Embodiment Construction

[0013] refer to figure 1 , which is an array antenna 100 showing an embodiment of the present invention, including a first antenna unit 101 , a second antenna unit 102 , a third antenna unit 103 and a fourth antenna unit 104 . The first antenna unit 101 , the second antenna unit 102 , the third antenna unit 103 and the fourth antenna unit 104 are all antenna structures with an L-shaped cross section. The second antenna unit 102 is adjacent to the first antenna unit 101 . The third antenna unit 103 is adjacent to the second antenna unit 102 and opposite to the first antenna unit 101 . The fourth antenna unit 104 is adjacent to the third antenna unit 103 and the first antenna unit 101 .

[0014] The following takes the first antenna unit 101 as an example to describe the detailed structure of each antenna unit, wherein the first antenna unit 101, the second antenna unit 102, the third antenna unit 103 and the fourth antenna unit 104 have the same structure , so it will not be...

Abstract

The invention relates to an array antenna which comprises a first antenna unit, a second antenna unit, a third antenna unit and a fourth antenna unit, wherein the second antenna unit is adjacent to the first antenna unit; the third antenna unit is adjacent to the second antenna unit; and the fourth antenna unit is adjacent to the third antenna unit and the first antenna unit and is opposite to the second antenna unit.

Description

technical field [0001] The present invention relates to an array antenna, in particular to an omnidirectional array antenna. Background technique [0002] Known antennas generally use omnidirectional dipole antennas in order to cover all surrounding areas. However, the gain of dipole antennas is not high and the transmission distance is limited. To improve the gain of a dipole antenna, its size needs to be increased. Taking a dipole antenna with a gain of 11dBi in the 0.8GHz frequency band as an example, its size must be at least 300 cm. [0003] The known technologies also include microstrip antennas disclosed in US Patent Publication No. 20060273865 and US Patent Publication No. 7,173,572. The combination requires a jig or a support frame to complete, and the cost is relatively high, and the volume is still relatively large. Contents of the invention [0004] The present invention provides an array antenna for solving the problems of the known technology, including a f...
