## **5. Ground Plane Effect** 

Three ground setups are used to see the affect of positioning TI.08 close to ground - 

1. Small Ground (15 x 9cm) – common size of CPE devices. TI.08 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. TI.08 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.
