ABSTRACT:
A coupled fed magnetic microstrip dipole antenna consisting of a thin eleically conducting, rectangular-shaped radiating element (resonator) and a nonradiating coupler formed on one surface of a dielectric substrate, the ground plane being on the opposite surface. The radiating element has one end shorted to the ground plane. There is only a single mode of oscillation. Oscillation takes place along the length of the radiating element, and the length determines the resonant frequency. The feed point is normally located at the end of the coupler; energy is in turn coupled to the radiating element. However, the feed point can be located along the uncoupled edge of the coupler. Input impedance matching is determined by a combination of the coupler length and the separation between the coupler and the radiating element, and also the feed location when fed along the uncoupled edge of the coupler.
