Problems solved by technology

The existing antenna TRP (Total Radiated Power, total radiated power) evaluation method is mainly used to evaluate the emission performance of isodirectional antennas (that is, omnidirectional antennas). However, with the rapid development of the communication field, directional antennas have been It is gradually applied in satellite communication and some directional communications. Due to the strong directivity of the antenna direction of the directional antenna, the existing antenna TRP evaluation method is no longer suitable for evaluating the emission performance of the directional antenna.

Embodiment 1

[0047] see figure 1 The flow chart of a method for evaluating the emission performance of a directional antenna includes the following steps:

[0048] Step S102, detecting the power test value of the directional antenna to be tested at each test position; the azimuth angle and / or inclination angle of different test positions are different.

[0049] The anechoic turntable in the OTA test system can move the directional antenna to different Theta angles (ie tilt angles) and Phi angles (ie azimuth angles) in sequence. The azimuth angles and / or tilt angles of different test positions are different. It is necessary to measure the power test value of the directional antenna at each location, and record the results. For example, when testing a directional antenna, it is assumed that the Theta angle is set from 0 degrees to 180 degrees, and each 30 degrees is a step length of 6 steps; the Phi angle is from 0 degrees to 360 degrees, and each 30 degrees is a step length. , a total of ...
