Abstract :
A Micro-Electro-Mechanical System (MEMS) based Q band Substrate Integrated Waveguide (SIW) multi-beam antenna was designed, fabricated and measured. Fed by a 4×4 SIW Butler matrix, the prototype antenna can generate 4 beams simultaneously with respect to its 4 ports. The radiators of the proposed antenna are SIW transverse slots. At 45GHz, the measured 4 beam angles with respect to normal direction are -15°, -40°, 15° and 40°.
