Abstract
An integral diversity antenna especially suited for use in a laptop computer device without the need for changing or otherwise altering such devices pre-established form factor. Two separately located printed circuit board antenna structures are orthogonally mounted in an associated counterpoise. One such antenna structure is vertically polarized and the other horizontally polarized. In this manner, both spatial and polarization diversity is achieved. The counterpoise serves the additional purpose of affecting both RFI and EMI shielding of the laptop computer's LCD display and driven circuitry.
