COMPACT TWO-MODE INTEGRATED SET OF ANTENNAS FOR GROUND CELLULAR AND SATELLITE TELECOMMUNICATIONS

摘要

FIELD: antennas for communications within any desired frequency band. ^ SUBSTANCE: proposed integrated set of antennas has cellular communications antenna and satellite communications antenna. Preferable design alternate of antenna for satellite communications is quadrifilar spiral antenna and for cellular communications is coaxial-screen dipole antenna. Spike of coaxial-screen dipole antenna is positioned along axis in center of quadrifilar spiral antenna. Such positioning enables operation in satellite communications frequency band and in cellular communications frequency band with negligible electromagnetic coupling. Radiophones equipped with such antenna sets can function with ground cellular or satellite communication system. ^ EFFECT: enlarged functional capabilities. ^ 8 cl, 3 dwg
