Abstract
An antenna apparatus can include a transmission medium that is positioned within layers of an antenna apparatus that are positioned adjacent to a first upper layer that is configured to include a signal receiving and transmission element (e.g. an antenna, patch antenna, etc.). The transmission medium can include or otherwise be connected to one or more resonators so that only a signal within a pre-selected band is passable through the transmission band. Any signal in a band outside of the pre-selected band may not be passable through the transmission medium due at least in part to the resonators. In some embodiments, the transmission medium may be part of a stripline or a microstrip. Embodiments of the apparatus may also be configured to block backward radiation emittable from the antenna to help prevent a body of a person near that device from absorbing such radiation.
