Abstract:
A planar inverted F antenna comprising:a non-rectangular radiating element comprising an internal side, an external side, and a peripheral edge; a dielectric carriage comprising a radiating side, a ground side, and at least one sidewall; the non-rectangular radiating element resides on the dielectric carriage such that the internal side of the radiating element resides closer to the radiating side of the dielectric carriage; a ground plane comprising a feed side and a carriage side; the dielectric carriage resides on the ground plane such that the carriage side of the ground plane resides closer to the ground side of the dielectric carriage; a slot; the slot resides in the internal side of the radiating element; a feed pin; the feed pin attached to the internal side of the radiating element; a dielectric carriage feed pin via hole; a ground plane feed pin via hole; the feed pin extends from the internal side of the radiating element through the dielectric carriage feed pin via hole and the ground plane feed pin via hole and is adapted to attach to a microstrip feed line; a conducting post; the conducting post attached to the internal side of the radiating element; a dielectric carriage conducting post via hole; the conducting post extends from the internal side of the radiating element to the carriage side of the ground plane through the dielectric carriage conducting post via hole and is attached to the dielectric side of the ground plane; a matching stub; the matching stub attached to the peripheral edge of the radiating element; and the matching stub has a downward extension from the peripheral edge of the radiating element and the matching stub not touching the ground plane; the matching stub is in flush with the sidewall of the dielectric carriage; and the matching stub has a downward extension from the peripheral edge of the radiating element, such that the matching stub resides off the ground plane and is flush with the sidewall of the dielectric carriage.
