Abstract:There are two common wireless transmission antennas: indoor antennas and outdoor antennas. There are many types of outdoor antennas, such as a pot-shaped directional antenna and a rod-shaped omnidirectional antenna; a wireless antenna converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or The reverse transformation, the components used to transmit or receive electromagnetic waves in radio equipment, are widely used in engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy.

 

There are many types of antennas on the market, and each antenna has its own characteristics. Let us look at the difference between GPS ceramic antennas and wireless antennas. In recent years, ceramic technology has developed rapidly. The low-temperature co-fired ceramic technology has become a new generation of microwave device processing because of its high assembly density, good frequency characteristics and high batch processing consistency. Therefore, ceramic antennas have become a new generation. The navigation antenna, then what is the difference between the ceramic antenna as a new product and our common wireless transmission antenna? Let me tell you:

Ceramic antenna

The ceramic antenna is a kind of navigation antenna. It is made of ceramic material and then reduced by the high dielectric constant of the ceramic. The two sides are made of metal as the electrode and polarized by DC high voltage. It has a piezoelectric effect and can be divided into a block ceramic antenna and a multilayer ceramic antenna.

Its working principle is to use GPS satellite to achieve navigation and positioning, and the user's receiver is mainly to extract the pseudo-random noise code and data code in the satellite signal to further solve the position, speed and time of the receiver carrier ( PVT) and other navigation information. It has been widely used in electronic industries such as watches, handheld devices, and automobiles.

Wireless antenna

There are two common wireless transmission antennas: indoor antennas and outdoor antennas. There are many types of outdoor antennas, such as a pot-shaped directional antenna and a rod-shaped omnidirectional antenna; a wireless antenna converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or The reverse transformation, the components used to transmit or receive electromagnetic waves in radio equipment, are widely used in engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy.

After reading the above, you should be clear about the difference between GPS ceramic antennas and wireless antennas.
