ABSTRACT:
A patch antenna for operation within a high temperature environment. The patent antenna typically includes an antenna radiating element, a housing and a microwave transmission medium, such as a high temperature microwave cable. The antenna radiating element typically comprises a metallization (or solid metal) element in contact with a dielectric element. The antenna radiating element can include a dielectric window comprising a flame spray coating or a solid dielectric material placed in front of the radiating element. The antenna element is typically inserted into a housing that mechanically captures the antenna and provides a ground plane for the antenna. Orifices or passages can be added to the housing to improve high temperature performance and may direct cooling air for cooling the antenna. The high temperature microwave cable is typically inserted into the housing and attached to the antenna radiator to support the communication of electromagnetic signals between the radiator element and a receiver or transmitter device.
