The TC93474 Horn Antenna is Quad ridged horn antenna which save users time from rotating standard EMC antennas when switching polarizations. Utilizing a RF switch and software, swapping between vertical and horizontal testing saves time and ensure measurements from the same point of axis. High frequency quad ridge horn antennas, TC93474, are also utilized in 5G, OTA and antenna pattern measurement testing due to those advantages.
Further, the new coaxial line to Quad Ridged waveguide transition and a new technique for tapering the flared section of the horn was introduced to improve the return loss and matching of the impedance. With this in mind, the TC9374A Horn Antenna offers very good VSWR, isolation and gain over an ultra wide band of frequencies making it essential for 5G mmWave testing applications.
Why the TC-93474A Horn Antenna?
The TC-93474 Horn Antenna at the transmitter side transmit radio waves from a waveguide out into space and at the receiver side it collects radio waves into a waveguide. The horn antenna seems to be a waveguide that has been widened out in the form of a horn. As a result, it finds many applications in areas where waveguides are used. To improve the radiation efficiency and directivity of the beam, the wave guide is provided with an extended aperture. This extended aperture makes the abrupt discontinuity of the wave into a gradual transformation, so that all the energy in the forward direction gets radiated. This can be termed as Flaring. This is done using a horn antenna. When the waveguide is terminated by a horn, impedance matching is obtained due to this smooth transformation.
The energy of the beam when slowly transform into radiation, the losses are reduced and the focusing of the beam improves. A Horn antenna may be considered as a flared-out wave guide, by which the directivity is improved, and the diffraction is reduced.
When radio waves travelling through the waveguide hit the opening only a small portion of the energy will be reflected. This happens because of mismatch at the end of the waveguide with space.
