In this paper, a slotted waveguide antenna array at W band is proposed. The design procedure of the radiating element parameter extracting and the synthesis of planar array are introduced. A 9 × 9 slotted waveguide antenna array is designed and simulated. The results show that the Gain of the antenna is about 26.3dBi and the bandwidth is about 2.1GHz.
In this paper, a low sidelobe slotted waveguide monopulse antenna array working at Ka-band is proposed. The design procedure of radiating element parameter extraction and the synthesis of planar array is introduced. A 28 × 28 circular slotted waveguide antenna array is presented. The simulated bandwidth (return loss less than −20 dB) of antenna array is 1.48% and the corresponding isolations between...
In this letter, a dual-frequency dual-polarization slotted waveguide antenna array at Ka-band is proposed. A inclined slot array working at 35 GHz, cut in the narrow wall of rectangular waveguides, is employed for horizontal polarization (HP). An longitudinal slot array working at 30 GHz, etched on the broadside of ridged waveguides, is employed for vertical polarization (VP)...
