Abstract

PURPOSE:To reduce the interference between arrays, by providing the shield material made of plate or block having the shield effect of electromagnetic effect at the external of center power supply of waveguide having slot antenna array. CONSTITUTION:The energy of electromagnetic waves fed through the power supply line 1 is split equally left and right at the branch section 2 and is fed to the left and right arrays 3 and 4. A plurality of slot elements 5 are respectively provided to the arrays 3, 4, and electromagnetic waves are irradiated to space with the slot element 5 and synthesized. The shield member 7 is mounted so that it is adhered to the waveguide constituting the flare 6 and arrays 3, 4.
