1. A hearing aid configured for performing wireless communication with another device, the hearing aid comprising:
- a case;
a hearing aid circuit housed in the case, the hearing aid circuit configured to perform the wireless communication; and
an antenna including a primary element and one or more secondary elements, the primary antenna element wired to the hearing aid circuit and configured to receive a signal from the hearing aid circuit and transmit the signal to the one or more secondary elements, the one or more secondary antenna elements wirelessly coupled to the primary antenna element and including one or more conductive loops configured to receive the signal from the primary antenna element and transmit the signal to the other device.

Abstract
A hearing aid includes an antenna for wireless communication with another device. The antenna includes a primary element connected to the circuit of the hearing aid and one or more secondary elements parasitically coupled to the primary element. This antenna configuration substantially increases radiation efficiency when compared to an antenna with the primary element alone, without substantially increasing the size, power consumption, and complexity of the hearing aid.
