摘要
In this manuscript, a new CPW-fed slot antenna with two band-notches for ultra-wideband communication systems is proposed. The antenna contains a trapezoid-shaped patch and a slotted ground plane. To achieve two notched bands, both of the inverted L-shaped strip and triangle-shaped element connecting to patch by a via are used. The designed antenna is printed on an FR4 substrate with compact size of 20x27 mm(2). Moreover, the antenna has been successfully fabricated and measured, indicating extended impedance bandwidth (3-11.2 GHz, VSWIR %26lt;= 2) and dual band-notched (3.2-3.9 GHz and 5-5.9 GHz), respectively.
