WIRELESS MODULE
Document Type and Number:
WIPO Patent Application WO/2019/058636
Kind Code:
A1
Abstract:
The present invention achieves a high gain for an antenna while limiting radio wave interference caused by RFIC. In the present invention, a plurality of serial radiation element rows 41 are aligned in parallel, and a parallel power feeding line 45 branches from a power feeding terminal of an electronic component 11 and connects the power feeding terminal of the electronic component 11 with radiation elements 42 at the end furthest away from the electronic component 11 among the serial radiation element rows 41, and the path lengths from the furthest radiation elements 42 to the power feeding terminal of the electronic component 11 along the parallel power feeding line 45 are equal for any of the serial radiation element rows. An amplifier 61 is connected to the parallel power feeding line in the middle of the parallel power feeding line 45 and the amplifier 61 amplifies signals passing through the parallel power feeding line 45.
