1. An antenna structure for a portable radio transceiver device, comprising:
an inverted F section having a feed point, an inductive feed shunt coupled between the feed point and a ground, and a meander portion having a distal end opposite the feed point; a monopole section having a first end and a terminal end, the first end coupled to the distal end of the inverted F section; a helical section coupled to the terminal end of the monopole section; and wherein the monopole section comprises a first monopole element and a second monopole element coupled in series, the first monopole element coupled to the distal end of the inverted F section, the second monopole element coupled to the helical section, the first and second monopole elements having different orientations, the first monopole element is a substantially U-shaped element having a planar configuration oriented in a plane that is orthogonal to a plane of orientation of the meander portion of the inverted F section, wherein the meander portion is disposed on a circuit board, and the first monopole element is disposed on a carrier element separate from the circuit board, and wherein the first monopole section is coupled to the distal end of the meander portion via a spring contact. |
