METAL WAVEGUIDE SLOT ARRAY FOR W-BAND MILLIMETER-WAVE SEEKER AND ANTENNA THEREFOR AND METHOD OF MANUFACTURING THE ARRAY

摘要

An antenna for a W-band millimeter wave seeker can remove the effects of adhesion residuals due to an existing dip brazing method since accurate metal adhesion is possible by using a diffusion adhesion method. Also, the antenna can be manufactured in an ultra-small size since an existing Ku-band monopulse type metal waveguide slot array antenna structure is used for a structure of an embodiment of the present invention. Such an antenna includes: a metal waveguide slot array for W-band millimeter-wave seeker which comprises a plurality of sub arrays; and a monopulse structure layer which receives each signal from the sub arrays and outputs a sum signal signal, an azimuth angle differential signal, and a vertical angle differential signal for the signals.
