Title:
LOW-BAND RADIATOR AND MULTI-BROADBAND ANTENNA COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/225245
Kind Code:
A1
Abstract:
A low-band radiator of the present invention comprises: a radiation substrate; a first dipole radiation portion formed from a conductor line on one surface of the radiation substrate and comprising two first loop arms each having the length extending in a predetermined first direction and formed in a loop shape having one end open; a second dipole radiation portion formed from a conductor line on one surface of the radiation surface, comprising two second loop arms each having the length extending in a predetermined second direction and formed in a loop shape having one end open, and disposed so as to intersect the first dipole radiation portion; and a balun portion coupled to the other surface of the radiation substrate and applying power feeding signals, respectively corresponding to the first and second loop arms, to two open ends of the loops. Therefore, the present invention may provide: the low-band radiator having improved isolation between the low-band radiator and a high-band radiator, having a minimized effect on the radiation pattern of the high-band radiator, and capable of being manufactured in a small size; and the multi-broadband antenna comprising same.
