A novel dual‐band patch antenna for Zigbee system

In this article, a novel dual-band patch antenna having a chair-shaped slot is designed, fabricated, and measured for Zigbee system. The proposed antenna is designed to operate from 868 to 928 MHz (lower-frequency band) and 2.45 GHz (upper-frequency band). The lower-frequency band (868–928 MHz) can be controlled by adjusting the length of a chair-shaped slot and the upper-frequency band (2.45 GHz) can be controlled by the size of the rectangular patch. Details of the proposed antenna design and the measured results are presented and discussed. © 2007 Wiley Periodicals, Inc.
