GPST821/18503PTSM Application Field and Working Principle

This article gives an overview of the GPST821/18503PTSM series of RF antennas and their application field and working principle. GPST821/18503PTSM is part of a family of antennas designed to provide coverage for a variety of radio frequency (RF) applications. It is primarily used in the communication of signals between two places in the radio frequency spectrum, such as between a transmitter and receiver, or for broadcasting signals, or for the wireless control of electrical appliances.

Application Field

The GPST821/18503PTSM series of antennas is designed to offer a cost-effective solution for communications between two locations in the RF spectrum. Its most common applications are in data links, telemetry, air traffic control systems, and voice communications. The antenna design provides excellent radiation performance, low noise floor, great antenna gain, good stability, and wide bandwidths.

The GPST821/18503PTSM can also be used as a beacon antenna. This enables a radio station to inform its operators of its location, broadcast weather and alert messages, or to inform of other important notifications. This is of particular use in remote and hazardous areas where it is difficult to track down radio stations through conventional means. The antenna also works great at close range, such being used in perimeter protection and security applications at airports and military installations.

In addition, the GPST821/18503PTSM can be used for automotive purposes such as keyless entry systems and automatic locking systems. This is very useful in securing vehicles from unauthorized access and theft.

Working Principle

The GPST821/18503PTSM antenna is a type of monopole antenna. Monopole antennas consist of two vertical elements called the “feeder” and the “radiator”. The feeder is typically made of a low-loss material to help reduce the noise floor and maintain high fidelity. The feeder sends electromagnetic radiation from the receiver to the radiator. The radiation is then transferred from the radiator into the air via electromagnetic waves.

The GPST821/18503PTSM operates on a frequency range of between 821MHz and 18503MHz. To ensure maximum gain, the antenna is designed to have a low noise figure of less than 1.0 dB. This results in improved reception capability and better data link reliability.

The antenna can be mounted in different positions, for example, pointing upwards or downwards depending on the application for which it is being used. Generally, pointing the GPST821/18503PTSM towards the transmitter will reduce any interference from other sources.

Conclusion

The GPST821/18503PTSM series is a powerful and versatile antenna that can be used for a wide range of applications. It is highly efficient in sending and receiving RF signals, offering excellent radiation performance, superior gain, broad bandwidths, and low noise floor. It is ideal for both long and short range applications, making it a great choice for data links, telemetry, air traffic control systems, and many other radio frequency applications.
