A Compact Asymmetric Coplanar Strip‐Fed Dual‐Band Antenna for 2.4/5.8 GHz Wlan Applications

Abstract

ABSTRACT An asymmetric coplanar strip (ACS)‐fed dual‐band antenna using loaded capacitance terminations for 2.4/5.8 GHz wireless local area network applications is studied numerically and verified experimentally. The proposed antenna consists of two meandered strip radiating elements, two loaded capacitance terminations, an asymmetric ground plane, a shunt inductor, and an ACS‐fed structure. Two resonance frequencies are controlled by adjusting the dimensions of the two meandered strip radiator elements and two loaded capacitance terminations. This antenna has small size of 17 × 12 mm 2 including the ground plane. Simulation and measurement results show that the proposed antenna can work at dual‐band frequencies and has omnidirectional radiation patterns. © 2013 Wiley Periodicals, Inc.
