Document Type and Number:
Japanese Patent JP6967410
Kind Code:
B2
Abstract:
A high gain of an antenna is achieved while suppressing interference of a radio wave from an RFIC. A plurality of serial-type radiation element rows 41 are arranged in parallel. A parallel feed line 45 branches from a feed terminal of an electronic component 11, and connects radiation elements 42, at ends of the serial-type radiation element row 41 farthest from the electronic component 11, to the feed terminal of the electronic component 11. All of the serial-type radiation element rows have an identical path length, along the parallel feed line 45, from each of the radiation elements 42 at the ends farthest from the electronic component 11 to the feed terminal of the electronic component 11. An amplifier 61 is connected to the parallel feed line on a halfway portion of the parallel feed line 45. The amplifier 61 amplifies a signal passing through the parallel feed line 45.
