Title:
FEED DEVICE, DUAL-FREQUENCY MICROWAVE ANTENNA AND DUAL-FREQUENCY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/019264
Kind Code:
A1
Abstract:
The present application provides a feed device, a dual-frequency microwave antenna, and a dual-frequency antenna device. The feed device comprises a low-frequency feed and a high-frequency feed, the high-frequency feed is embedded in the low-frequency feed, and the low-frequency feed comprises a plurality of low-frequency array elements arranged in an array, and the high-frequency feed comprises a plurality of high-frequency array elements arranged in an array; at least one high-frequency array element is embedded inside one low-frequency array element, and the low-frequency array element has a common waveguide wall with each of the high-frequency array elements embedded inside the low-frequency array element, such that the high-frequency feed is effectively integrated with the low-frequency feed, having a compact structure, and enabling the high-frequency feed and the low-frequency feed to have good equalization; furthermore, beam scanning of the antennas in a high-frequency band can be realized by switching the plurality of high-frequency array elements, thereby increasing the beam width of a beam which is in a high frequency band and has a high gain, so as to resist unsteadiness, such that the feed device has a certain anti-unsteady property in the high-frequency band, and can improve the availability of high-frequency and large-capacity links while retaining the alternate function of low-frequency links.
