Abstract
A high gain antenna for direction finding in the Ka-band. The antenna consists of a lens antenna fed by two micro strip patch antennas. The printed patch antennas are fed by a 180 degree hybrid coupler having four ports, with two ports connected to the feeds of the patch antennas and the other two ports connected to the receiver/exciter. The hybrid sums the signals from the patches and subtracts the signals from the patches to form sum and difference channels. By comparing the sum and difference channels, a user can determine whether the signal entered through the main beam. For example, if the sum signal is greater than the difference signal, the signal is in the main beam. If not, the signal came from another angle.
