A wireless data communication card configured in accordance with an example embodiment of the invention includes a low profile antenna arrangement that does not protrude from the housing of the computing device when the wireless data communication card is inserted into the housing. The low profile design is achieved without compromising the radio frequency ("RF") characteristics and performance of the wireless data communication card by tuning the antenna arrangement to account for conductive ground structure located within the housing of the computing device. In accordance with one practical embodiment of the invention, the wireless data communication card is compliant with IEEE Standard 802.11(b) and compliant with PCMCIA specifications.
