Abstract
Presented is a multi-band antenna module in which antennas having different polarization characteristics are coupled to prevent deterioration in isolation caused by interference between the antennas. The presented multi-band antenna module comprises: a patch antenna for transmitting/receiving a signal of a first frequency band; and a circuit board which has the patch antenna mounted on the top surface thereof, and which has a conductor pattern for transmitting/receiving a signal of a second frequency band while feeding the patch antenna.
Claims17
A multi-band antenna module comprising:
- a circuit board;
- and
- a patch antenna disposed on an upper surface of the circuit board and configured to transmit or receive a signal having a first frequency band,
- wherein a first conductor pattern that transmits or receives a signal having a second frequency band while feeding power to the patch antenna is formed in the circuit board,
- wherein a first area that is an area in which the patch antenna is mounted, a second area that is remaining areas except the first area, and a clearance area that is an area covering the first area and the second area are defined on at least one surface of the upper surface and the lower surface of the circuit board, and
- wherein the first conductor pattern is formed as an island pattern that is formed to be isolated from an outer circumference of the clearance area within the clearance area.
