6.4 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT CABLE LENGTH
Six cable length have been evaluated. The cable length is 50mm, 100mm, 150mm (reference
metal), 200mm 250mm and 300mm. these states are shown in figure 6.4.
The cable length should be more than 100mm. The resonance frequency shift to lower and the
antenna performance will decrease obviously at 824-960MHz band when the cable length is
less than 100mm.
