RF antennas are essential components of wireless communication systems. In most modern systems, antennas are designed to send and receive signals using radio frequency (RF). The HRN-0118 antenna is used in a wide range of settings and applications, from space communications to wireless healthcare. This article examines the working principle and application field of HRN-0118 antennas.

Overview of HRN-0118 Antennas

HRN-0118 antennas are highly-flexible antennas with a user-friendly design. This type of antenna is capable of transmitting and receiving radio frequency (RF) signals in the frequency range of 400 to 500 MHz. It has a circularly polarized gain of 14 dBi, a gain of 0.1 dB in far field, and a low axial ratio of 3 dB. It also supports a wide bandwidth from the low frequency range of 150 MHz to the high frequency range of 6 GHz. The antenna has a nominal cable length of 11 meters and a cable jacket diameter of 3.17 mm. In addition, its omnidirectional radiation pattern ensures equal coverage in both the horizontal and vertical planes.

Application Field of HRN-0118 Antennas

HRN-0118 antennas have wide application in various areas such as satellite communications, healthcare, and military uses. Its main application is the transmission and reception of wireless signals for satellite communication, such as satellite television (TV) broadcasting systems, mobile satellite services, earth observation satellites, and navigation aerospace systems. The HRN-0118 antennas are also used in medical instruments, including medical imaging scanners, devices for remote telemedicine systems, and radio-frequency identification (RFID) tags o detect patients in hospital beds, enabling quick responses to medical problems. Moreover, HRN-0118 antennas are used for military purposes, for instance, in anti-jamming applications and electronic warfare.

Working Principle of HRN-0118 Antennas

The working principle of HRN-0118 antennas is based on the principle of electromagnetic radiation. This type of antenna consists of two parts, an active element and a passive element. Each element has a purpose in the antenna’s operation. The active element is responsible for the actual wave transmission and is usually made from a conductive material, while the passive element absorbs the transmitted waves and directs their propagation.The active element of the HRN-0118 antenna is a conductor shaped in a certain geometry. This shape determines the antenna’s radiation pattern and polarization. The active element is connected to a feeder, which is either coaxial or waveguide, which is responsible for the modulation of the signal. The feeder transmits the signal to the active element, which is further amplified and made into a wave. The signal is then directed through the passive element, which reflects and radiates the wave. This signal is received at the receiver end, where it is amplified and demodulated.

Conclusion

In conclusion, HRN-0118 antennas are widely used in a variety of settings and applications. They are compact, flexible, and user-friendly. Their working principle is based on the principle of electromagnetic radiation, involving the use of an active element and a passive element. The active element is responsible for the actual wave transmission and the passive element directs and radiates the wave to its receiver. Therefore, HRN-0118 antennas are extremely valuable in satellite communications, healthcare, and military uses.
