FIELD: information technology. ^ SUBSTANCE: multiple antenna device has a printed circuit board having a grounding plate which can provide electromagnetic insulation between the first side of the printed circuit board and the second side of the printed circuit board; a first non-conducting bearing element formed n the first side of the printed circuit board; a second non-conducting bearing element formed on the second side of the printed circuit board; a first antenna formed on the first non-conducting bearing element; and a second antenna formed on the second non-conducting bearing element. The first antenna is electrically connected to a first feed point on the first part of the printed circuit board which is not connected to the grounding plate. The second antenna is electrically connected to a second feed point on the second part of the printed circuit board which is not connected to the grounding plate. ^ EFFECT: less electromagnetic coupling and high directivity. ^ 21 cl, 10 dwg |
