5.2 ANTENNA RF PERFORMANCES AS A FUNCTION OF DIFFERENT SIZED GROUNDS
5 kinds of ground plane size have been evaluated, and these configurations are show in figure
5.2.0. The figure 5.2.1-5.2.8 are shown the return loss, the efficiency, the peak gain and axial ratio.
The ground plane size for this antenna is recommended to be 70mm*70mm (reference size) to
meet the antenna specification.
(W*L:25mm*25mm、50mm*50mm、70mm*70mm、90mm*90mm、120mm*120mm)
