| Abstract: | This paper presents a simple dual band-notched circular disc monopole(CDM) ultra-wideband antenna with CPW-feed and the ground plane consists of two semiellipses,thus achieving the ultra-wideband antenna and miniaturization.By cutting two U-shaped slots on the feed line and patch,two notched bands of 650 MHz and 590 GHz are achieved.The measurement result of physical antennas show that with the standing wave ratio(VSWR) < 2 the bandwidth is 2.97 GHz to 12.75 GHz and the antenna gain is high within the frequ... |
