Introduction
RF antennas are an essential part of any radio communication system. They are used to receive and transmit electromagnetic waves in the radio frequency (RF) range. One type of RF antenna that is widely used is the EXB221TN antenna. This antenna has a wide range of applications and is useful for a variety of wireless communication systems. In this article, we will discuss the application field and working principle of the EXB221TN antenna.Application Field
The EXB221TN is a wideband directional antenna that can be used in various applications. It can be used for point-to-point link, base station, repeaters, portable or mobile applications. It is ideal for wireless local area networks (WLANs) such as 802.11a/b/g/n and 802.16 WiMAX band. It is used in various frequencies ranging from 2.4GHz to 5.8GHz.This antenna is also used for other communications systems such as Global System for Mobile (GSM) and Bluetooth installations. The antenna has a low-VSWR and is waterproof. Besides, it has a durable construction and is resistant to high winds and other environmental conditions.Working Principle
The EXB221TN is a type of directional antenna known as a yagi antenna. It consists of a linear array of driven elements that produce a directional radiation pattern. The number and arrangement of the elements determine the angular radiation pattern of the antenna. The antenna is connected to a feedline, which connects the antenna to a radio transceiver. The feedline carries the radio signals and boosts the signal strength. When the radio signals reach the antenna, the driven elements resonate with the incoming signals. This creates voltage along the metal parts of the antenna, which are called conductors. The voltage makes the electromagnetic waves propagate along and outside the antenna in a particular direction. This is known as directional radiation pattern.The antenna has a gain that is determined by the arrangement of the driven elements. It is measured in decibels (dB). The antenna has a high gain, which means it can send signals farther with less power than other types of antennas.Conclusion
The EXB221TN antenna is a type of directional antenna that is suitable for various wireless communication systems, including WLANs, 802.16 WiMAX, GSM, and Bluetooth installations. It consists of a linear array of driven elements that produce a directional radiation pattern. The antenna is connected to a feedline that carries the radio signals and boosts the signal strength. Additionally, it has a high gain, which means it can send signals farther with less power than other types of antennas.
