## Abstract In this paper, a design of a rectangular‐ring slot antenna for obtaining triple‐frequency operation using a coplanar waveguide (CPW) feed or microstrip‐line feed is presented. We introduce three concentric rectangular‐ring slots whose perimeters easily control the three respective opera

## Abstract This Letter describes a U‐shaped aperture‐coupled U‐slot triangular patch antenna fed by microstrip feed line. Because a thick aperture substrate with a dual U‐slot patch radiator are used in the design, a high level of coupling to the feed line results. The measured bandwidth of approx
Collected f 0 results are shown in Figure 15. The center frequency varies with s/(s ϩ w g ) ratio around the theoretical value c 0 /(4h g ) ϭ 1 GHz. However, it is noted that as the period length decreases (that is, (s ϩ w g )/ G decreases), f 0 depends less on the s/(s ϩ w g ) ratio. The dependence
