It describes the development of antenna patches in microtrip with circular radiating elements defined in polar coordinates and catacaustic slots, which present multiband responses for application in wireless communications: cell phone communication, Wi-Fi and WiMAX. Inspired by the optical principle of caustic curves generated by reflection in the circumference, the catacaustic slots were introduced in patch antennas with these formats to tune their resonant properties. The proposed patch antennas were powered by microtrip lines with quarter-wave transformers for impedance adjustments. The antennas were designed with their irradiation and resonant properties analyzed precisely using the commercial software ANSYS Designer™. The experimental characterization of prototypes manufactured from patch antennas was carried out using a vector network analyzer. The agreement obtained between the simulated and measured results validated the adopted methodology and proved the frequency tuning property for multiband patch antennas studied.
