Title:
MULTI-FREQUENCY ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2014/082510
Kind Code:
A1
Abstract:
Disclosed is a multi-frequency array antenna, which comprises: a reflective metal plate, a low-frequency radiation column element which is arranged on the reflective metal plate and operating in a first frequency band range, and a high-frequency radiation column element operating in a second frequency band range. The low-frequency radiation column element comprises several low-frequency radiation units arranged at an equal first distance in the axial direction of a first reference axis. The high-frequency radiation column element comprises several high-frequency radiation units arranged at an equal second distance in the axial direction of the first reference axis. The first distance is 2.5 times the second distance. At least one of the low-frequency radiation units is nested with one high-frequency radiation unit locationally corresponding thereto, and at least one of the low-frequency radiation units is axially located between two adjacent high-frequency radiation units close to the low-frequency radiation unit. The present invention realizes the optimal setting of the distances between the radiation units of the low-frequency radiation column element and the high-frequency radiation column element, thereby realizing the optimization of the electrical performance in each frequency band.
