摘要:
The invention provides an antenna that uses a complex structure in which a dielectric having a low dielectric constant and a magnetic substance having high magnetic permeability are arranged perpendicularly and periodically to improve the gain, efficiency, and bandwidth of the antenna while maintaining the miniaturization of the antenna which is an advantage of known antennas using a dielectric having a high dielectric constant. For this purpose, the provided antenna is characterized by including a substrate and a radiation patch formed on the substrate. The substrate is formed with a complex structure having a perpendicular period between the dielectric and the magnetic substance.
