Abstract
A broadband patch antenna including a planar metallic patch sheet that is provided with right-angled edges and is disposed at a predetermined first height above and parallel to the planar base area of an electrically conducting reflector, and a device for feeding an RF signal into the metallic patch sheet. The feeding device encompasses a conductor which is guided in a vertical direction and is insulated through the base area of the reflector and terminates at a feeding point on the metallic patch sheet. To significantly improve the broadband range while keeping the structure of the antenna simple, the metallic patch sheet has the shape of a cross and the conductor of the feeding device is an inner conductor of a coaxial conductor that is positioned between the base area of the reflector and the metallic patch sheet.
