Antenna is a transducer for getting or transmitting electromagnetic waves. GSM antennas are created in 2 types: directional and omnidirectional ones, and are designated to be applied in spots where the connection to the mobile operator can't be established. The usage of high gain GSM antennas allows to improve the communication quality and the speed of data transmission in GPRS and EDGE modes. In addition to improved connection and the opportunity to use the mobile communication beyond the covering, cellular antennas are famous to reduce the radiation towards the user's head. It's essential, since the level of electromagnetic wave power absorption is decreased to the minimum and the effectiveness of the antenna is increased. In such a way, the application of cell antennas ensures high level of effectiveness and health protection. The function of GSM antennas is to convert electrical power between a circuit and the air, this is why the effectiveness of the gadget depends on its radiation and input characteristics. Choosing an antenna is an essential step, so we would advise to talk to the professionals. Specialists in the company you are buying the antenna from will assist in making the right choice. But still, do not forget some significant factors while selecting a GSM antenna: - Power is supplied to the antenna with no being reflected back to the circuit. It signifies that the feeding point should supply the electric power, but not take it back; - The electric power transferred to the antenna is transformed into radio waves; - In case of some problems with the impedance, the power shouldn't be supplied to the antenna; - Note that if the antenna is made of high-loss materials, such as conductors and dielectrics, the supplied electric power will be transformed into the heat and lost. As far as you understand, high gain cellular antennas represent a wonderful choice in case you need a stable communication and high-speed data interchange. What is more, the use of cell phone antennas reduces the specific absorption rates and in this way tells positively upon your health. |
