Patent ID: 7486241

Claim:
A card that interfaces an electronic device wherein the electronic device has a device height comprising: a card body having a width and opposing ends and a device end adapted to engage the electronic device across the width of the card body; a loop antenna mounted perpendicular on the end opposite the device end, wherein the width of the loop antenna is about the width of the card body and a height about one-half of its width less than the device height, wherein the loop antenna further comprises: a first portion having a first straight path segment followed by a meandering path segment followed by a second straight path segment, and two ends, the meandering path segment being about 50% of the length of the first portion, and second and third portions, each having a straight path and connected to respective ends of the first portion, wherein the antenna, is non-rotatable relative to the card, and has a generally rectangular shape with four sides, and the first, second and third portions are located along respective sides of the antenna, and the antenna has an antenna height that is less than the device height wherein said meandering path segment is split and a portion engages adjacent said card body and has a floating end and other end coupled to a current source or transceiver and operative as electrical delay lines and a full wavelength antenna.
