Abstract:
1. A small device antenna system for a transceiver, comprising: an insulating layer having first and second opposing surfaces; a transmit loop element on the first surface, wherein the transmit loop element has a plurality of transmit loop segments disposed in a transmit zigzag configuration; and a receive loop element on the second surface, wherein the receive loop element has a plurality of receive loop segments disposed in a receive zigzag configuration, wherein each receive loop segment in the receive zigzag configuration is skew with respect to a closest transmit loop segment disposed in the transmit zigzag configuration, wherein the transmit loop segments in the transmit zigzag configuration extend away from a boundary of a central transmit loop area at a transmit segment angle less than or equal to ninety degrees from a first vector in a first direction, and wherein the receive loop segments in the receive zigzag configuration extend away from a boundary of a central receive loop area at a receive segment angle less than ninety degrees from a second vector in a second direction that is opposite the first direction.
