Patent ID: 7183994

Claim:
A balanced compact antenna, comprising: first and second signal inputs; a first conductor line comprising a first portion extending from the first signal input in a first direction, a second portion extending from an end of the first portion a length L in a second direction, a third portion extending from an end of the second portion a length L 1 in a third direction, and a fourth portion extending from an end of the third portion a length L 2 in a fourth direction, the third direction being substantially parallel to the first direction, the second direction being substantially perpendicular to the first direction, and the fourth direction being substantially opposite to the second direction; a second conductor line comprising a fifth portion extending from the second signal input in a fifth direction, a sixth portion extending from an end of the fifth portion a length L in a sixth direction, a seventh portion extending from an end of the sixth portion a length L 1 in a seventh direction, and an eighth portion extending from an end of the seventh portion a length L 2 in a eighth direction, the fifth direction being substantially opposite to the first direction, the seventh direction being substantially parallel to the fifth direction, the sixth direction being substantially perpendicular to the fifth direction, and the eighth direction being substantially opposite to the sixth direction; and a third conductor line extending a length H from a center of the third conductor line toward both a first midpoint in the first conductor line and a second midpoint in the second conductor line, the third conductor line being separated from the first or second signal input by a distance d.
