Abstract

A double rectangular patch antenna with 4-bridges is investigated for use in IEEE 802.11b/g (2.4 GHz) and 802.11a (5.5 GHz) WLANs. A rectangular patch for the 5.5 GHz frequency band is printed on the PCB substrate and is connected by 4-bridges to another rectangular patch for the 2.4 GHz band to obtain dual band operation in one antenna element. The 4-bridges can modify the desired frequency band from its original frequency by changing their width. The proposed antenna has a low profile and is fed by a 50 Ω coaxial line. The gain of the 2.4 GHz patch is 5 dBi and of the 5.5 GHz patch is 3.7 dBi at θ=0°.
