Title:
FEED APPARATUS, ANTENNA APPARATUS AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/131483
Kind Code:
A1
Abstract:
Provided in the present application are a feed apparatus, an antenna apparatus and a communication device. The feed apparatus is used for an antenna apparatus, wherein the antenna apparatus comprises a first radiation unit group and a second radiation unit group. The feed apparatus comprises a first cavity, a second cavity, a third cavity and signal lines. The signal lines comprise a first signal line, a second signal line and a third signal line, wherein the first signal line is used for connecting to the first radiation unit group of the antenna apparatus, and the second signal line is used for connecting to the second radiation unit group of the antenna apparatus. The first signal line is located in the first cavity, the second signal line is located in the second cavity, and the third signal line is located in the third cavity. The third signal line is used for electrically connecting to a radio frequency apparatus of a communication device, and the third signal line is electrically connected to the first signal line and the second signal line, respectively, such that the first signal line and the second signal line respectively feed the first radiation unit group and the second radiation unit group. Therefore, a reduction in the volume of a feed apparatus is facilitated, thereby improving the degree of integration and the degree of miniaturization of an antenna apparatus.
