This paper presents a horizontally polarized antenna with stacked-circular ring and stub for DTV reception. The operating frequency ranges from 470 MHz to 862 MHz at DTV frequency. The proposed antenna radiates horizontal polarization. The antenna structure is made from a thin brass sheet that consists of two circular rings. Each of circular ring consists of five dipole elements with each of circular ring on an air gap in the horizontal plane. The circular ring is fed by a 75 Ω coaxial transmission line. The simulated and measured results show that good impedance matching for |S11| is less than -10 dB, covering DTV frequency.
