Abstract:
An antenna feed system for directing antenna signals to and from receiver and transmission circuitry, said system comprising:a conductive structure;an antenna element positioned adjacent to the conductive structure so as to define a notch therebetween;a first antenna feed connected to the antenna element at a first feed point location so as to be impedance matched to the antenna element at a first bandwidth said first feed extending across the notch and being coupled to the conductive structure; anda second antenna feed connected to the antenna element at a second feed point location so as to be impedance matched to the antenna element at a second bandwidth, said second feed extending across the notch and being coupled to the conductive structure, wherein the first bandwidth has a different frequency than the second bandwidth, said first and second feeds being impedance matched to the antenna element to be at the first and second bandwidths.
