|Abstract: ||A circularly microstrip antenna (CMSA) with its related geometry intended for 5850-7075
MHz Malaysia HAPS operating band are presented here. Construction are made into
three layers having layer three surface copper re-formed on a microwave laminate (εr =
2.2) and by varying its middle air gap spacing's height. At the same time, these copper
at layer three will be electrically and magnetically fed via a smaller circular copper sheet
(fed via coaxial cable and varied its x-y position at layer two) in between layer three and
layer one (ground plane). Apart from normal circular form, a total of one to four circular
split ring structures are placed per circular copper including all the parasitic elements
with CCSRRs relevant width dimension are studied to obtain bandwidth improvement
and higher gain. Using lower dielectric value microwave laminate and its corresponding
larger thickness has pull off more than 2.0 GHz bandwidth (VSWR < 2) marking 5850
MHz as the focal operating point.|
