Problems solved by technology

Traditionally, the Fries formula is used to calculate the transmit and receive loss of the free space antenna. The Fries formula itself does not include the polarization component. Some subsequent formulas consider the transmit and receive loss when the polarization of the transmit and receive antenna does not match, but these formulas are all assumptions Both transmit and receive antennas are single linearly polarized
However, the antennas used in practical engineering generally contain two polarization components, and there is a phase difference between the two polarization components. In this case, there is a lack of calculation and optimization methods

Embodiment 1

[0159] Calculate the transmission loss of 28GHz transceiver and two spatial relationships: 1. The two double-ridged horn antennas have a certain height difference. 2. The height of the two double-ridged horn antennas is the same.

[0160] From Figure 6 and Figure 7 It can be seen that the calculated value of the transmission loss considering dual polarization is larger than that of the traditional one without considering polarization, which is a common phenomenon. That is to say, if the case of dual polarization is not considered, the estimation of the transmission loss is relatively small.

Embodiment 2

[0162] Combined with the differential genetic algorithm, the maximum value of (28) and the antenna space phase position parameter corresponding to the maximum value can be obtained. The iterative result of a typical differential genetic algorithm is as follows: Figure 8 As shown, the calculation results without considering the polarization are used as reference values ​​for normalization.

Abstract

The invention relates to the technical field of an antenna transceiver, and provides an optimization method for an antenna transceiver device containing polarization parameters. Phases of two polarization components contained in a transceiver antenna are taken as dependent variables, and the phases include a spatial polarization angle and a time phase. Finally, a relational expression between transmission loss of the antenna transceiver and the dependent variables is obtained, and the phases of the transceiver antenna are optimized according to the relational expression to reduce the transmission loss of the transceiver antenna. The method solves defects that the antenna transmission loss obtained from antenna transmission calculation by using a traditional Friss formula is small. According to the method, a plurality of sets of transceiver antenna parameters which can achieve maximum receiving power can be obtained, and the antenna can be optimized according to the parameters.

Description

technical field [0001] The invention relates to the technical field of antenna transceiving, in particular to an optimization method of an antenna transceiving device including polarization parameters. Background technique [0002] The calculation of antenna transmission and reception loss is the core issue of radio science, and has important applications in the fields of radio wave propagation prediction, wireless communication system design, radar detection, radio measurement involving electromagnetic fields and antennas, electromagnetic interference and compatibility, etc. Traditionally, the Fries formula is used to calculate the transmit and receive loss of the free space antenna. The Fries formula itself does not include the polarization component.
