摘要：

An ultrawideband double-ridge horn (DRH) antenna having a high gain and excellent impedance matching is presented. Two metal reflectors are perpendicular to the two ridges for improving the lower- and center-frequency gain, while two sets of metallic gird sidewalls are used to fix the two reflectors together for structural stability and further increase the lower frequency gain. Additionally, a fork-shaped dielectric plate, which is fixed between the ridges, is used to improve the higher frequency gain. To improve the impedance matching at 1-18 GHz, a microstrip line having a smoothly tapered ground plane is employed to feed the DRH antenna. Good impedance matching for VSWR < 1.85 and high gain ranging from 7.6 to 18.6 dBi are obtained for the designed DRH antenna.
