Planar monopole antennas for digital TV, design, and measurement

Abstract

This article covers the design and evaluation of two wideband, low-cost elliptical planar monopole antennas designed for the Brazilian Digital TV System. The antennas had their performance evaluated in terms of their scattering parameters as well as in field measurements in a densely urbanized area, using a spectrum analyzer.

Broadband printed dipole antenna with integrated balun and tuning element for DTV application

“…The constructed antenna was tested, and its performance was The proposed antenna is compared with other DTV antennas reported in literature in Table 2. The antenna designs in references [6], [7], [23], [24], [26] and [27], in addition to covering the frequency band for digital TV receiver systems also cover frequency bands outside the specified Digital TV band (470-800 MHz) which can cause frequency interference from other transmitters that can degrade the quality of TV signal reception. The operating band of the dipole antenna in [25] falls short for DTV and it has a lower average gain than the proposed antenna.…”
