摘要： A TV receiving antenna with broad band and capable of connecting with a coaxial cable comprising a sheet of electrically non-conductive synthetic plastic material; a pair of antenna elements of metallic foil in the shape of substantially a triangle or a combination of a triangle and a rectangle being superimposed on one side of said sheet, a pair of frequency compensating members of snake-shaped strip line of metallic foil connected to said antenna elements respectively being superimposed on the one side of said sheet; a pair of antenna elements of metallic foil in the shape of a trapezoid or a combination of a trapezoid and a rectangle being superimposed on the opposite side of said sheet; a pair of frequency compensating members of snake-shaped strip line of metallic foil connected to said antenna elements respectively being superimposed on the opposite side of said sheet; and impedance transformers of microstrip lines of metallic foil on each side of said sheet also superimposed for matching the antenna elements and the coaxial cable. Each antenna element can have a plurality of parallel slots for the selection of polarization. The antenna can receive TV signals both in UHF and in VHF bands and eliminate ghosts. It is suitable for mass production by etching the patterns on a laminated sheet for printed circuits.
