摘要 |
FIELD: radio engineering; transceiving antennas for various radio systems, for instance, mobile objects. ^ SUBSTANCE: proposed hemispherical spiral antenna usually wound on surfaces of revolution incorporates provision for its matching with transmission line, uses combined power supply, and has dielectric hemisphere 1 attached to one side of metal screen 2 and wound with conductor 3 in the form of spiral; first high-frequency coaxial connector 4 secured on opposite side of metal screen whose central conductor is connected to one end of spiral; second high-frequency coaxial connector 5 secured in center of metal screen on side of first high-frequency coaxial connector 4; matching device 6 installed radially inside dielectric hemisphere 1 perpendicular to metal screen 2; central conductor of second high-frequency coaxial connector is connected to starting lead of central conductor 7 of matching device 6 and finishing lead of central conductor 8 of matching device 6 is connected to other end of spiral 3; it also has coaxial Tee whose output sides 10 and 11 are connected to inputs of first and second high-frequency coaxial connectors. ^ EFFECT: reduced axial dimensions and enlarged passband with respect to standing-wave ratio. ^ 1 cl, 2 dwg |
