The CCSRR influences towards circular microstrip antenna

Abstract

A circular profile microstrip 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 are placed per circular copper including all the cascading parasitic elements with CCSRRs relevant width dimension are studied to obtain return loss improvement and higher gain.

Triangular and tapered tip effects towards circular split ring EM field response

“…With TaT addition, the simulated electrical field are more confine and more responsive. Making it a better candidate, as it can concentrate the field components into a small area, escalating the volumetric sensitivity of the device [13,14].…”

“…Hence generating resonating currents in the split loop and produces equivalent magnetic dipole moment [11,12]. Causing this conventional CSRRs to behave as parallel LC resonating structure [13,14].…”

“…In other words, with this split ring triangular tipshaped combination. A new thin-film device that is more sensitive, reduced overall component size and able to retain its resonance frequency with better Q-factor [14] is introduced.…”

“…2, it displays the direction of the incident wave moving inside the WR159 waveguide. The simulations was carried out using tetrahedral mesh type frequency domain solver [12][13][14]. Moreover, the boundary conditions (see Fig.…”
