Applications of spring coil 433Mhz antenna design
What is 433MHz Antenna Design?
Through testing, the 433 MHz miniaturized spiral printed antenna designed by C&T RF Antennas Inc performs well.
The antenna design incorporates the structural characteristics of the traditional external helical antenna and the monopole snake-shaped printed antenna. The microstrip line is used to imitate the wiring form of the helical antenna on the dielectric substrate, which reduces the structural size of the antenna.
In addition, the loading of passive lumped elements ensures the miniaturization of the antenna, so that the antenna does not need to extend the physical length to reduce the resonance frequency. The final simulation test results show that the performance of the antenna meets the expected indicators.
Welcome to C&T RF Antennas Inc. to design your 433 MHz antenna.
Wireless transmission distance estimation calculation
The best antenna length is 1/4 of the wavelength
Wavelength = wave speed/frequency
Wave speed = speed of light = 3*100000000
The alternating current in a piece of metal wire can emit alternating induced electric fields and induced magnetic fields into space, which is the emission of radio signals.
On the contrary, the alternating electromagnetic field in space can induce an alternating current when it encounters a metal wire, which corresponds to the reception of wireless signals.
When the radio is transmitting and receiving, it is hoped that the alternating current in the wire can be effectively converted into an electromagnetic wave in space, or the electromagnetic wave in space can be most effectively converted into an alternating current in the wire.
This requires the wire used for transmitting and receiving to obtain the best conversion efficiency, and the wire used for transmitting and receiving wireless electromagnetic wave signals that meet such requirements is called an antenna.
Theory and practice have proved that when the length of the antenna is 1/4 of the wavelength of the radio signal, the transmission and reception conversion efficiency of the antenna is the highest.
Therefore, the length of the antenna will be determined according to the frequency or wavelength of the transmitted and received signals.
As long as you know the center frequency of the corresponding transmission and reception, you can use the following formula to calculate the wavelength of the corresponding radio signal, and then divide the calculated wavelength by 4 to get the corresponding optimal antenna length.
