The feed lines are impedance matched to the elliptical antenna elements by selecting a proper feedpoint inside the periphery of the elliptical antenna elements. Diodes connected between the feed lines and the ground plane rectify the microwave power, and microstrip filters (low pass) connected in series with the feed lines provide DC current to a microstrip bus. Low impedance matching strips are included between the elliptical elements and the rectifying and filtering elements.Field of SearchAircraft part of active antenna or vice versa | |
