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.
