A monopole quasi Yagi antenna for the LTE APT 700 MHz band

In recent years the expansion of 4G technology has led to the appearance of the LTE APT 700 MHz band, which requires the development of antennas operating in this frequency band. This paper describes the design of a monopole quasi-Yagi antenna for this band. The active element has been designed as a T-shape monopole, allowing direct feeding, while the parasitic elements improve the directivity of the antenna. A prototype antenna was manufactured using FR4 substrate. The measured bandwidth of the antenna goes from 681.87 MHz up to 882.25 MHz and has a minimum gain of 2 dBi.
