Slotted antenna arrays used with waveguides are a popular antenna in navigation, radar and other high-frequency systems. The waveguide array antennas are simple to fabricate, have low loss (high antenna efficiency) and radiate linear polarization with low cross-polarization. The narrow-side oblique slit travelling slotted waveguide array antenna is designed to suppress cross-polarization through the dual design of the choke groove and polarization grid. The product has the characteristics of high gain, low sidelobe, wide scanning angle and low cross-polarization. Taking X-band slotted waveguide array antenna with model DH-SWRAX04-128-LPD-BMA as the example below.
