Antenna device, preferably PIFA type, used for e.g. mobile phones, includes conductive plate containing two slots with capacitive loads

摘要

The conductive plate (11) covering an earth plane is provided with two slots (18, 19), each with a capacitive load. An Independent claim is also included for a method of making single, double or multi-band antennae, preferably of the PIFA (planar inverted F-antenna) type with the above design.
