A fixed-frequency dual-beam scanning microstrip leaky-wave antenna (MLWA) is presented in this letter. Through controlling the novel feeding configuration, MLWA has the advantage of dual-beam scanning at the fixed frequency. The main lobe scans from 41.16deg to 63.01deg for the right beam and from 116.75deg to 138.59deg for the left beam when operating frequency fixes at 7 GHz.
