RF antennas are an essential part of many electronic systems. There are a variety of antenna types available, with each type specialized for specific applications. One type of antenna available is the EXC470BN, a broadband antenna designed for efficient 4G LTE operation. Here, we will discuss the applications and working principles of the EXC470BN antenna.

Applications

The EXC470BN is specifically designed for 4G LTE systems operating in the 698-960/1710-2700MHz frequency range, meaning it can be used in most parts of the world. It is perfect for those applications requiring wide-band coverage, such as cellular base stations. The antenna is also well suited for mobile applications, thanks to its low profile and efficient performance in a small form factor.

Another application for the EXC470BN is in IoT (Internet of Things) systems. This is due to its ability to support both uplink and downlink communications. The antenna is compatible with most routers, making it a great choice for wireless networks and providing high-speed connections for remote access.

Working Principle

The EXC470BN utilizes a strong internal magnetorheological fluid that allows it to rapidly adjust its electrical characteristics. This manifests as a wide frequency range of 698MHz to 2700MHz, allowing for high efficiency operation. It also allows the antenna to be used in multiple different orientation, such as horizontal, vertical, and circular polarization.

The antenna utilizes a folded dipole design, which works to capture more signal than a straight dipole design with the same size. This allows the EXC470BN to work effectively in crowded metropolitan areas, where there is lots of interference from other antennas. The folded dipole design also makes the antenna more efficient, as it reduces the impedance mismatch between the antenna and the transmission line.

The antenna’s gain of around 7 dBi makes it a great choice for cellular or IoT systems. This gain is efficently maintained across different frequencies. This is thanks to the strong magnetorheological fluid that allows it to rapidly adjust its electrical characteristics.

Conclusion

The EXC470BN is a great choice for widespread or mobile applications. It is specifically designed for 4G LTE operation and supports frequencies ranging from 698 MHz to 2700 MHz. It also has a great gain of around 7 dBi and is highly efficient across different frequencies. This makes it an ideal choice for cellular or IoT systems.
