“…With the same shunt inductive effect, the shorting pins are replaced by via holes to neglect the soldering step and reduce the tolerance between simulated and measured results [28]. Figure 4(b) illustrates a feed patch fabricated with 16 via holes on the Taconic TLY substrate with a thickness of 1.2 mm.…”

A compact and high gain resonant cavity antenna (RCA) is investigated in this work. At first, a ray-tracing model and the full-wave analysis are presented to clarify the characteristics of RCA in cases of finite lateral size and inhomogeneous superstrate. In consequence, a novel compact, high gain, and wideband RCA is proposed. The RCA consists of a via hole feed patch and an array of hybrid parasitic rings fabricated on a superstrate. The via holes feed patch with a high radiation directivity significantly enhances the RCA's gain. On another hand, the dimension and bandwidth of the RCA are improved by the hybrid parasitic ring superstrate which is constituted by non-periodic parasitic patch and rings. Finally, a prototype of the RCA is fabricated and measured. With only the dimension of 1.35λ 0 × 1.35λ 0 × 0.63λ 0 , the peak gain of 15.8 dBi and 3 dB gain bandwidth of 10.7% are obtained.
