A surface micromachined high gain dielectric lens antenna (DLA) for millimeter wave applications is designed, fabricated, and characterized. The designed DLA consists of a conductor-backed coplanar waveguide (CBCPW) fed coplanar patch antenna and a lens made of photopatternable epoxy, SU8, and supported by polydimethylsiloxane (PDMS). The antenna has a broad bandwidth of 6 % and a high gain of 7.54 dBi at 77 GHz.
