The multilayer compound bases on Liquid Crystal Polymer (LCP) and common RF substrates. The integration of the RF components as well as thermal and mechanical aspects are addressed. A complete 4x4 Ka-Band array providing polarization multiplex is demonstrated. Far-field measurements of the antenna elements are discussed.en0149-645x2009809812IEEEActive antennasHybrid integrated circuitsMultiplexingPolarizationIngenieurwissenschaftenConference Paper10.1109/MWSYM.2009.5165820Conference Paper
