By analyzing and simulating the dual-frequency antenna based on CPW CRLH TLs, it was found that the antenna could be reduced further in size. By designing such resonant antennas with CPW technology, a great deal of design freedom is provided in relation to the shunt parameters in the equivalent-circuit model. This novel antenna design can help reduce the size of different wireless products, including those normally requiring separate antennas—such as products with PCS and WLAN capabilities.
