Title:
MULTI-FREQUENCY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2016/173058
Kind Code:
A1
Abstract:
The present invention discloses a multi-frequency antenna, and is mainly applied to a field of wireless communications. The multi-frequency antenna comprises at least one set of radiating unit arrays, and each set of radiating unit arrays comprises at least one radiating unit array of a first type and at least one adjacent radiating unit array of a second type. Each radiating unit in the radiating unit array of the first type can at least separate frequency band F1 and frequency band F2, and a part of radiating units of the radiating unit array of the second type can at least separate frequency band F1 and frequency band F2. In each set of radiating unit arrays, a port for frequency band F1 of each radiating unit of the radiating unit array of the first type is connected to ports for frequency band F1 of the part of the radiating units of the radiating unit array of the second type via a power feeding network, and the power feeding network is connected to an output port for frequency band F1 of said set of the radiating unit array. The present invention has advantages of a simple layout and good isolation while satisfying a horizontal beamwidth standard for an output frequency band.
