Wireless communication device
View Patent ↗Provided is a wireless communication device that ensures reduced interference between a plurality of antennas without relatively separating the antennas. The wireless communication device includes a first antenna, a second antenna, and a planar conductor. The conductor is arranged adjacent to both of the first and second antennas on one side. A cutout portion is formed in the conductor. The cutout portion extends from an outer edge between positions adjacent to the first and second antennas.
1. A wireless communication device, comprising:
a first antenna that is elongate and extends in a first longitudinal direction;
a second antenna that is elongate and extends in a second longitudinal direction; and
a planar conductor arranged laterally adjacent to both of the first and second antennas on one side, thereby defining a first area of the planar conductor adjacent to the first antenna and a second area of the planar conductor adjacent to the second antenna,
wherein the planar conductor includes a first cutout portion that extends from an outer edge thereof in a transverse direction with respect to the first and second longitudinal directions, such that the first cutout portion extends between the first and second areas.
2. The wireless communication device of claim 1 , wherein the length of the first cutout portion is variable.
3. The wireless communication device of claim 1 , wherein the planar conductor is arranged to overlap the first and second antennas as seen from a side face.
4. The wireless communication device of claim 1 , wherein the respective first and second areas of the planar conductor at positions adjacent to the first and second antennas are thicker than other areas.
5. The wireless communication device of claim 1 , further comprising: a board connected to the first and second antennas, wherein the board includes a second cutout portion extending from an outer edge of the board and passing between a position to which the first antenna is connected and a position to which the second antenna is connected.
6. The wireless communication device of claim 1 , wherein the planar conductor is bonded to a board made of a dielectric.
7. The wireless communication device of claim 1 , wherein the planar conductor is bonded to a board that incorporates circuit elements making up electronic circuitry.
8. A wireless communication device, comprising:
a first antenna;
a second antenna;
a board to which the first and second antennas are connected, the board including a first cutout portion extending from an outer edge of the board and passing between respective positions at which the first and second antennas are connected to the board, respectively; and
a planar conductor arranged adjacent to both of the first and second antennas, and including a second cutout portion that extends from an outer edge between positions adjacent to the first and second antennas.
