6.0 PERFORMANCE AS A FUNCTION OF IMPLEMENTATION
6.1 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT LOCATIONS WITH
PARALLEL PLANE GROUND
Four locations with parallel plane ground have been evaluated and these locations are shown in
figure 6.1.0. The plane ground size is 90mm*90mm and we move the plane ground to four locations
for each test. The antenna performance is better with larger distance between antenna and parallel
plane ground at high band. The minimum distance between antenna and plane ground is
recommended to be 15mm to achieve acceptable RF performance.
FIGURE 6.1.0 FOUR LOCATIONS WITH PARALLEL PLANE GROUND
Ground Size: 90mm*90mm;
Location 1: Distance between antenna and plane (GAP) ground is about 5mm;
Location 2: Distance between antenna and plane (GAP) ground is about 10mm;
Location 3: Distance between antenna and plane (GAP) ground is about 15mm;
Location 4: Distance between antenna and plane (GAP) ground is about 20mm.
