dielectric materials has sandwich. So that bandwidth of the antenna. The resonating frequency of capacitive coupled double dielectric rectangular patch is 16GHz. Design and analysis of this rectangular patch antenna has been done in HFSS software. Bandwidth of simulated antenna is 4.5GHz. Return loss of this antenna is around-30dB.
