RF antennas are essential for any kind of telecommunication and navigation system, as they are responsible for transmitting and receiving signals. The EXC400SMI is a popular antenna for two-way radio systems, which is reliable and has a wide range of frequency band. In this article, we will discuss the application field and working principle of the EXC400SMI antenna.

Application Field

The EXC400SMI antenna has a circularly polarized design, which makes it suitable for various applications. It is mostly used in radios used by the military, police, fire services or local government. It is also used in cellular networks, marine navigation, radio broadcasting, as well as applications in the medical and industrial fields. The frequency range of EXC400SMI is from 400 MHz to 2.4 GHz, and its integrated fastening make it compatible with almost all types of equipment. The standard polar diagram provided by the antenna makes it easy to plan any kind of installation.

Working Principle

The EXC400SMI antenna works on the principle of radiation from a directional dipole. This type of antenna has a vertical standing wave radiation pattern with an omni-directional beam pattern. It is also designed to minimize side lobe radiation in order to reduce interference. The dipole is fed with a high-frequency signal, which then radiates a signal in both the vertical and horizontal planes. The antenna is constructed from two λ/4 dipoles placed one in each plane. These dipoles are then connected in series, with the centre point of the dipoles providing the signal feed point.

The EXC400SMI antenna is connected to a transmission line, which helps to control the amplitude and phase of the radiation field. This helps to reduce the amount of interference, improve the antenna\'s working efficiency, and reduce any unwanted radiation in the far field. The antenna\'s design also helps to provide an excellent gain in both horizontal and vertical planes. This is important, as it allows the signal to be propagated over longer distances and in more varied conditions.

Conclusion

In conclusion, the EXC400SMI antenna is a reliable and well-built antenna that has a wide range of uses in various fields of telecommunication and navigation. The directional dipole design provides excellent gain in both vertical and horizontal planes, while the connection to the transmission line helps to reduce interference. The EXC400SMI is a versatile and reliable antenna that can be used in many applications.
