Abstract
The present invention provides a broadband slot array antenna that can be implemented with lower cost by using a single dielectric layer and a metal layer, and makes easy to implement an active integrated antenna. The broadband slot antenna includes: a dielectric layer under which a microstrip feedline is formed; a ground formed on the dielectric layer and electromagnetically coupled with the microstrip antenna through a slot; and a reflection plane placed under the microstrip feedline in order to prevent board surface waves from being radiated and enhance antenna gain.
Claims5
A broadband slot antenna, comprising:
- a dielectric layer under which a microstrip feedline is formed;
- a ground formed on the dielectric layer and electromagnetically coupled with the microstrip antenna through a slot;
- and
- a reflection plane placed under the microstrip feedline in order to prevent board surface waves from being radiated and enhance antenna gain.
A slot array antenna, comprising broadband slot antennas,
- wherein each of the broadband slot antennas includes:
- a dielectric layer under which a microstrip feedline is formed;
- a ground formed on the dielectric layer and electromagnetically coupled with the microstrip antenna through a slot;
- and
- a reflection plane placed under the microstrip feedline in order to prevent board surface waves from being radiated and enhance antenna gain,
- wherein a baffle layer is formed on the ground conductor in order to prevent mutual coupling between the slot antennas and enhance antenna gain.
