Abstract

A design of a 2×3 ceramic microstrip patch array antenna with a 50 Ω microstrip transmission line feed is presented. The antenna was designed to operate at the Worldwide Interoperability for Microwave Access (WiMAX) application. The proposed ceramic which was Bismuth Titanate (BiT) was designed in rectangular form, with high dielectric constant of 21. Simulation using CST Microwave Studio has been carried out in order to verify this design. Due to high dielectric constant values, BiT elements on antenna had been tested as building blocks for miniaturized antenna solutions. The various dimensions of the BiT for both branching strips and radiating patches were investigated and found that different sizes of BiT lead to different resonant frequency. The simulation results were in good agreement with the desired frequency band of 2.3-2.5 GHz.
