【Single-polarized Slotted Waveguide Array Antenna Manufacturer | Dolph Microwave】X-band Weather Radar Slotted Waveguide Array Antenna

The narrow-side oblique slit traveling slotted waveguide array antenna is designed to suppress cross-polarization through the dual design of choke groove and polarization grid. The product has the characteristics of high gain, low sidelobe, wide scanning angle and low cross-polarization.

DH-SWRAX04-64-LPS-SMA is a weather resistant X-band slotted waveguide array antenna that operates from 8.2 to 12.5 GHz. The antenna offers 39 dBi nominal gain and a typical half power beamwidth of 1.6°*(1±10%) degrees, respectively. Compared to microstrip antennas, the slotted waveguide array antenna offers higher aperture efficiency. The antenna also offers typical side lobes of -25 dB or better and cross polarization: ≤-30dB, supports linear, vertical polarized waveforms. The input of this antenna is a SMA-K.
