Abstract:
An antenna responsive to a plurality of frequency bands, comprising:a radiating element geometrically configured to be responsive to said plurality of frequency bands; a ground plane element positioned away from said radiating element to thereby define a space between said ground plane element and said radiating element; an antenna-feed connected to said radiating element; a device-feed for connection to a radio device; a transmission line connected between said antenna-feed and said device-feed; a plurality of transmission line stubs associated with said transmission line; at least one frequency responsive high impedance circuit responsive to at least one frequency within said plurality of frequency bands; and at least one transmission line stub connected to said transmission line by way of said at least one frequency responsive high impedance circuit such that said radiating element is matched to said radio feed within each of said plurality of frequency bands, as said at least one frequency responsive high impedance circuit operates to dynamically reconfigured said transmission line in accordance with a frequency band currently traversing said transmission line.
