Title: Antenna module for portable computer

Abstract: An antenna module 30 of the present invention comprises a wire first dipoleantenna arm 32 oriented in a first direction and a wire second dipoleantenna arm 34 oriented in a second direction that is perpendicular to thefirst direction, said two arms being respectively electrically connectedto a printed circuit board 36 at two points, and a gap G being formedbetween the two points. Said two antenna arms are interfaced to theassociated transmitting/receiving circuitry by a coaxial cable 38. Valuesof the length of the two arms, the length of the gap, the diameter of eacharm, an impedance of the coaxial cable, and an operating frequency rangeare chosen to obviate the need for matching circuitry to perform thefunctions of transfer, balancing and matching between the first and seconddipole antenna arms. Therefore, the antenna module is simplified and canbe placed compactly at a corner of the portable computer to provideimproved performance.
