PROBLEM TO BE SOLVED: To improve a transmission/reception gain of radio equipment at a communication frequency.SOLUTION: A radio communication device comprises an antenna 300, an IC 105 connected to the antenna 300 and a metal member 400 having a surface 400A and disposed to face the antenna 300. The antenna 300 includes: a ground conductor 320; an antenna element 310 having one end 310A open and the other end 310B connected to the ground conductor 320; and a signal line 330 having one end 330A connected to the IC 105 and the other end 330B connected between the one end 310A and the other end 310B of the antenna element 310. On the surface 400A of the metal member 400, there is formed a recess 402 which overlaps with at least a part of the signal line 330, when viewed in a -Z direction from the antenna 300 side toward the metal member 400 side.SELECTED DRAWING: Figure 2 |
