A hearing instrument comprises a wireless communication unit interconnected with an antenna for emission and reception of an electromagnetic field having an RF wavelength, a speaker interconnected with the wireless communication unit and being configured to provide an output audio signal. A battery is configured to supply power to the hearing instrument and a filter circuit interconnects the battery and a power management circuit of the hearing instrument. The antenna extends from a feed and at least a part of the antenna being is arranged adjacent the battery. A distance between the at least part of the antenna and the battery is below 1/40 of the wavelength. The filter circuit is configured to de-couple the battery and the power management circuit at frequencies above 3 MHz and configured to connect the battery to the power management circuit at frequencies below 300 kHz.

Examples of a patch antenna are described herein. Some examples of the patch antenna include a parallelepipedal antenna holder. In some examples, a first excitation surface is situated on a first side of the antenna holder, where a second side opposite the first side is situated on a metal plane. A grounding surface is situated on a third side between the first side and the second side. An excitation radiator feed is situated to provide electromagnetic coupling between the excitation radiator feed and the first excitation surface.
