Title:
COMPOSITE ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/064682
Kind Code:
A1
Abstract:
When configuring a composite antenna device, it is contemplated that different antenna systems do not interfere with each other, and in an antenna in which a monopole antenna and a microstrip antenna that is a planer antenna are combined, no electric field is generated between conductors in the planar center of the microstrip antenna, and thus the monopole antenna is disposed by allowing a coaxial line to pass therethrough. In the present disclosure, a composite antenna device is obtained which comprises a resonance part, and thus reduces a leakage current from an outer conductor of the coaxial line even when the coaxial line is disposed outside the planar center of the microstrip antenna.
