<p>A thin, low-loss, and two-frequency slot array antenna which excites slot elements having different resonance frequencies through a common parallel-plate waveguide and radiates the same linearly polarized wave at different frequencies. The slot array antenna comprises the slot elements having different resonance frequencies and arranged on one conductor plate of the parallel-plate waveguide having short faces at both ends in such a way that the directions of the electric fields of the slot elements are perpendicular to the short faces.</p> |
