ANTENNA APPARATUS HAVING TRANSMITARRAY FOR ANTENNA BEAM IMPROVEMENT IN WHICH RADIATION DETERIORATION FROM STACKED VOIDS IS OVERCOME

摘要

In an antenna apparatus, which has a transmitarray for antenna beam improvement in which radiation deterioration from stacked voids is overcome, the transmitarray of a metasurface is contactably attached onto a patch array antenna, the transmitarray of the meta surface serving as an electromagnetic wave lens, and a back cover such as a cell phone cover is contactably formed on the transmitarray, and thus, there is an effect that impedance matching and antenna gain are improved by the transmitarray. In the present invention, beamforming is possible not only in direct contact with a radiator, but also when the transmitarray and the cell phone cover are in contact, and thus, there is an effect that application to a thin planar structure of an electronic product is possible.
