Abstract

The design of cavity-backed linearly-polarized cylindrical microstrip antennas is the focus of the present work. Probe-fed hybrid patches are considered in order to synthesize radiators with low cross polarization. Initially, the resonant cavity method, valid for electrically thin antennas, is used with the aim of establishing the antenna pre-design dimensions. Then, the commercial software HFSS is utilized for their optimization. Since hybrid patches require two of their sides connected to ground, SIW technology (Integrated Waveguide Substrate) is used to manufacture a prototype in the ISM band. Besides single antennas, circumferential arrays are also analyzed.
