RF antennas are a form of antenna structure that is designed and tuned to have resonance at radio frequencies, and they can be used to efficiently transmit or receive radio waves. The EXD450BNX is a popular UHF antenna used for broadband wireless applications such as cellular phone, trunking, and point-to-point communication. In this article, we will take a look at the application fields and working principle of the EXD450BNX antenna.

Application Field of EXD450BNX

The EXD450BNX antenna is a broadband UHF antenna designed for continuous coverage from 415-470 MHz and 450-520 MHz. It is most commonly used for applications such as cellular phone, trunking, and point-to-point communication. The antenna has a total gain of up to 9.7 dBi, making it a good choice for applications that require high gain and wide coverage. It is also directional, making it well suited for point-to-point and point-to-multipoint communications. Its low windload and compact design make it ideal for outdoor applications in remote areas.

Working Principle of EXD450BNX

The EXD450BNX is a broadband UHF antenna that operates on the principle of electromagnetic radiation. The antenna consists of two elements, an "exciter" section and a radiation section. The exciter section consists of a radiating element, driven by a coaxial line. The radiation section consists of a reflector and two directors. The incoming radio waves are received by the driven element, and the reflected and directed radio waves are then propagated inwards and outwards to the far field.

The EXD450BNX antenna is designed to be highly directional, with its maximum gain in the narrow beamwidth of up to 40°. This means that the antenna has the ability to focus the transmitted and received signals in a defined area. The antenna is also designed to provide low side lobes, which ensures minimal interference to signals in the surrounding environment.

Conclusion

The EXD450BNX is a popular UHF antenna used for applications such as cellular phone, trunking, and point-to-point communication. It is a broadband antenna operating on the principle of electromagnetic radiation, and it has a maximum gain of up to 9.7 dBi. The antenna is highly directional, with a narrow beamwidth of up to 40°. It is an ideal choice for applications that require wide coverage without interference from surrounding signals.
