Abstract :
The phaser is economical to fabricate and is geometrically well suited for use in phased array antennas. A 35-GHz model is described with exhibits a 2-GHz bandwidth. The model phase may be utilized either as a 360° latching device by using flux transfer switching, or can provide up to 800° of differential phase shift with holding current bias. The nominal insertion loss of the phaser is 2 dB with a VSWR <;1.3 across its bandwidth. The measured characteristics of the phaser show good agreement with computational values.
