Abstract
An antenna device is disclosed. An antenna such as a dipole antenna and a parallel feeder each formed of a conductor pattern are disposed on a dielectric plate. The connector is connected to the antenna through the parallel feeder. The parallel feeder has a length of an integral multiple of a half wavelength and has an even number of bending points between the connector and the antenna.
Claims3
An antenna device, comprising:
- a dielectric plate;
- an antenna formed of a conductor pattern and disposed on the dielectric plate;
