RF Antennas
An RF antenna, or radio frequency antenna, transmits and receives radio signals from an electronic device. Most commonly, RF antennas are used in wireless communications systems, such as cellular phones, two-way radios, broadcast television and radio, satellite communications, and wireless networks.
GD53-21 application field and working principle
The GD53-21 antenna is a multi-functional long-range, high-gain, versatile RF antenna. It is suitable for broadband applications within the 2GHz frequency band. The most common applications for the GD53-21 include providing wi-fi services, long-range cellular services, point to point communication, and linear polarization.
The working principle of the GD53-21 antenna is as follows; when an electrical signal is sent to the antenna, electrical current travels through the antenna in a turn motion and is changed to an electromagnetic field which radiates outward from the antenna in all directions. When the electromagnetic signal reaches an intended receiver, the receiver converts the signal back to an electric current and presents the original signal.
The GD53-21 antenna features high gain and a wide beamwidth which allows for long-range communications. The operating range of the antenna is -30 dB to 10 dB, and its engineered beamwidth of 64º-85°. It also has a low VSWR, typically below 1.5. which ensures optimum radiation efficiency. The antenna is also resistant to shock, vibration and extreme temperatures.
In addition to long-range communication, the GD53-21 antenna is also capable of linear polarization with polarization ratios of 20 dB or more in any polarization direction. This allows for narrow bandwidth communication. Finally, the antenna also has a low profile design that allows it to be installed in tight spaces and positioned in multiple directions for best signal coverage.
To conclude, the GD53-21 antenna is a multi-faceted, high-performance antenna suitable for a variety of broadcast and communication applications. It features a wide beamwidth, high gain, low VSWR, shock resistance and linear polarization capability for narrow bandwidth communication. With its low profile and versatile capabilities, the GD53-21 is ideal for both long-range applications and compact installations.
