Ground Plane Effect TI.15 may be mounted near a piece of ground plane. The ground plane changes the antenna radiation property. We have placed TI.15 in different near-ground scenarios and observe its radiation behaviors. Four different antenna placements were tested -1. Free Space 2. Small Ground (15 x 9cm) – common size of CPE devices. TI.15 is mounted at the longer edge for testing. 3. Big Ground Edge (45 x 30cm) – simulate the effect of mounting antenna on a base station device. TI.15 is mounted at the centre of the longer edge. 4. Big Ground Centre (45 x 30cm) – simulate the effect of mounting antenna in a centre of a big ground plane, such as vehicle top.
