Abstract

In this paper, a compact asymmetric coplanar strip (ACS)-fed printed monopole dual-band antenna for 2.4 GHz bluetooth, 5.2/5.8 GHz wireless local area network (WLAN) and 3.5/5.5 GHz worldwide interoperability for microwave access (WiMAX) applications is presented and investigated experimentally. The proposed antenna is composed of a ACS-fed monopole, an arc-shaped strip and an omega-shaped strip, which occupies a compact size of 18 x 22 mm² including the ground plane. By properly selecting the positions and lengths of these strips, dual frequency operation with wide impedance bandwidth characterstics can be achieved. The proposed antenna has been validated experimentally and found to have nearly onmidirectional raiation patterns in the H-plane, nearly bi-directional behaviour in the E-plane and accepatable peak gain across operating bands.
