6.3 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT DISTANCES WITH
PARALLEL PLANE GROUND
Four locations with the parallel plane ground have been evaluated and these locations are shown
in figure 6.3.0. The plane ground size is 90mm*90mm and we move the plane ground to four
locations for each test. The distance between the antenna and the parallel plane ground affect the
antenna performance slightly. We still suggest the minimum distance between the antenna and the
plane ground is recommended to be 5mm.
FIGURE 6.3.0 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.
