Summary of the invention
The objective of the invention is that the broadband is narrow in the Wi-Fi/WiMAX communication network, loss is big in order to overcome prior art, the low deficiency that gains provides a kind of butterfly oscillator array antenna.
In order to achieve the above object, technical scheme of the present invention is following:
Butterfly oscillator array antenna comprises little belt substrate, impedance transformer network unit, radiating element, distributing point, radiating layer; Three radiating elements connect to form first order array through the impedance transformer network unit; Four first order arrays connect to form second level array through the impedance transformer network unit; Two second level arrays connect to form radiating layer through the impedance transformer network unit; Its impedance transformer network unit center point is as distributing point, and radiating layer adheres on little belt substrate.
Described radiating element be shaped as butterfly.The angle of the adjacent radiation unit of described first order array is 120 degree.
The present invention has bandwidth, and gain is high, and loss is low, and cost is low, and radiation characteristic is good, and is simple in structure, is easy to make, and satisfies the requirement of Wi-Fi/WiMAX communication network.
