Title:
ANTENNA UNIT, FILTERING ANTENNA, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/040764
Kind Code:
A1
Abstract:
Provided in the present application are an antenna unit, a filtering antenna, and a terminal device. The antenna unit comprises: a first dielectric substrate, a second dielectric substrate, a third dielectric substrate, a radiation structure and at least one transmission unit. The transmission unit comprises a first feed structure, a second feed structure and a filtering structure; the second dielectric substrate is arranged between the first dielectric substrate and the third dielectric substrate; the radiation structure is arranged on the side of the first dielectric substrate away from the second dielectric substrate; the second feed structure is arranged on the second dielectric substrate; the filtering structure is arranged on the third dielectric substrate; the first feed structure is connected to the second feed structure and the filtering structure; the first feed structure is used for transmitting an electromagnetic wave signal; the second feed structure is used for coupled feeding to the radiation structure; the filtering structure is used for filtering. The design of combination of an antenna and a filter reduces the device size and achieves low cost, high stability and good filtering characteristics.
