Characterization of All-Metal Multi-Feed Antenna for High Power Applications
conference paper
An all-metal antenna with multiple feeding points for high power applications is presented in this paper. The radiating element is a stacked patch fed by coupled slots, and it is composed only by stacked metal layers realized by milling machining, ensuring a reliable thermal behaviour of the antenna for high input power level applications. The multi-feed strategy of the antenna is realized on a multi-layer substrate, enclosed in a metal cavity within the antenna structure, supporting four striplines feeding the slots. such transmission lines are meant to be connected to four HPAs. The demonstrator is a stand-alone radiating element, which has been retuned from the radiating element designed in array environment in order to support an EIRP of 30dBW over a wide scanning range, _max s = 50_ for all '-planes, over 15% bandwidth.
