RF Antennas

HDDA4W-28-DP antenna is part of the collection of radio frequency (RF) antennas. Its application field encompasses long-distance, high-gain wireless communication in a variety of areas such as telecom, aerospace applications, and broadcasting.

1. Application Field

Due to its high gain and a wide frequency range, the HDDA4W-28-DP antenna is often used for long-range wireless communication in many areas. These areas may include broadcast systems, long-distance data links, remote sensing systems as well as wireless backhaul. It is often used in aerospace applications as an uplink for communications to earth stations and as a downlink for earth-based tracking and control systems.

The HDDA4W-28-DP antenna has a wide frequency range and a high gain combination, allowing it to be used in a variety of wireless communication environments. It is suitable for applications such as satellite communications, deep space tracking, airborne radar, satellite-to-satellite communication, point-to-point data link systems, public safety and military communication systems. It is widely used in both ground and airborne platforms where a reliable and stable signal reception is essential.

2. Working Principle

The working principle of the HDDA4W-28-DP antenna is based on the concept of antenna radiation patterns. This antenna utilizes a directional radiation pattern in the horizontal and vertical planes, providing a high gain output with a wide frequency range from 400 MHz to 2000 MHz. The antenna is also capable of providing a minimum of 10 dB gain in the vertical plane and at least 3 dB in the horizontal plane.

The antenna is composed of two elements: a transmitting element and a receiving element. The transmitting element consists of two waveguides that are located at the front of the antenna. The receiving element is located at the back of the antenna and is composed of two dipoles. Both elements are centered on the antenna’s axis and oriented in opposite directions, forming an omni-directional pattern.

The two elements interact with each other, creating a standing wave between them. This standing wave reflects the electromagnetic signals that are transmitted from the transmitting element and then absorbed by the receiving element. As the signals are absorbed, they are amplified and in turn, transmitted back to the source.

Conclusion

The HDDA4W-28-DP antenna is part of the RF antennas family and is used in a variety of applications for wireless communication. Its application field includes long-distance, high-gain wireless communication while its working principle is based on the concept of antenna radiation patterns. The HDDA4W-28-DP antenna can help in providing a reliable and stable signal reception that is essential for various applications.
