This paper presents the design, fabrication and " on wafer " characterization of membrane-supported Yagi-Uda CPW fed antenna structures. The antennas were designed for the 60 GHz and 77 GHz frequency operating ranges. The 60 GHz antennas were fabricated on a semi-insulating GaAs membrane using GaAs micromachining. The 77 GHz a ntennas were manufactured on(More)
This paper investigates a series of membrane supported millimeter wave transmission lines up to 110 GHz. The structures were fabricated using high resistivity silicon micromachining (wet etching). Three approaches, based on full-wave electromagnetic simulations, analytic closed form equations and equivalent circuit were used in the investigation process.(More)
This paper describes the design, manufacturing and experiments of a lumped element band pass filter in a new topology. The design starts from a second order capacitive coupled resonator topology. An additional series inductor is inserted in the filter classical topology, for shifting two transmission zeros on the real frequency axes in the filter's band(More)
