Thin Ceramic Ferroelectric Phase Shifter for Steerable Microstrip Patch Antenna Array

The possibility of having an electronically steerable antenna system is of significant current importance for many communication technologies. Applications such as airport traffic control, satellite tracking for mobile communication system, and radar systems emphasize the importance of electronically steerable antennas. A novel design using ferroelectric material which dramatically reduces the size and the cost of the phase shifter used to achieve an electronically steerable antenna system is presented in this paper. A total beam scan of 36° is obtained for a two element microstrip antenna system while the side lobe level is kept below 10 dB, and the reflection coefficient at resonance frequency is maintained below 20 dB.
