7.2 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT LOCATIONS WITH
VERTICAL PLANE GROUND FOR CONFIGURE 1 AND CONFIGURE 2
Four locations with vertical plane ground have been evaluated and the location presentation is
shown in figure 7.2. The plane ground size is 60*30mm and we move the plane ground to four
locations for each test.
The distance between antenna and vertical plane ground affect the antenna performance slightly.
The minimum distance between antenna and plane ground is recommended to be 10mm to
achieve acceptable RF performance for configure 1.
The minimum distance between antenna and plane ground is recommended to be 5mm to achieve
acceptable RF performance for configure 2.
FIGURE 7.2 FOUR LOCATIONS WITH VERTICAL PLANE GROUND (USING CONFIG1 FOR
ILLUSTRATION)
Ground Size: 60mm*30mm;
Location D1: Distance between antenna and plane ground is about 5mm;
Location D2: Distance between antenna and plane ground is about 10mm;
Location D3: Distance between antenna and plane ground is about 15mm;
Location D4: Distance between antenna and plane ground is about 20mm.
