PROJECT TITLE :

Beam Switching Conformal Antenna Array for mm-Wave Communications

ABSTRACT:

During this letter, the planning and measurement results of a millimeter-wave beam switching antenna are presented. Many antenna prototypes have been fabricated and measured in planar and conformal installations. The developed prototype consists of three antenna arrays of 16 patch elements in every array and it's operating at sixty one GHz with linear polarization. One-pole three-throw semiconductor switch is hooked up to the manufactured prototype using copper pillar attachment. The main beam direction of the convex antenna can be modified by switching between the antenna arrays within the prototype. [*fr1] sphere three-D radiation pattern measurements are performed. For the convex prototype, bent on the cylinder with radius twenty five mm, beam switching with -thirty two° / + thirty four° degrees is achieved.
