Investigation on the CCSRR Influences towards CSMA with Air Gap for HAPS

A circular profile micro strip antenna and its related structural dimensions meant for 5850-7075 MHz Malaysia HAPS operating band are investigated here. Appearing by three layers and having layer three surface copper re-shaped on a microwave laminate. It was by varying the middle air gap spacing´s height covering layer two regions. At the same time, this conditions will permit copper at layer three to be electrically and magnetically fed via a smaller circular copper sheet (fed via coaxial cable and varied its x-y position at layer one) in between layer one and layer three (ground plane). Apart from normal circular form, a total of one to four complementary circular split ring resonators structures a replaced per circular copper including all the cascading parasitic elements with CCSRRs relevant width dimension are studied to obtain return loss improvement and higher gain.
