Wafer-scale coplanar waveguide slot-coupled Ka-band patch antenna for electronic scanning array of a future satellite communications system

This paper discussed about the successful simulated and measured data of the wafer-scale CPW slot-coupled K_a-band patch antenna presented above strongly advocate its candidacy for future integration with a MEMS-switched control board. Since it is a single-layer embodiment of the slot-coupling feed method, the total system weight is minimized and the complexity of the wafer-scale fabrication process is reduced. This, in turn, will yield a lightweight, cost-effective solution for a future microwave electronic scanning array for satellite communication.
