UHF ERES Antenna for UHF RFID Applications
2020 23rd International Microwave and Radar Conference (MIKON), 2020This paper presents Electronically Reconfigurable Superstrate (ERES) antenna capable of modifying the shape of the radiation pattern in an uncomplicated way. The approach adopted in this concept is based on switching the state of passive patch elements placed on an additional layer located above a simple microstrip patch antenna. In order to change the

The implementation of DTV is forcing every television broadcaster to purchase a new antenna. Choosing the best antenna to meet all of the station's needs is not a simple task. With tower space at a premium, tower leasing rates soaring, and FCC deadlines approaching quickly, the broadcaster faces new and non-traditional issues-for example: Do I co ...

The use of fractal antenna techniques to reduce the size of a UHF linear dipole is investigated and discussed. Fractal designs are derived using an empirical method and a genetic algorithm based method. While both achieve size reduction, the latter design shows the most promise from a size reduction and design methodology standpoint, since simulation ...

Broadband UHF flexible vivaldi antenna
2013 Loughborough Antennas & Propagation Conference (LAPC), 2013A novel Vivaldi flexible antenna with a -6 dB bandwidth from 150 MHz up to 900 MHz is presented. The whole antenna is realized on a 600 × 600 mm2 silicone foam substrate. In this paper we describe the design, the realization and the performances of this high gain and directive antenna.

Theoretical and experimental results have shown that a satellite repeater can be used to measure accurately transmit and receive gains of ground-communications antennas. The satellite provides a uniform phase front and, for any appreciable elevation angle, meets the height requirement as a boresight source for large-aperture antennas.
