Abstract
The article discusses ways to increase the operating frequency band of a symmetrical broadband vibrator in printed version for a phased array antenna. The equivalent circuit of such an emitter is described. Various designs of an emitter made on a Rogers RT5880 dielectric substrate with a thickness of t = 1.5 mm and εr = 2.2 and the results of electromagnetic modeling are considered. A wide working band is achieved due to the introduction of a dual-circuit system and a modified geometry of the vibrator arms. Topologies, as well as matching and directivity characteristics of three types of antennas are given. The developed antenna is intended for use in broadband systems both as a separate independent antenna and as a radiator for digital phased antenna arrays. The CST Microwave studio environment was used to simulate the emitter.
