Abstract

A novel CPW-fed slot antenna for Wireless Local Area Networks (WLAN) and World Interoperability for Microwave Access (WiMAX) applications is proposed, which can produce dual bands. Employing a CPW feedline terminated with a triangular split-ring res onator (SRR), good wide impedance matching can be achieved without an external matching circuit, and then wide bandwidths in the two working bands could be implemented conveniently. Measured results show that the proposed antenna can yield an impedance bandwidth of 1.96-4.33 and 5.05-7.23 GHz with reflection coefficient (SI 1) less than - 10 dB. In addition, the antenna has good radiation patterns in both E and H-planes. A comparison between measured and simulated results is demonstrated.
