Abstract
A PCMCIA antenna for wireless communications is provided which provides the performance of a 1/2 wave antenna used for wireless communication, both transmission and receiving, on PCMCIA and other platforms for wireless data communications. The antenna comprises a housing which is adapted to be secured and supported by the host device and comprises a housing including housing members which are ultrasonically welded together. A flexible circuit board is provided in the housing which serves as the lower radiating element. A coaxial cable extends into the housing and has its braid soldered to the lower radiating element so that the same serves as a counterpoise for the antenna. The center wire of the coaxial cable is connected by a flexible trace to a flexible printed circuit board which is encased in an insulated sheath which forms the upper radiating element. The upper radiating element is pivotally secured to the housing so that the upper radiating element may be moved to a stowed position wherein it is parallel to the longitudinal axis of the housing, where it may be pivotally moved upwardly with respect to the housing to a 90 degree angle with respect to the housing.
