Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents improved design of a dual-polarized single-layer wideband ring microstrip antenna (MSA) fed by two L-probes with a via at the center of the radiation element. The proposed antenna consists of a square ring patch as a radiation element and two L-probes to excite two orthogonal modes of the patch. They are arranged on a thick single-layer dielectric substrate. In order to improve the port-to-port isolation characteristics, a via is introduced at the center of the ring patch. A thick dielectric substrate with a relative dielectric constant of 2.6 and a thickness of 3 mm is used to obtain wideband characteristics. The dimensions of the ring patch are tuned appropriately using the electromagnetic simulator ANYSYS HFSS. The simulated results reveal that broadband performance of a fractional bandwidth of 33.1% is obtained at around 12 GHz. Then, a prototype antenna is fabricated. The measured S11 and S22 less than -10 dB are from 10.32 to 14.32 GHz and from 10.72 to 14.64 GHz, respectively. The corresponding fractional bandwidths are 32.5% and 30.9%, respectively. The measured port-to-port isolation in the above bandwidths are more than 14.3 dB. Furthermore, reflection and port-to-port isolation characteristics of the proposed antenna with and without the via and with the ring and square patches are compared by the simulation.
