RF antennas are widely used in many applications, from communication and navigation to radar and medical sensing. An example of a common RF antenna is the OC572112, which is used in a variety of applications. This article discusses the common application fields and working principles of the OC572112 RF antenna.

Applications of OC572112

The OC572112 is a circularly polarized, half-wave dipole antenna. It operates in the Ku-band frequency range, from 11.45 GHz to 12.75 GHz. The antenna has a small form-factor of approximately 18 cm in diameter and is designed for applications with limited space. Common application fields include point-to-point and point-to-multipoint fixed wireless links, satellite communication links, and broadcast television receivers.

Due to its low profile and high gain, the OC572112 is an ideal choice for terrestrial links. It is often used in wireless microwave link applications, such as microwave path bridging, line-of-sight wireless links, and satellite communications links. Its high gain also makes it a good choice for broadcast television receivers. In addition, the antenna can be used for air-to-ground communications in aircrafts, enabling secure data transfer and communication.

Working Principle of OC572112

The working principle of the OC572112 is based on the principle of half-wave dipole antenna. A half-wave dipole antenna consists of two conductors, which are connected to the antenna’s feed. The electric field is perpendicular to the antenna’s length and the antenna radiates electromagnetic waves in the same direction as the feed line. The antenna is designed to have an output power of 0 dBm and has a gain of 17 dB.

The antenna operates in the Ku-band frequency range and exhibits an omnidirectional radiation pattern with a 3 dB beamwidth of 90 degrees. It has a low VSWR of 1.2:1. The antenna’s radiation pattern is uniform and its gain is maintained within a narrow bandwidth, allowing it to be used for narrowband applications such as satellite communication links.

The OC572112 is also equipped with a built-in phase shifter, which allows its user to manually adjust the antenna’s radiation pattern. The phase shifter can be used to reduce the antenna’s signal strength in one direction while increasing the signal strength in the opposite direction, thus allowing the user to shift the position of the antenna’s lobe. This is useful when the antenna is used in directional applications such as point-to-point links.

Conclusion

The OC572112 is a small form-factor circularly polarized RF antenna that is suitable for various applications. It operates in the Ku-band frequency range and has a gain of 17 dB. The antenna has a built-in phase shifter, allowing its user to manually adjust the radiation pattern. Common application fields include point-to-point and point-to-multipoint fixed wireless links, satellite communication links, and broadcast television receivers.
