摘要：
A modified microstrip-fed planar monopole antenna with an open-circuited coupled line is presented in this paper. The operational bandwidth of the proposed antenna covers the 2.4-GHz ISM hand (2.42-2.48 GHz) and the 5-GHz WLAN band (5- 6 GHz). The radiating elements occupy a small area of 23 X 8 mm(2). The finite-difference time-domain (FDTD) method is used to predict the input impedance of the antenna. The calculated return loss shows very good agreement with the measured data. Reasonable antenna gain is observed across the operating band. The measured radiation patterns are similar to those of a simple monopole antenna. (c) 2006 Wiley Periodicals, Inc.
