IV. Ground Plane Effect
Three ground setups are used to see the affect of positioning GW.71 close to ground -
1. Small Ground (15 x 9cm) – common size of CPE devices. GW.71 is mounted at the
longer edge for testing.
2. Big Ground Edge (45 x 30cm)
– simulate the effect of mounting antenna on a base
station device. GW.71 is mounted at the centre of the longer edge.
3. Big Ground Centre (45 x 30cm)
– simulate the effect of mounting antenna in a centre
of a big ground plane, such as vehicle top.
