Abstract

A microstrip patch antenna formed from Barium Strontium Titanate (BST) ceramics has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain and directivity of antennas with four, six and eight elements of BST array antenna and found that the gain of an eight elements of BST array antenna was enhanced by about 0.06 dBi of directivity and 0.2 dB of gain over the four elements of BST array antenna at 2.3 GHz. The impedance bandwidths of these BST array antennas for VSWR <; 2 were in the Worldwide interoperability for Microwave Access (WiMAX) application range which is 2.3 GHz to 2.45 GHz. Compared with the conventional array antenna with the same aperture size, the performance of the antenna is improved obviously and the design is suitable for array applications for example base station.
