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. 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 grounding
has some influence on the low frequency performance of the antenna. We suggest the
minimum distance between the antenna and the plane ground is recommended to be 15mm.
FIGURE 6.3 FOUR LOCATIONS WITH PARALLEL PLANE GROUND
Ground Size: 90mm*90mm;
Location 1: Distance between antenna and plane ground (GAP) is about 5mm;
Location 2: Distance between antenna and plane ground (GAP) is about 10mm;
Location 3: Distance between antenna and plane ground (GAP) is about 15mm;
Location 4: Distance between antenna and plane ground (GAP) is about 20mm.
