| Antenna (or aerial) represents a convertor for getting or transferring electromagnetic waves. GSM antennas (GSM stands for Global System for Mobile Communication) are produced in two types: directional and omnidirectional antennas, and are designed to be used in places where the connection to the mobile operator can't be established. The use of high gain GSM antennas permits to increase the communication quality and speed up data interchange in GPRS and EDGE modes. In addition to better connection and the chance to apply the mobile communication out of the covering, cell antennas are known to decrease the backward radiation towards the user's head. It is significant, since the rate of electromagnetic wave power absorption is minimized and the antenna's effectiveness is enhanced. This way, the use of GSM antennas provides high level of performance and health protection. The purpose of cell phone antennas is to convert electrical power between a circuit and the air, that is the reason why the efficiency of the gadget depends on its input and radiation characteristics. Selecting an antenna is a significant move, so we recommend to consult the professionals. Specialists in the firm where you're planning to acquire the antenna will help you to make the right choice. But still, do not forget a number of important factors while choosing a cellular antenna: - Power should be supplied to the antenna without being reflected back to the circuit. It means that the feeding point supplies the electric power, but doesn't take it back; - The power transmitted to the antenna is transformed into radio waves; - If there are any troubles with the impedance, power should not be supplied to the antenna; - Remember that in case the antenna is made of high-loss materials, such as dielectrics and conductors, the supplied power will be lost due to transformation into the heat. So, high gain cell antennas are a perfect choice in case you need a stable connection and high speed of data transfer. What is more, the usage of cell antennas reduces the level of electromagnetic wave power absorption and in such a way tells favorably on your health. |
