Multilayer ceramic circular polarized antenna having a Stub parasitic element

摘要

The present invention forms a parasitic element on the top surface of a stacked dual ceramic dielectric and power supplied to the radiating element of a circular ring structure formed between the first ceramic dielectric and the second ceramic dielectric is formed between the radiating element and the parasitic element Power is induced in the parasitic element by the electromagnetic coupling by the high-permittivity second ceramic dielectric, thereby improving the broadband and gain of the antenna.A feeding part for supplying a double probe is formed on the lower surface of the dielectric substrate, and dual polarization of Left Hand Circular Polarization (LHCP) and Right Hand Circular Polarization (RHCP) And an open stub is formed at one side of the parasitic element so that the phase induced by the electromagnetic coupling is stabilized by the capacitive reactance.;
