1. A hearing assistance device, comprising:
- a housing;
a power source;
a radio circuit within the housing and electrically connected to the power source;
a flex circuit antenna having an aperture, wherein the radio circuit is at least substantially within the aperture, wherein the antenna has two substantially parallel loops conforming to an inner portion of an outer perimeter of the housing to an extent approximately extending to an inner wall of the housing, each of the two substantially parallel loops proximal to opposite wall portions of the housing; and
a transmission line to electrically connect the antenna to the radio circuit,wherein the housing has a long axis, and the flex circuit antenna forms a loop in a plane substantially perpendicular to the long axis of the housing and the aperture has an axis substantially parallel to the long axis, andwherein the flex circuit antenna includes a first portion, a second portion and a third portion, the first and second portions form a first aperture, the first and third portions form a second aperture.
