A dual-polarized standard horn antenna adopts rectangular or square waveguide feeding with a pyramidal standard horn aperture. Built-in orthogonal dual feeds and an OMT structure enable horizontal and vertical (H/V) dual linear polarization. It features a standardized structure, moderate bandwidth, high port isolation, symmetrical radiation pattern and low cost.
Typical Structure (Pyramidal Dual-Polarized Standard Horn)
Feed Section: Square or rectangular waveguide, integrated with orthogonal dual probes or cross-diaphragm OMT, equipped with two independent 50Ω ports in N / SMA / 2.92mm interface.
Transition Section: Short linearly tapered pyramidal section, ensuring balanced transmission of TE10 / TE01 modes and suppressing higher-order modes.
Radiation Section: Standard rectangular aperture with symmetrical E-plane and H-plane tapering, delivering circularly symmetric pattern and low sidelobe performance.
Key Difference
No ridged structure is adopted. Dual polarization is realized by waveguide orthogonal modes and symmetrical aperture design. It owns a simpler mechanical configuration and higher power handling capacity.
