ANTENNA HAVING 4 PIFA ANTENNA

摘要

The present invention relates to an antenna structure consisting of four planar inverted F antennas (PIFA) and, more specifically, to an antenna structure consisting of four PIFA mounted as linear polarization or circular polarization according to a phase change between feeders and capable of easily changing the direction of a beam by installing a plurality of PIFA on transmission line in a lattice shape. The present invention is constituted of the PIFA, the PIFA are installed on the transmission line in a lattice shape, and the antenna structure is mounted as the linear polarization or circular polarization according to the phase change between the feeders and can easily change the direction of a beam.
