7.0 RF PERFORMANCE AS A FUNCTION OF IMPLEMENTATION
7.1 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT LOCATIONS WITH
PARALLEL PLANE GROUND
Antenna performance will be degraded if the antenna is placed too close to a ground plane. Four
locations from 5mm, 10mm, 15mm and 20mm with a parallel plane ground have been evaluated.
The locations are shown in figure 7.1.1. The plane ground size is 90mm*90mm. The antenna
performance is better with larger distance between antenna and parallel plane ground. The
minimum distance between antenna and plane ground is recommended to be at least 15mm to
achieve acceptable RF performance.
