Abstract :
In this paper, a compact CPW-fed dual-band planar slot antenna with two embedded arc-like metal strips for multi-standard WLAN applications is presented. By protruding a pair of the arc-like metal strips from the ground plane into a circular slot, two resonant modes are excited at their resonant frequencies, which are lower than that of the circular slot. The experimental and simulated results show that the low-frequency band is determined by the total length of the protruding meandered strip and the operating frequency of the high-band is designed by the size of the circular slot. The prototype reveals the dual-frequency operation, indicating the frequency-ratio range from 2.14 to 2.71. Moreover, two resonant bands of the proposed antenna design show the broadside radiation patterns with the peak antenna gains of 1.5 dBi and 4.0 dBi, respectively.
