Abstract
The ferroelectric lens is a new type of phased array antenna. It uniquely incorporates bulk phase shifting using bulk ferroelectric ceramics to reduce the cost of the phased array. This paper presents the latest X band (8-12 GHz) results with improved ferroelectrics; the loss due to these ferroelectrics is less than 2 dB for obtaining 360° differential phase shift at 10 GHz. The antenna pattern of an interferometer built with ferroelectrics and demonstrating electronic scanning at 10 GHz is presented. A brief review of the ferroelectric lens concept is also included.
