BB2503S type antennas are a kind of RF antennas used widely in the current wireless communication industry. In fact, this kind of antennas can be applied in many aspects , such as sending and receiving cellular signal or bluetooth signal, for example .

In terms of application fields, BB2503S is an all-round antenna which can be applied to almost all modern communication systems, like GSM, CDMA, GPRS , WCDMA, UMTS , LTE , CDMA , WIFI , WiMAX , 4G , 5G and so on . With wide band characteristic , the BB2503S antennas is featured with high gain, stable wave performance and low return loss, which allows the antenna performance reach the maximum extent.

The BB2503S antennas also feature unique design which makes it work much more effectively. The design applies the folded metal, which helps it to gain huge increase in effective directivity and radiation efficiency. It uses the new interference wave design and combining the dielectric resonance it effectively guarantee the antenna gain and realize the ultra wide frequency bandwidth. The standard design allows IP67 waterproof so they are able to work in all weather.

In terms of working ways, the main working principle of the BB2503S antennas is that high-efficiency magnetically polarized radiator is placed near to the metal radiating element , and then its generated magnetic field is inducted to the nearby metal radiating element , thus a strong magnetic swirling flow is formed around the radiating element. The strong and stable swirling flow forms a capacitive loop which is the key factor to form a harmonic current circulation. Then due to the harmonic current circulation, electricity turns into the electromagnetic wave which will be radiated from the antennas.

Therefore, the BB2503S type antennas make use of the radiation effect of the folded metal to convert high frequency current flowing in the antenna into the electromagnetic wave . This is the working principle of the BB2503S antennas. With the advantage of high gain, low return loss, wide frequency bandwidth, and excellent waterproof capability, the BB2503S antennas is suitable for a wide range of applications. Such as the cellular signal receiving, GPS navigation, radio broadcasting, WIFI transmission and high quality video signal receiving.
