Claim:
1. A method for wireless communication with a hearing aid, comprising: providing a hearing aid with a parallel-loop antenna including an antenna conductor having loop portions and connecting portions each connecting between the loop portions, the loop portions each having a loop plane, the connecting portions each having a connecting plane approximately perpendicular to each of the loop planes; providing the hearing aid with a communication circuit configured to perform the wireless communication using the antenna; providing a feed-line including two branches each including an antenna pad for making connection to the antenna, a circuit pad for making a connection to the communication circuit, and a feed-line conductor coupled between the antenna pad and the circuit pad and having a plane; and reducing capacitance resulting from crossover of conductors and reducing electrical imbalance associated with the feed-line, by connecting the antenna to the communication circuit with major portions of the planes of the feed-line conductors each approximately perpendicular to each of the loop planes of the antenna conductor and approximately perpendicular to each of the connecting planes of the antenna conductor and with the major portions of the planes of the feed-line conductors centered at a space between connection points between the antenna and the feed-line conductors.
