Abstract
A reduced profile panel antenna is disclosed. A panel antenna configured according to an embodiment includes two opposing antenna arms disposed over a ground plane. The antenna arms include one or more corrugated or folded sections to increase the electrical path of the antenna arms within fixed physical dimensions (e.g., length and width) of the panel antenna. The panel antenna also includes passive filters to provide current loop paths of varying lengths for selected frequency ranges. Longer loop paths are employed for signals at lower frequencies (i.e., longer wavelengths) and shorter loop paths are employed for signals at higher frequencies (i.e., shorter wavelengths). The panel antenna further includes a ferrite plane disposed between the ground plane and the antenna arms to suppress radio frequency (RF) signal reflections and allow for a reduced antenna profile or thickness.
