M-shaped antenna apparatus provided with at least two M-shaped antenna elements |
摘要 |
An M-shaped antenna apparatus includes at least two M-shaped antenna elements, a grounding conductor, and a feeding portion. At least two M-shaped antenna elements includes first and second M-shaped antenna elements respectively having first and second resonance frequencies. The first M-shaped antenna element includes a first transmission conductor; a first radiation conductor connected between one end of the first transmission conductor and the grounding conductor; a second radiation conductor connected between a middle portion of the first transmission conductor and the feeding portion; and a third radiation conductor connected between the other end of the first transmission conductor and the grounding conductor. The second M-shaped antenna element includes a second transmission conductor, a fourth radiation conductor, a fifth radiation conductor, and a sixth radiation conductor in a manner similar to that of the first M-shaped antenna element.
