Abstract :
A phased array antenna with electronic beam scanning capabilities was designed based on the integration of the multilayer ferroelectric phase shifter and the coplanar waveguide continuous transverse stub technology. A new biasing approach for the multi-dielectric layer phase shifter is proposed and simulation results demonstrated its effectiveness in biasing the tunable ferroelectric layer. A three element phased array was designed at 10 GHz and the obtained simulation results of the integrated phase shifter and CTS designs demonstrated nearly 31deg of beam scanning in conjunction with good impedance match. Efforts to develop designs that increase the beam steering capabilities are underway. Experimental verification of these simulation results for both the phase shifters and the integrated phase shifter/CTS phased array antenna design are currently being pursued
