Abstract
An antenna (100) includes a rectangular dielectric substrate (102); and a U-shaped conductive strip attached to a first surface of the substrate, the U-shaped conductive strip having two side members (202, 203), each about one-eighth a predetermined wavelength in length, and an end member (204) forming a substantially rectangular slot (206) extending parallel to the long edges of the substrate, the slot closed at a first end (212) by the end member, and open at a second end (208). The antenna further includes a microstrip feed line (104) attached to a second surface of the substrate opposite and parallel to the first surface for coupling an RF signal between the antenna and an RF device (502), the microstrip feed line extending across and perpendicular to the slot proximate the second end of the slot, and further extending across a portion of the two side members; and a ground point (210) electrically coupled to a first one of the two side members of the U-shaped conductive strip and positioned proximate the second end of the slot.
