SPE-16-8-002/A/SS Page 12 of 19 6. Installation 2.4GHz remote control receivers usually need two separate 2.4GHz receiver antennas for receive diversity. Our antennas should be placed at both sides of the 2.4G remote receiver. Then the best RF signal condition can be obtained at any flying attitude. The antennas must be kept 15mm away from metal materials.
SPE-16-8-002/A/SS Page 13 of 19 Cable ties or adhesive can be used on the bottom of the filter jacket for the most reliable mounting solution. Ideally, the antenna is mounted close to the outer edge of the UAV device to allow it to radiate outwards and receive signals without obstruction from internal components in the device. In order to have best maximum antenna efficiency, it is suggested that the antenna is installed on plastic or fiberglass surfaces. Also it is important to keep the antennas away from the motor, ESC, and other electrical noise sources to reduce interference entering the receiver.
SPE-16-8-002/A/SS Page 14 of 19 7. Application Note 7.1 2 Port Isolation The antennas should be spaced at least 80mm apart to have minimum coupling interference, showing a similar return loss as in free space. Testing results for MIMO applications as follows: Test Set up 80mm Port 1 S11 Port 1 Port 2

SPE-16-8-002/A/SS Page 16 of 19 7.2 Ground Approximate Effects The Antenna needs to be at least 54mm away from a comparatively large metal surface to have similar return loss as in free space. In order to maintain good antenna performance, we suggest that a suitable distance to large metal planes are reserved. If the distance is smaller than 54mm, Taoglas can offer the fine tuning service to prepare custom antennas, subject to minimum order quantities. Test set up 54mm from Metal (Ground)
SPE-16-8-002/A/SS Page 17 of 19 7.3 Bending Angle on Antenna Main Body Due to the dipole antenna structure, cable routing of the antenna itself does not have much effect on performance. In real life scenarios however, the antenna matching and efficiency may be changed through bending the main body. The test setup and results below show the antennas response to bending. Test Set up @45°

The test setup and return loss in free space, on 2mm thick ABS plastic (a common plastic housing and material thickness), and also, in between two pieces of 2mm thick ABS plastic, are shown below. *Taoglas provides fine tuning service in order to get the best antenna performance in customer’s device.
