    摘要： Provided is a capacity loaded planar antenna with short stubs that can be brought to a small size and a low profile, achieves wider bandwidth, and can be tuned to multiple frequencies. A capacity loaded planar antenna with short stubs that has a simple structure and can be easily manufactured includes a base plate, an antenna element disposed so as to be parallel to the base plate, a plurality of short stubs that connect the antenna element to the base plate, and a side wall formed on the end of the base plate. The capacity loaded planar antenna achieves wider bandwidth with the small size and low profiled, can be tuned to multiple frequencies by adjusting the length of the short stubs, and uses plate-shaped foldable short stubs that are integrated with the antenna element.

    摘要： A normal mode helical antenna comprises a coil made by winding a first conductor helically, and a second conductor shorter than the first conductor having a feeding point at the middle thereof. The second conductor is disposed outside of the coil at a center part in a longitudinal direction thereof along the first conductor. Both ends of the second conductor are connected to the first conductor of the coil.
