摘要：A miniature phased array antenna system is described which employs a
substrate having a high dielectric constant. A plurality of antenna elements is located ona surface of the substrate, and a superstrate having a high dielectric constant covers theantenna elements. The dielectric constant, thickness, and shape of the superstrateenable it to act as a dielectric lens for controlling the phase relationship of a signalreceived by the antenna elements. The design of the superstrate dielectric lens permits areduction in the physical spacing between the antenna elements while maintaining spatialdiversity in phase between signals arriving from different directions. Thus, the antennaarray may be significantly smaller than previously proposed phased array antennas whilemaintaining a similar phase relationship to that achieved using previously proposedphased array antennas. Electronic circuitry coupled to each of the plurality of antennaelements applies complex weights to received signals prior to a summation thereof inorder to reconstruct a desired signal and to deconstruct an undesired signal. SAW filtersemployed in the electronic circuitry are temperature controlled to maintain group-delayand phase-offset stability.
