The design, fabrication and testing of a conformal K-band circular array is presented. The array consists of sixteen linearly tapered slot antennas (LTSA). It is fed by a 1:16 microstrip line power splitter via electromagnetic coupling. The array has an omni-directional pattern in the azimuth plane. In the elevation plane the beam is displaced above the horizon. In mobile communications and intelligent vehicle highway systems (IVHS) there is a need for low cost conformal antennas. These antennas must also have a toroidal shaped radiation pattern in order to receive signals from all directions. One configuration that can meet these requirements is a circular array of LTSAs. This paper presents the demonstration and fabrication at K-Band of such an array. The LTSA array was fabricated on the top surface of a thin dielectric substrate. The feed network consisting of a sixteen way microstrip power splitter was fabricated on the opposite side of the substrate and electromagnetically coupled to the array. During testing, a metal ground plate was placed below the array to simulate the top surface of a vehicle.
