A front feed microwave antenna, which comprises a radiation source, a first metamaterial panel used for radiating an electromagnetic wave emitted by the radiation source, a second metamaterial panel, and a reflective panel affixed to the back of the first metamaterial panel. The electromagnetic wave is emitted via the first metamaterial panel, refracted by entering the second metamaterial panel, reflected by the reflective panel, and finally re-refracted by reentering the second metamaterial panel, then finally parallel-emitted.
