摘要：
A broadband CPW-fed semicircular slot antenna is proposed for 2-6 GHz WLAN (wireless local area networks) and microwave imaging applications. The total dimension of the bidirectional slot antenna is 80 nun by 50 nun and is designed on a 0.5-mm-thick Duroid 5880 substrate (dielectric constant = 2.2). The antenna operates from 2 to 6 GHz within VSWR of 2.5:1. The same antenna on a combination rectangular cylindrical cavity with cavity depth of 10 mm provides a directional beam, 11 dB front-to-back (FIB) ratio and a bandwidth of 63% (2.8 - 5.4 GHz).
