In recent years, with the rapid development and application of ceramic technology, low temperature co-fired ceramic technology has rapidly become an important means of processing new generation microwave devices because of its high assembly density, good frequency characteristics and high consistency in batch processing. therefore, the ceramic antenna has become a new generation of navigation antenna, so what is the difference between the ceramic antenna as a new product and our common wireless transmission antenna? 

The following editor tells you: 

Ceramic antenna. 

Ceramic antenna is a kind of navigation antenna, which is made of ceramic material, and then uses the high permittivity of ceramic to reduce the volume of the antenna. Both sides of the antenna are polarized by metal as electrodes. 

It has piezoelectric effect and can be divided into block ceramic antenna and multilayer ceramic antenna. 

Its working principle is to use GPS satellite to realize navigation and positioning, and the main task of the user's receiver is to extract the pseudo-random noise code and data code from the satellite signal, so as to further calculate the navigation information such as position, speed and time (PVT) of the receiver carrier. 

At present, it has been widely used in watches, handheld terminal devices, automobiles and other electronic industries. 

. 

Wireless antenna. 

There are two kinds of common wireless transmission antennas: indoor antenna and outdoor antenna. 

There are many types of outdoor antennas, such as pot-shaped directional antennas and rod-shaped omnidirectional antennas. 

A wireless antenna is a component that transforms the guided waves propagated on the transmission line into electromagnetic waves propagated in unbounded media (usually free space), or conversely, and is used to transmit or receive electromagnetic waves in radio equipment. It is widely used in radio communications, radio, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems. 

After reading the above, do you know the difference between ceramic antenna and wireless antenna? 

With the rapid development of science and technology, navigation antennas are more and more widely used in our lives, and there are more and more varieties, such as Beidou antenna, GPS antenna, GPS internal antenna and so on.
