摘要： It is an object of the invention to provide a meander antenna that is smaller and lighter, in which the resonance frequency easily can be tuned, as well as a method for tuning its resonance frequency. The meander antenna comprises a meandering conductor on the surface of a substrate. The meander antenna is provided with a short-circuit conductor line that forms a short-circuit between two parallel opposing lines into which the conductor is bent, or an open conductor line in which a line short-circuiting the two parallel opposing lines is open. The resonance frequency can be tuned and lowered by cutting open the short-circuit line or increased by short-circuiting the open conductor line.

摘要： In a surface-mount type antenna, a substantially-rectangular solid base body has a feeding terminal and a ground terminal formed on its one side surface. A radiating electrode has its one end connected to the ground terminal and is disposed helically across the surfaces of base body extending from one side surface to one principal surface. Another end of radiating electrode extends from one principal surface, through another side surface, toward another principal surface, to form a wide-area portion facing the feeding terminal. An antenna apparatus is constructed by mounting the surface-mount type antenna on a mounting substrate having formed thereon a feeding electrode, a ground electrode, and a ground conductor layer, and simultaneously connecting the feeding terminal and the ground terminal to the feeding electrode and the ground electrode, respectively.
