433MHz Lora Antenna Module Antenna Design And Choose
The 433MHz built-in antenna has a relatively low frequency and requires a long wavelength to meet the antenna design needs. Therefore, onboard antennas and other forms require a large area to be realized.
It is often difficult to reserve such a large area for the onboard antenna in the product.
The Ipex connector external antenna is not only expensive but also difficult to assemble, so the spring antenna has become everyone’s choice of 433M The first choice for built-in antennas, spring antennas are widely used in Lora products.
Can the built-in 433MHz spring antenna be chosen at will? Can I buy a built-in 433MHz spring antenna from the market?
In fact, this is not the case. Many friends find that the built-in 433MHz spring antenna they buy often does not work well. The communication performance distance is very poor, and the distance reached by the module manufacturer is much different. Why is this so?
The above problems are caused by two reasons. One is because the manufacturer of the purchased 433MHz spring antenna does not have antenna technology capabilities.
Another reason is due to the characteristics of the antenna itself. These two reasons together led to the poor performance of the 433MHz spring antenna on the customer’s product.
Let’s analyze them one by one.
1. The manufacturer of the built-in 433MHz spring antenna does not have antenna technical capabilities:
Many manufacturers do not have antenna technology capabilities themselves. They bought other people’s 433Mhz spring antennae from the market, and then directly produced and sold them in accordance with the size and shape of others.
But the antenna is an extremely sensitive electronic part. A slight difference in size will cause serious performance degradation. Manufacturers do not use special antenna test equipment to confirm antenna performance indicators to produce by measuring the size. Naturally, it is easy to cause the product to fail.
When the customer bought such a 433MHz spring antenna, the performance could not be guaranteed. Even the product performance of different batches is often inconsistent.
So when you buy a 433MHz spring antenna, you must find a company with antenna technology capabilities to buy it. Otherwise, the performance of your Lora antenna is not guaranteed.
2. The characteristics of the built-in antenna:
As mentioned in the previous article, the characteristics of the antenna itself cause the antenna to exhibit different operating frequencies and impedances in different products.
As a result, even if you buy a regular built-in 433MHz spring antenna, the performance is still not guaranteed.
How to solve it? In fact, the solution is to require the antenna company’s engineers to do the impedance-matching debugging of the antenna for the actual product of the customer.
Only in this way can it be ensured that the built-in 433MHz spring antenna can match the customer’s products. The specific debugging method requires customers to add impedance-matching devices between the antenna and the RF circuit on their products.
Engineers test and debug these devices with special equipment for customers’ products so that the Lora antenna matches the product.
From the above content, it can be seen that when choosing a built-in 433MHz spring antenna, it is not so much to choose an antenna but to choose an antenna company.
Because only a company with technical strength can make your product truly adapt to the 433MHz spring coil antenna.
C&T RF Antennas Inc has lots of well-designed 433MHz spring coil antennae for your best choice.
