Abstract
In a microstrip antenna device which has a radiating patch and a ground plate disposed opposite and in parallel to each other, a metal plate is provided on the ground plate in the vicinity of at least one of the opposite marginal edges of the radiating patch in the direction of resonance to form an added capacitance between an open end of the radiating patch in the direction of resonance and the ground plate, thereby permitting reduction of the antenna length.
