UHF TV Band Transparent Antenna for Indoor Television Reception

Article Preview

Abstract:

The characteristics of transparent antenna for indoor television reception are investigated. It operates at Ultra High Frequency (UHF) band. The proposed antenna was made from silver coated polyester film (AgHT-4), the transparent conductive material and it is attached on a layer of glass substrate at both sides. The overall antenna length and width is at 150 mm x 50 mm. It has not fully ground plane and fed by a 50 Ω feedline. The meander line is designed at the feedline to broader the bandwidth. The simulated bandwidth obtained is 505.37 MHz to 802.45 MHz at level -6 dB. The rough impedance bandwidth is 297.08 MHz or 45.43 %. All the radiation patterns over the UHF band show bi-directional for E-plane and omni-directional at H-plane. The maximum gain obtained is 1.88 dBi.
