摘要：
This paper presents a dual band metal-only antenna that operates at 20/40GHz. The proposed metal-only antenna combines the functionalities of reflectarray and parabolic reflector antennas. The unit cell consists of a square waveguide with short circuit termination and a square metallic block in the center. At 20GHz, the reflected beam is determined by a parabolic surface. At 40GHz, the reflected beam is controlled by the phase distribution of cells in the antenna. The gain increases with frequency in the lower frequency band, which is similar to what happens in a parabolic reflector antenna. The aperture efficiency at 20/40GHz is about 22.99/43.79%.
