2.4G Yagi Antenna

Overview

Since the frequency used is 2.5G for 24R1 communication, the measurement parameters of the original antenna were not ideal, so they were improved. The actual test of the improved antenna was OK, so I would like to share it with everyone for testing and verification.

For the original antenna test parameters, see the comments below the original link.

In order to facilitate trimming of the newly made antenna, the antenna array was lengthened to 65.4mm, and the two following directors were increased by 16mm and 8mm. The test parameters were not ideal according to the drawings, so the extended directors were trimmed to 65.4mm according to the silk screen lines. The original same length, the data before and after trimming are attached later.

The picture below shows the actual effect of the antenna after trimming
