433MHz Dipole Antenna Small Antenna

Description

What is a 433MHz Dipole Antenna Small Antenna?

The 433MHz Dipole Antenna Small Antenna CTRF-ANTENNA-FPC-0433-3206-IPEX is an Omni dipole antenna embedded flex PCB antenna with a 433MHz frequency manufactured by C&T RF Antennas Inc.

The 433MHz Dipole Antenna has a 32x6mm small flexible PCB board size, 2dBi common gain, its small size, and flex circuit board very suitable for the curve inside surface of the IoT & M2M devices.

Advantages and disadvantages of 433MHZ frequency

Initially, the frequency range of 430.050 ~ 440.000 MHz was allocated to amateur radio services worldwide. Some radio enthusiasts will use this frequency band for language and data transmission.

But now the 433.050~434.790MHz band has been largely occupied by various industrial, scientific, and medical (ISM-Industrial-Scientific-Medical) applications.

In addition to the backscatter radio frequency identification system, there are also small telephones, telemetry transmitters, wireless headsets, unregistered short-range low-power wireless walkie-talkies, keyless access systems, and many other applications that fill this frequency band. Class cards, etc.

433MHZ is in the UHF (30-1000MHZ) range. The common feature of UHF is that it basically cannot be reflected by the ionosphere.

The propagation methods that play a major role in this frequency band are space wave propagation within line-of-sight, as well as tropospheric scattering and ionospheric scattering. Compared with the high-frequency band, the advantage of this frequency band is that a small-sized antenna can be used for low-capacity systems.

Obviously, this feature is particularly suitable for mobile communications. Tropospheric scattering replaces the radio-relay system on some occasions because it can hop hundreds of kilometers without a relay station, and it can also have a large capacity (multi-channel transmission), which is impossible at low frequencies.

433MHZ is at the low end of UHF. Compared with the high end of 860-960MHZ (usual UHF frequency), because the low end can be reflected by the ionosphere, it is prone to interference.

But at the same time, because it is at the low end of the ultra-high frequency, it also has the characteristics of some high-frequency waves. The communication is simple, easy to implement, and low in cost. It can realize long-distance communication with small power and a much smaller antenna, which is its advantage.

These advantages make it more widely used. Coupled with its UHF communication’s high stability, large capacity, and strong transmission capabilities, its advantages are more prominent.
