      This thesis presents the design of an ultra-wide band hybrid coupler, crossover and phase shifters for the design of four-input, four-output (4x4) stripline Butler matrix in order to feed an antenna array in 2-18 GHz ...
    • Dynamic Beamforming Without Phase Shifters 

      Ahmed, Taahir David (2017-04-20)
      Array beamforming is a widely-used technique for producing a flexible, retargetable, and tunable beam using fixed-position transmitting or receiving elements. It is well-understood, and widely used. Distributed and ...
    • Millimeter-Wave Concurrent Dual-Band Sige Bicmos Rfic Phased-Array Transmitter and Components 

      Bae, Juseok (2017-12-18)
      A concurrent dual-band phased-array transmitter (TX) and its constituent components are studied in this dissertation. The TX and components are designed for the unlicensed bands, 22–29 and 57–64 GHz, using a 0.18-μm BiCMOS ...
