A Wide Scanning Ka Band Phased Array Antenna

Abstract

The sixteen-element phased array antenna has been demonstrated at 35GHz. An array element pattern suitable for a wide-scanning phased array antenna can be formed the printed dipole antenna with a parasitic element.In this paper, it verifies the characteristic of beam width, antenna gain and ripple of an active element pattern at the change of the length and the distance of parasitic element. The beam scanning characteristic of 114 degrees in E-plane has been obtained at phased array antenna used this antenna with parasitic element which optimum for wide scanning.
