Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] A 16-element microstrip array antenna with equal power and rotating feed of the present invention, the 16-element microstrip antenna array borrows the microstrip deployment branch, and realizes the power equalization and double sequence of the four antenna array elements through the central feed network The rotating feed structure can make the entire antenna (that is, the 16-element microstrip array antenna) have the same or better impedance and circular polarization characteristics as the antenna array unit, and the power equalization double sequential rotating feeding technology can eliminate the impedance mismatch, greatly improving circular polarization performance. It is equivalent to a "water pump", which pumps water from a low place to a high place. If the place to be pumped is high, multiple such "water pumps" can be placed in the middle. The ...

Abstract

The invention discloses a sixteen-unit micro-strip array antenna capable of carrying out power equal-division rotating feed. The sixteen-unit micro-strip array antenna capable of carrying out the power equal-division rotating feed is obtained in a copper coating configuration mode on a substrate, power is equally divided through a center feed network, four antenna array units are distributed, and the four antenna array units are arranged in a double-sequence mode. Due to the fact that the design mode of double-sequence rotation of feed networks is adopted by the sixteen-unit micro-strip array antenna capable of carrying out the power equal-division rotating feed, directivity of the sixteen-unit micro-strip array antenna capable of carrying out the power equal-division rotating feed can be better, the whole sixteen-unit micro-strip array antenna capable of carrying out the power equal-division rotating feed and the antenna array units have the same impedance characteristic and the same circular polarization characteristic or a better impedance characteristic and a better circular polarization characteristic, and the sixteen-unit micro-strip array antenna capable of carrying out the power equal-division rotating feed is more applicable to a satellite communication system.

Description

technical field [0001] The invention relates to a 16-unit microstrip array antenna suitable for a wireless communication system, which is characterized by double sequential rotating feeds with equal power, works in the ka band, and has the characteristics of high gain and circular polarization. Background technique [0002] Currently, the radio spectrum is undoubtedly the most important strategic resource. The Ka band (27GHz~40GHz) is a part of the millimeter wave frequency band, and the millimeter wave wavelength is between microwave and infrared, so its characteristics are also between the two to a certain extent, with frequency bandwidth, short wavelength, and wear The characteristics of strong penetrating power, such as moderate resolution and good smoke and dust penetration, so in some cases it can complete tasks that are difficult for both microwave and infrared. Compared with microwave-band antennas, Ka-band antennas have the following advantages: (1) The beam is nar...
