Millimeter wave conformal slot antenna
View Patent ↗The system and method for a conformal millimeter wave (mmW) cavity backed slot antenna with near positive gain and hemispherical gain coverage. The antenna has a microstrip launch and feed and a surface mount connector. The mmW antenna may have a stripline launch or waveguide launch instead of a microstrip launch. In some cases, the microwave electronics can be mounted on the launch substrate instead of a connector.
