Abstract
A microstrip meandering-line antenna for a wireless communications system includes a substrate, a meandering-line conductor, and a feeding wire. The substrate, which is made of a dielectric material or a magnetic material, has a first surface. The meandering-line conductor is attached to the first surface in a reciprocating bent manner for receiving radio signals, and the meandering-line conductor has a mid-point connection between two ends of the meandering-line conductor. The feeding wire is electrically connected to the mid-point of the meandering-line conductor for transmitting a received radio signal to the wireless communications system.
