Abstract

This paper presents a micromachined patch antenna array with an integrated 2x2 Butler matrix (BM) beamformer. It
was designed at 63 GHz and simulated using CST Microwave
Studio 3D simulator. The BM is made using a low loss air filled rectangular coaxial line. The structure is constructed by bonding five layers of gold coated photoresist SU-8, each 200 microns thick. The experimental result shows a good matching achieved with return loss of -13 dB and inter-port isolation of about -22 dB at 63 GHz.
