Miniaturization of ACS-fed dual-band antenna with loaded capacitance terminations for WLAN applications

Abstract

In this communication, we present the design of a compact, asymmetric coplanar strip (ACS)-fed, dual-band antenna for WLAN communication applications that is based on the use of loaded capacitance termination technique. The design procedure and the effects of the loaded capacitance terminations on the performance are described and investigated. The designed antenna has an electrically small size and its two resonance frequencies are realized by using two meander line monopole antennas with loaded capacitance terminations. The measurement results show that the antenna has impedance bandwidths of 168MHz and 187MHz, respectively, for operating frequencies of 2.4GHz and 5.8GHz.
