Abstract
This disclosure presents a multiband patch antenna which resonates in a second frequency band as well as in a first frequency band, i.e., a GNSS frequency band, by adding an antenna pin to a patch antenna. The presented multiband patch antenna includes a base substrate, an upper patch disposed on an upper surface of the base substrate, a lower patch disposed on a lower surface of the base substrate, a feed pin which passes through the base substrate, the upper patch, and the lower patch, and an antenna pin which is spaced apart from the feed pin and passes through the base substrate and the lower patch.
Claims11
A multiband patch antenna comprising:
- a base substrate;
- an upper patch disposed on an upper surface of the base substrate;
- a lower patch disposed on a lower surface of the base substrate;
- a feed pin which passes through the base substrate, the upper patch, and the lower patch;
- an antenna pin which is spaced apart from the feed pin and passes through the base substrate and the lower patch to operate as a second antenna that resonates in a frequency band different from a frequency band of the upper patch;
- and
- an inner conductor disposed on an inner wall surface of a through-hole passed by the antenna pin to prevent deterioration of the isolation between the upper patch and the antenna pin,
- wherein the antenna pin passes through the base substrate in a second region of the upper surface of the base substrate where the upper patch is not disposed.
