Abstract
An antenna comprising an antenna element and a counterpoise. The antenna element is positioned to minimize capacitive coupling between the antenna element and the counterpoise. In one embodiment no portion of the antenna element overlaps the counterpoise decreasing the distributed capacitance between the antenna element and the counterpoise and increasing the effective bandwidth of the antenna. The antenna element can be configured to couple with substantially all of the counterpoise to radiate at a resonant frequency.
Claims23
An antenna comprising:
- an antenna element;
- and
- a counterpoise positioned such that no portion of the counterpoise overlaps with the antenna element but close enough to the antenna element to cause the counterpoise to act as a parasitic element of the antenna element.
An antenna comprising:
- an antenna element;
- and
- a counterpoise positioned such that no portion of the counterpoise overlaps with the antenna element but close enough to the antenna element to cause the antenna element and counterpoise to operate in a single collective mode.
An antenna comprising:
- an antenna element;
- and
- a counterpoise positioned such that at least a portion of the antenna element does not overlap with the counterpoise and the antenna element couples with substantially all of the counterpoise.
