TC-93474 Quad-Ridged Horn Antenna
The TC-93474 Quad-Ridged Horn Antenna helps engineers save time during EMC and high-frequency testing. Unlike standard EMC antennas, it removes the need to rotate the antenna when switching polarization. Instead, users switch between vertical and horizontal polarization using an RF switch and software.
As a result, engineers keep the same axis reference point during testing. This approach improves repeatability and speeds up measurements. Because of these benefits, engineers often use the TC-93474 for 5G, OTA, and antenna pattern measurements.
Designed for High-Frequency and 5G Testing
The TC-93474 uses an improved coaxial-to-quad-ridged waveguide transition. This updated design improves impedance matching and reduces return loss. In addition, a new flare-tapering method enhances overall RF performance.
Because of these improvements, the antenna delivers low VSWR, strong isolation, and consistent gain across an ultra-wide frequency range. These features make it a reliable choice for 5G mmWave testing applications.
How the TC-93474 Horn Antenna Works
On the transmit side, the horn antenna sends radio waves from the waveguide into free space. On the receive side, it collects radio waves and guides them back into the waveguide. The flared horn shape allows the waveguide to transition smoothly into open space.
This smooth transition improves impedance matching and reduces reflections. As a result, more energy radiates forward instead of reflecting back into the waveguide. Engineers refer to this gradual transition as flaring.
Because the antenna spreads the wave energy evenly, it improves beam focus and directivity. At the same time, it reduces diffraction and signal loss. These traits make horn antennas useful wherever waveguides operate.
