We are antenna factory ,produce all kinds of antenna .But how can you know all the antenna classification ? Please read below :
1.According to the nature of work, it can be divided into transmitting antenna and receiving antenna.
2. According to the purpose, it can be divided into communication antennas, broadcast antennas, TV antennas, radar antennas, etc.
3. According to the directivity, it can be divided into omnidirectional antenna and directional antenna.
4. According to the working wavelength, it can be divided into ultra long wave antenna, long wave antenna, medium wave antenna, short wave antenna, ultra short wave antenna, microwave antenna, etc. Figure 3 Microwave antenna.
5. According to the structure and working principle, it can be divided into line antenna and surface antenna. The characteristic parameters describing the antenna are the pattern, directivity coefficient, gain, input impedance, radiation efficiency, polarization and bandwidth.
6, 6, according to the number of dimensions can be divided into two types: one-dimensional antenna and two-dimensional antenna. One-dimensional antenna: It is composed of many wires. These wires are either straight lines used on mobile phones, or some smart shapes, like the old bunny ears used on televisions before cables appeared. Monopole and dipole antennas are two very basic one-dimensional antennas. Two-dimensional antenna: Variety, there are sheet shape (a square metal), array shape (a bunch of sheets organized in a two-dimensional pattern), horn shape, and dish shape.
7, 7, Antennas can be divided into three categories according to the use occasions: handheld station antennas, vehicle antennas, and base antennas. Handheld antenna: It is the antenna for personal use of handheld walkie-talkies. There are two common types: rubber antennas and whip antennas. Vehicle antenna: refers to the communication antenna originally designed to be installed on the vehicle. The more common application is the suction cup antenna. There are also antennas in the form of shortened, quarter-wavelength, central inductive, five-eighth-wavelength, and double-half-wavelength antennas on the vehicle-mounted antenna structure. Base station antenna: It plays a very critical role in the entire communication system, especially the communication station as a communication hub. Commonly used base station antennas include glass fiber reinforced plastic high-gain antennas, four-ring array antennas (eight-ring array antennas), and directional antennas.
