HEARING AID BOWTIE ANTENNA OPTIMIZED FOR EAR TO EAR COMMUNICATIONS

摘要

A hearing aid is described which incorporates an antenna integrated into the housing that is configured to radiate with linear polarization such that the electric field is perpendicular to the head of a wearer. The described technique results in lower propagation losses from ear to ear and an improvement in ear-to-ear communications using a far-field link (e.g., in the 2.4 GHz band).

主权项

1. A hearing aid, comprising:
a housing; wherein the housing contains components that include a microphone for converting an audio input into an input signal, a digital processing circuitry for processing the input signal, an output state to produce an output signal in a manner that compensates for the patient's hearing deficit, and a wireless transceiver connected to the digital processing circuitry; an antenna having a feedpoint connected to the wireless transceiver; wherein the antenna is a bowtie-type antenna integrated with the housing and configured to radiate with polarization optimized for ear to ear communications.
