Analysis and numerical simulation of a Ku-band analog reflection phase shifter based on radio-frequency microelectromechanical varactors

The topology of a Ku-band reflection phase shifter with microelectromechanical varactors as tunable elements is presented. The phase shifter dimensions are 4 × 4.85 mm. Its calculated operating frequency is 14 GHz, the 1-dB-loss bandwidth is 700 MHz, and the phase shift over the bandwidth is no less than 145 deg.
