In this paper is to give a conductor backed asymmetric coplanar inverted Lstrip fed antenna for dual band applications. The antenna exhibit resonance at 1. 8GHz (1. 6-1. 85GHz) and 5. 2GHz (5. 08-5. 35GHz) with impedance band width of about 150MHz and 200MHz (return loss>-10dB) which is used for DCS/GSM, Wi-Fi/WLAN applications. The antenna has an overall dimension of 19x21 mm2 when printed on a substrate of dielectric constant 4. 4. The planar design, simple feeding technique and compactness make it easy for the integration of the antenna into circuit boards.
