Double-Dielectric Microstrip Ultrahigh-Frequency Antenna For Digital Terrestrial Television

Featured ApplicationAlthough Yagi-Uda antenna is more than 80 years old and is still globally the most used antenna for TV reception, we believe that there is still room for improvement. This article discusses a new antenna design for application in terrestrial TV broadcasting. With regard to the antenna's performance, our results are not limited to simulations. We present a prototype of a practical antenna supported by measurement results. This paper contributes to motivating and increasing research in the domain of antennas for digital terrestrial TV bands.In many countries, terrestrial broadcasting is the main delivery medium for television. In this paper, we propose a small-volume practical receiving antenna. Our design consists of a linear array of three vertically placed patch antennas which increase antenna gain. The antenna has a double-dielectric substrate (FR4 + air) in order to increase efficiency and bandwidth. In this paper, we also discuss simulations and practical results, and demonstrate that the proposed double-dielectric microstrip antenna is a viable design choice for digital terrestrial TV (DTT) reception. The designed antenna reached a gain of 10.5 dBi at the desired central frequency of 754 MHz.
