Title:
MILLIMETER WAVE ANTENNA-IN-PACKAGE AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/164038
Kind Code:
A1
Abstract:
The present application provides a millimeter wave antenna-in-package and a terminal device. The millimeter wave antenna-in-package according to the present application comprises a substrate as well as a radiation structure and first antenna feeder that are provided inside the substrate; the first antenna feeder comprises an antenna matching branch, a feeder transmission band, and a first harmonic suppression unit; a first end of the antenna matching branch is connected to the radiation structure; the antenna matching branch extends from the first end in a first reference direction; the first harmonic suppression unit comprises a first transmission portion and a first bending portion; the first transmission portion extends in the first reference direction; a first end of the first bending portion is connected to a first end of the first transmission portion, and a second end of the first bending portion and a second end of the first transmission portion form a first opening; and a second end of the antenna matching branch is connected to the feeder transmission band by means of the first transmission portion, and the feeder transmission band extends in the first reference direction. The millimeter wave antenna-in-package according to the present application can achieve harmonic suppression at the antenna side, and at the same time, lowers precision requirements for the manufacturing process.
