  • The paper proposes a new design for a single-arm, rectangular, spiral antenna (SARSA) with a wide azimuth space coverage. The antenna, operating at around 3.3 GHz, is capable of steering the beam in four separate directions in the azimuth plane. Only three DC signals are required to control the seven PIN diodes attached along the spiral arm. The antenna has a 200-MHz-bandwidth around 3.3 GHz with stable maximum beam directions that are defined by setting of the switches. Considerations required in selecting switch positions when designing such antennas for other frequencies, are presented. The measured return loss, radiation pattern and gain, all have close correlation with the simulation results. A detailed comparison of our design with those already proposed in the literature is given.
