<p>A microstrip antenna having a radiating conductor plate (11) and a grounding conductor plate (12) which are so disposed as to oppose each other. A metal plate (21) is disposed on the grounding conductor plate in the proximity of at least one edge in the resonance direction of the radiating conductor plate (11) so as to create an additional capacitance between the open end of the radiating conductor plate in the resonance direction and the grounding conductor plate, and thus to shorten the antenna length.</p> |
