Abstract: In this dissertation, a novel design for dual-band dual polarized patch antenna operating at WLAN bands, 2.4 GHz and 5.2 GHz has been proposed. Initially, a dual-band antenna with linear polarization with two ports is designed. A corner fed square patch antenna operating at 5.2 GHz when feeding is done at one of the port, with an additional V-shaped patch is designed. Parameters of design are selected such that these two antennas acts as a single square patch when the feeding is done at the other port. Thus this antenna radiates at 2.4 GHz when feeding is done at one port, while it radiates at 5.2 GHz when feeding is done at another port. _ Next, CSRR structures to achieve high isolation between two ports of the antenna are designed. Isolation of better than -20 dB between two ports is achieved by incorporation of these structures in the design. To achieve circular polarized radiation, a rectangular slot in the square patch of the antenna is etched out. The corner fed square patch is made to radiate with circular polarization by the perturbation provided by this slot in the patch such that it provides 900 phase difference between two orthogonal linear components of electric field. This generates left-handed circular polarization at one port, while right-handed circular polarization at other port. The antenna parameters have been optimized using CST Microwave Studio and a Neltec NH9320 substrate of thickness 1.524 mm and relative perm
