ANTENNA WITH COMPLEX STRUCTURE OF PERIODIC, GRATING ARRANGEMENT OF DIELECTRIC AND MAGNETIC SUBSTANCES

摘要

The present invention provides an antenna of a complex structure in which a dielectric material having low dielectric constant and a magnetic substance having high magnetic permeability are disposed in a periodic, grating arrangement. This improves the gain, efficiency and bandwidth of the antenna while maintaining miniaturization which is an advantage in conventional antennas using a dielectric having a high dielectric constant. The present invention comprises a substrate onto which a radiation patch is disposed. The substrate consists of double columns, where the bar shaped- dielectric and the magnetic substances are placed alternatively on each column, and the major axes of the dielectric and the magnetic substance are perpendicular to each other.
