What's the center frequency of antenna

Each antenna has a certain frequency range called bandwidth. In the range, the antenna has the lower impedance and the highest efficiency, which is equivalent to a band-pass filter. The best frequency point in the middle of the frequency range is the center frequency, its SWR is the lowest, and the efficiency is higher.  ...

Importance of antenna impedance matching

Impedance is an important parameter of the antenna, which is determined by the physical structure of the antenna, such as the shape, size, material, and environment of use. The impedance matching of the antenna is the process of matching both the impedance of the antenna and transmitting the source through tuning. So, why do you need to do antenna impedance matching?  ...

What's the Spring antenna

The spring antenna is also called the helical inductive antenna, which is a kind of helical antenna. It can radiate and receive radio waves. when transmitting, it can convert high-frequency current into electromagnetic waves; when receiving, it can convert electromagnetic waves into the high-frequency current. So it plays a very important role in radio communication.  ...
