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.

AbstractThe paper describes the design and development of a low profile wide scanned conformal active 1 × 32 phased array antenna for Ku-band SATCOM applications. The realized antenna is diagonally polarized and covers full transmit frequency band (i.e. 13.75–14.5 GHz) of Ku band SATCOM. All the developed sub-systems of the antenna, i.e. conformal radiating array, conformal transmit module, manifold network, and beam steering unit are described. The VSWR of the antenna is better than 1.65 over the complete transmit frequency band. The antenna has the beam steering capability of ±60° in the array plane. Designed antenna is best suited for airborne applications, where antenna profile contributes considerable aero drag and RCS to the host platform.
