GW152113 Datasheet, PDF (11/66 Pages) List of Unclassifed Manufacturers – 2.4GHz 2dBi Screw mount Dipole Antenna

5. Ground Plane Effect
Six ground setups are used to see the effect of positioning the GW.15 close to a ground plane.
1. Extra Small Ground (30mm x 30mm) – common size of Bluetooth devices
2. Small Ground (15 x 9cm) – common size of IoT devices. GW.15 is mounted at the
longer edge for testing.
3. Ground Edge (30cm x 30cm) – simulate the effect of mounting antenna on a
gateway/router.
4. Ground Centre (30cm x 30cm) – simulate the effect of mounting antenna in the centre
of a big ground plane.
5. Large Ground Edge (50cm x 50cm) - simulate the effect of mounting antenna on a large
gateway/router.
6. Large Ground Center (50cm x 50cm) - simulate the effect of mounting antenna in the
centre of a large ground plane e.g. vehicle body.
