7.3 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT DISTANCES WITH
PARALLEL PLANE GROUND
Antenna performance will be degraded if the antenna is placed too close to a ground plane. Four
locations 5mm,10mm,15mm and 20mm from a parallel plane ground have been evaluated. These
locations are shown in figure 7.3.1. The plane ground size is 90mm*90mm. The antenna
performance is better with larger distance between the antenna and the parallel plane ground. The
minimum distance between the antenna and the plane ground is recommended to be at least
10mm to achieve acceptable RF performance.
