Embodiment Construction
[0063] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0064] figure 1 The circuit board 4 and the antenna of the first embodiment are shown in a schematic perspective view. The antenna 1, for example as figure 2 As shown in the plan view of , it is applicable to a data communication device or the like including a circuit board 4 . A ground plane 5 is formed on the surface of the circuit board 4 . in addition, figure 1 , figure 2 The horizontal direction (the direction in which the ground plane 5 is formed) is shown as x-axis and y-axis orthogonal to each other, and the direction perpendicular to the x-axis and y-axis is shown as z-axis.
[0065] The antenna 1 has a plate-shaped radiating element 2 arranged on a ground plane 5 at a distance from the ground plane 5 . A power supply unit 3 connected to a power supply circuit (not shown) and a pair of short-circuit units 7 and 8 are provided on the peripheral portion...
