TI183113 Datasheet, PDF (12/22 Pages) List of Unclassifed Manufacturers – 3dBi 868MHz ISM Band Dipole Terminal Antenna, SMA(M) Hinged Connector

5. Ground Plane Effect
Three ground setups are used to see the affect of positioning TI.18 close to
ground -
1. Small Ground (15 x 9cm) – common size of CPE devices. TI.18 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.18 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.
