Abstract
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.
