Patent ID: 11581649

Abstract:
Provided is an antenna for receiving radio waves including frequencies in the L6 band unique to QZSS to realize accurate positioning by QZSS. A substrate-type antenna 1 comprises an arcuate antenna element 20 including a long arcuate antenna element 22 and a short arcuate antenna element 24, each of which includes an integral antenna element compatible with three frequency bands and a single antenna element compatible with one frequency band and arranged with a space from the integral antenna element. Each of the integral antenna element and the single antenna element extends from an outer peripheral part of the arcuate antenna element toward an inner peripheral part thereof. The substrate-type antenna 1 further comprises a plurality of connection units 34 connected to the long arcuate antenna element 22 and the short arcuate antenna element 24, respectively, and a coupler 30 to which the plurality of connection units 34 is coupled.
