| An antenna (or aerial) is a convertor for getting or transferring electromagnetic waves. GSM antennas are created in 2 types: omnidirectional and directional ones, and are designed to be applied in the places where there is no connection with the mobile operator.
The use of high gain GSM antennas permits to augment the communication quality and the speed of data interchange through EDGE, or Enhanced Data rates for GSM Evolution, and GPRS, or General Packet Radio Service. In addition to improved performance and the possibility to apply the mobile communication out of the mobile covering, cellular antennas are famous to decrease the backward radiation to the user. It's essential, since the electromagnetic wave power absorption is brought down to the minimum and the antenna's performance is enhanced. In this way, the usage of cell phone antennas ensures excellent performance and high level of health protection.
The designation of cell antennas is to convert power between a circuit and the air, so the performance of the device depends on its input and radiation characteristics. Choosing an antenna is a significant step, so we would recommend to consult the professionals. Specialists in the firm you're acquiring the antenna from will be of great help in making the right choice. But take into account a number of important parameters while choosing a cell phone antenna:
- Electric power is supplied to the antenna with no backward reflection to the circuit. It signifies that the feeding point should supply the electric power, but not take it back;
- The electric power transmitted to the antenna is transformed into radio waves;
- In case of some troubles with the impedance, the power should not be supplied to the antenna;
- Remember that in case the antenna is made of high loss materials, like conductors and dielectrics, the supplied electric power will be lost due to transformation into the heat.
So, high gain cell phone antennas represent a great choice if you need a stable connection and high speed of data transfer. Furthermore, the application of GSM antennas bring down the specific absorption rates and in such a way tells favorably upon your health. |
