A compact dual-band monopole antenna for 4G LTE and WIFI utilizations

Abstract

In this paper presented a CPW-fed monopole antenna,which design for WiFi and 4G (LTE) utilizations. The proposed antenna contains a U- slot in the circular patch with gradually varied ground to improve the impedance match, and it occupies a compact size of 42*28.38*1.5mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> . Through simulations and measurements, the proposed antenna with dual-band operation is suitable to for 4G LTE and WiFi utilizations in the 2.28GHz to 2.82GHz band and 3.87GHz to 6.0GHz band.
