Wireless data communication card with compact antenna

An antenna arrangement for a wireless data communication card configured for coupling and use with a physically separate and distinct computing device having a computing device housing, said antenna arrangement comprising:

• a radio frequency (“RF”) ground structure for establishing RF ground coupling to conductive structure of the computing device;
• a first antenna element having a first input section and a first radiating section coupled to said first input section, said first radiating section being oriented in a first direction;
• and
• a second antenna element having a second input section and a second radiating section coupled to said second input section, said second radiating section being oriented in a second direction opposing said first direction;
• wherein
• said first input section and said second input section are separate and distinct elements;
• and
• said first antenna element and said second antenna element are tuned in accordance with said conductive structure of the computing device.

A computing device system comprising:

• a computing device comprising:
• a computing device housing;
• a card slot formed in said computing device housing;
• conductive structure contained in said computing device housing;
• a wireless data communication card configured for engagement with said card slot of said computing device, said wireless data communication card being physically separate and distinct from said computing device, and said wireless data communication card comprising:
• a conductive outer housing that provides a radio frequency (“RF”) ground structure, said conductive outer housing establishing RF ground coupling to said conductive structure of said computing device;
• an RF communication module located within said conductive outer housing of said wireless data communication card;
• an antenna arrangement coupled to said RF communication module and located external to said conductive outer housing of said wireless data communication card, said antenna arrangement being tuned to account for said conductive structure of said computing device, and said antenna arrangement having a low profile such that said antenna arrangement is enclosed within said housing of said computing device when said wireless data communication card is engaged in said card slot, said antenna arrangement and comprising:
• a first antenna element having a first input section protruding from said conductive outer housing, and a first radiating section, coupled to said first input section, oriented along said antenna end in a first direction;
• and
• a second antenna element having a second input section protruding from said conductive outer housing, and a second radiating section, coupled to said second input section, oriented along said antenna end in a second direction, wherein said first input section and said second input section are separate and distinct elements.
