TI.08.A.0111 Datasheet, PDF (7/11 Pages) Taoglas antenna solutions – High radiation efficiency and robust handling

V. 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.
