Abstract
A method (1400) and an RF circuit (100, 400, 700, 1000, 1100, 1200, 1300) for a wireless communication device that mitigates near field radiation generated by the wireless communication device. At least one counterpoise (104, 404, 1304) can be configured to resonate at or near at least one operating frequency of an antenna (102) of the wireless communication device. The antenna can be a component of the RF circuit. The counterpoise can be electromagnetically coupled to the antenna to mitigate near field radiation of the antenna at the at least one operating frequency of the antenna in order to comply with an applicable hearing aid compatibility (HAC) specification.
