摘要：The invention provides an efficient, broadband, antenna system for RFcommunications. The benefits of the invention include: a single integrated system fortotal band coverage; high system efficiency across the operating band; multipleinstantaneous transmit and receive signal capability; and simple mechanical assemblies.The invention includes various configurations of multiple transceivers connected to a setof RF filters and associated impedance matching networks which are used to excite aplurality of trapped antenna elements. The new antenna system, offers control over theantenna's directivity and the antenna's driving point impedance by using sub-bandsystems as defined by a series of RF filters and traps which divide the physical antennaelements into various radiating lengths. Continuous coverage over the entire frequencyband of interest is achieved by using different physical antenna elements for adjacentsub-bands. The utilization of sub-bands reduces the impedance matching networkrequirements and helps to more efficiently radiate energy over the entire frequencyband of interest. The resultant higher antenna system efficiencies allow for moderateand feasible performance specifications for transmitters, receivers, and matching networkcomponents.
