- Abstract
- A two-arm microstrip spiral antenna with a circular aperture on the ground plane for multi-beam pattern control is presented. Several beam shapes can be selected by controlling the phase difference of the two spiral arms with the pin diode phase shifters located oil each feedline. At the operating frequency band the antenna has four different radiation patterns: the normal beam, the conical beam, and the two tilted beams. The multi-beam pattern control is confirmed with measurements.
