Benefits and Advantages
The major benefits and advantages of TG.22.0222 include:

• Multiband capability, allowing it to cover a wide range of frequencies from 700 MHz to 5.5 GHz.
• High directivity performance over a wide frequency range.
• Low profile design to reduce interference with other stationary objects.
• Compact design that takes up minimal space.
• High IP rating to protect against water and dust penetration.
• Fully designed, manufactured and tested for use indoors.

Working Principle
The working principle of TG.22.0222 is based on the characteristics of an antenna, particularly how the current is distributed within the antenna structure when it is subjected to an electromagnetic (EM) wave.

When an EM wave is incident on an antenna, the electric and magnetic field components in the EM wave cause currents, known as antenna currents, to be induced in the antenna. These currents are distributed along the antenna, depending on the type of antenna used. The antenna then radiates the current away from its structure. This is referred to as the antenna gain or directivity. The amount of gain or directivity is determined by the design of the antenna and the currents that it supports.

For TG.22.0222, the antenna is designed to provide high directivity across a wide range of frequencies. This is accomplished through the use of a complex multi-layer antenna design that utilizes a combination of capacitors, inductors, and resistors to create a directional radiation pattern. By carefully tuning the antenna for specific frequencies, it is possible to achieve a high degree of directivity for a given range of frequencies. This is achieved by controlling the impedance of the antenna, which is determined by the capacitance and inductance of the antenna elements as well as the length of the antenna, in addition to other factors.

Conclusion
TG.22.0222 is a versatile RF antenna designed for use in indoor wireless applications, such as for cellular access points, wireless LANs, and Bluetooth systems. Its wide frequency range makes it suitable for a range of applications, and its low profile design allows it to be easily installed in confined spaces. The antenna\'s complex multi-layer design provides high directivity across the entire frequency range, and its robust construction allows it to withstand environmental conditions and vibrations. Overall, TG.22.0222 is an excellent choice for indoor wireless applications, due to its wide range of features and performance capabilities.
