How to make a 433MHz Antenna Design?

433Mhz vs 315MHz
The difference between the 433M wireless module and the 315MHz wireless module is the carrier frequency (the carrier frequency of the 433MHz wireless module is 433MHZ, and the carrier frequency of the 315MHz wireless module is 315MHZ).
The 433MHz has a shorter wavelength, shorter antenna, and stronger directivity. 433MHz has less winding performance, but 433MHz has a strong penetrating ability.
The wavelength of 315M is longer than that of 433MHz, and the antenna is longer than that of 433MHz. The directivity is not as strong as that of 433MHz. 315MHz has better-winding performance, but 315MHz has a weaker penetrating ability. Everything else is the same.
2. 433MHz coil antenna design
C&T RF Antennas Inc. company (433mhz antenna supplier) provides all kinds of antenna spring specifications and production antennas.
Because the full physical size antenna is too long, only make it into a spring shape to reduce the size, so that the walkie-talkie is convenient for portable use.
The design and development production line can transmit and receive polarized electromagnetic signals rotating in space.
Such antennas are usually used in ground stations for satellite communications.
Use an unbalanced feeder, such as a coaxial cable, to connect the antenna. The center of the cable is connected to the spiral part of the antenna, and the outer sheath of the cable is connected to the reflector.
We May Need to use amateur radio frequency bands, may need to use higher frequencies (such as 315MHz, and 433MHz) to reduce antenna size.
Attenuator:
It is designed to prevent the signal from being too strong affecting the direction-finding, and attenuating the antenna signal. Walkie-talkie:
It may not be related to direction-finding.
It should be a dedicated receiver. An overly complex walkie-talkie may not receive the signal.
Yagi antenna: channel antenna, fishbone antenna, composed of a director, dipole antenna, and reflector
RF433mhz wireless module
1. What is a 433mhz wireless module
The 433MHz wireless transceiver module uses high-frequency radio frequency technology, so it is also called the RF 433mhz radiofrequency small module. It is composed of a single-IC RF front-end produced by all-digital technology and ATMEL’s AVR single-chip microcomputer.
It can transmit data signals at a high speed, and it can package, detect, and correct wireless data.
The components are all industrial-grade standards, stable and reliable, small in size, and easy to install. It is suitable for a wide range of fields such as security alarms, wireless automatic meter reading, home, and industrial automation, remote control, wireless data transmission, etc.
2. Antenna selection of 433mhz wireless module
The 433mhz wireless module is low-consumption and powerful. It is widely used in robot control, smart homes, wireless meter reading, and other fields. The product is an industrial-grade design and is suitable for poor outdoor environments.
When the module finds that the distance is not enough during use, it is often recommended to select a suitable antenna to increase the communication distance. So which antenna is good for 433mhz wireless modules?
The antenna is an important part of the communication system. Its performance directly affects the indicators of the communication system.
When choosing an antenna, you must pay attention to its performance. In addition, the antenna gain is one of the important indicators of the antenna, which is the directivity and efficiency. The product is the performance of the size of the antenna radiated or received.
3. Which antenna is used for the 433mhz wireless module
Generally, commonly used wireless modules require an antenna impedance of 50 ohms. 433 wireless modules can use general 433MHz spring antennas, elbow/straight rod antennas, sucker antennas, etc.
These antennas are dedicated antennas designed for 433MHz wireless communication systems. The standing wave ratio has good performance, ingenious structure, convenient installation, stable performance, and good anti-vibration and aging ability. Users can choose antennas according to their own application environment.
4. The influence of the transmission distance of the 433mhz wireless module
After purchasing the 433m wireless transmitter module sold by the manufacturer, the customer finds that the transmission distance is shorter than the distance described in the product, which may result in failure to operate normally.
The following introduces which factors affect the transmission distance of the wireless transmitter module and how to increase the transmission distance.
4.1. The transmission distance introduced by the manufacturer’s product is more accurate data that was tried in an open area with a better environment. Customers bought it and used it with more environmental interference, such as building walls, trees, etc.
Ways to increase the transmission distance: When the transmission distance is not long enough, you can choose some places with fewer obstacles to increase the distance.
4.2. After the power supply is used for a period of time, the voltage will decrease, resulting in a decrease in the transmission distance. If you want to increase the transmission distance, you can replace a power supply with large capacitance and a stable voltage.
4.3. In order to reduce the transmission time, some people increase the rate of the 433 wireless modules, resulting in a reduction in the transmission distance. Therefore, the transmission rate can be lowered when in use, which can increase the transmission distance of the wireless module.
4.4. The antenna is one of the factors that affect the transmission distance of the module. The high-gain antenna can make the distance transmission farther. In addition, increase the installation height of the antenna, and try to keep the antenna above 2 meters from the ground, so as to achieve a better transmission distance.
C&T RF Antennas Inc. supplies the spring antenna coil helical antenna with 315 Mhz, 433 Mhz, 868 Mhz, 915 Mhz, Wifi, GSM, etc.
