Abstract

A low cross-polarization slab waveguide filter for narrow-wall slotted waveguide array antenna with high gain horn is presented. In narrow-wall slotted waveguide array, the horizontal polarization (HP) is the co-polarization, while the vertical polarization (VP) is the cross-polarization. Slotted waveguide array is widely used in radar system, and the high level cross polarization reflects the effect of radar antenna. Physical formulas were presented to give a concise explanation how this structure reduces cross-polarization. The gain of only waveguide slotted array antenna is not high enough for radar system. On this basis, a 40-element low cross-polarization narrow-wall slotted waveguide array antenna with high gain horn in 9.305GHz was designed and simulated. The antenna has the characteristics of SLL=-30dB, cross-polarization lower than -40dB and gain=32dB in main lobe.
