In this paper, a novel folded quarter-elliptical wideband monopole antenna for portable wireless applications has been presented. The proposed antenna has been fabricated and experimentally offers a wideband performance from 850MHz to 6GHz at 6dB return loss or VSWR 3:1. At this reference RL/VSWR level, the proposed antenna covers most of popular portable wireless frequency services including GSM,...
A coplanar waveguide (CPW)-fed planar monopole antenna with triple-band operation for WiMAX and WLAN applications is presented. The antenna, which occupies a small size of 25(L) ?? 25(W) ?? 0.8(H) mm3, is simply composed of a pentagonal radiating patch with two bent slots. By carefully selecting the positions and lengths of these slots, good dual stopband rejection characteristic of the antenna can...
