Abstract
An active antenna for UHF/VHF signal receiving is described, the active antenna being capable of configuration in one of a plurality of possible modes. The active antenna includes an antenna element configured for multiple resonances in the UHF/VHF bands, and capable of generating multiple radiation modes as well as active impedance matching using a microprocessor and multi-port switch having variable or multiple selectable modes. The active antenna may include a second antenna element arranged in a right-angle orientation with respect to the first antenna element. The first antenna element, second antenna element, or a combination may be selected for receiving signals in at a desired frequency. A three-dimensional antenna assembly is also described. Each of the examples illustrate an active beam steering antenna capable of UHF/VHF signal receiving.
