Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents the enhancement of bandwidth of a single-layer dual-band wideband multi-ring microstrip antenna (MSA) fed by an L-probe with outer separated elements. The proposed antenna consists of two outer separated ring patches, an inner ring patch, and a feeding L-probe arranged on a single-layer dielectric substrate. A thick dielectric substrate with a relative dielectric constant of 2.6 and a thickness of 3.2 mm is used for wideband operation. In order to obtain dual-band and wideband performance with the two central frequency ratio of 1:1.39, the structural parameters of the proposed MSA are optimized by using the electromagnetic simulator ANSYS HFSS. The simulated results reveal that two frequency ranges with less than 10 dB reflection coefficient (S11) are from 8.48 GHz to 10.38 GHz and from 11.94 GHz to 14.34 GHz and that the corresponding fractional bandwidths are 20.1% around 9.5 GHz and 18.3% around 13 GHz, respectively.
