APPLICATION SPECIFICATION 7.3 ANTENNA RF PERFORMANCE AS A FUNCTION OF LOCATIONS ON REFERENCE PCB FOR CONFIGURE 1 AND CONFIGURE 2 Two locations have been evaluated RF performance and these locations are shown in figure 7.3. Figure 7.3.1, figure 7.3.2, figure 7.3.3 and figure 7.3.4 comparatively present the return loss and efficiency at two locations. The performance of location 1 is much better than location 2. So the location 1 (upper center location) is the recommended location for this antenna. FIGURE 7.
