Abstract
A television antenna is constructed of a flat plate antenna comprising a plurality of concentric, rectangularly shaped loops formed of conductive material and disposed on a substrate. Each loop forms an antenna for signals in a predefined frequency band within the TV frequency spectrum. An additional loop is disposed within the plurality of concentric loops and is adapted for receiving signals in the FM frequency range. Each of the loops has four sides having an electrical length equivalent to one-quarter wavelength at a center frequency within a frequency band and each side of each antenna loop is connected to a side of another antenna loop and to one of a pair of antenna output terminals. The sides of each loop are formed by conductive strips deposited on a dielectric substrate which is particularly adapted for installation adjacent a dielectric roof panel or the like.
