Document Type and Number:
WIPO Patent Application WO/2014/188747
Kind Code:
A1
Abstract:
A power feed pin (FP) of a radiation electrode is disposed in the vicinity of a first end in the lengthwise direction of a dielectric substrate. A ground pin (GP) of the radiation electrode is disposed in the vicinity of a second end in the lengthwise direction of the dielectric substrate. A first location (Z1) that is in the vicinity of the mid-point on the path from the power feed pin (FP) to the ground pin (GP) of the radiation electrode is close to a second location (Z2) that is a point midway from the first location (Z1) to the power feed pin (FP), or a third location (Z3) that is a point midway from the first location (Z1) to the ground pin (GP) is close to the first location (Z1). A capacitance-forming part (CC) is configured at a position where the second location (Z2) or third location (Z3) and the first location (Z1) are close to each other.
