Nowadays, navigation antennas are more and more widely used in our daily life, such as mobile phones, electronic watches, cars, navigation equipment, etc. in order to apply different purposes, navigation antennas are also divided into many kinds, such as built-in antenna, GPS antenna, external antenna, time service antenna, etc; So what's the difference between PCB antenna and GPS ceramic antenna?
Difference 1: GPS ceramic antenna and PCB antenna have different definitions
GPS ceramic antenna uses 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 in the satellite signal, so as to further calculate the navigation information such as the position, rate and time (PVT) of the receiver carrier. It can be divided into block ceramic antenna and multilayer ceramic antenna.
PCB antenna refers to the Department on the PCB for wireless reception and transmission. It is usually set on Bluetooth or wireless transmission module. Its wiring generally needs a clearance area to prevent the signal from scattering and affecting the reception effect; Make the omnidirectional antenna directional.
Difference 2: the characteristics of GPS ceramic antenna and PCB antenna are different
In terms of dielectric constant, GPS ceramic antenna is higher than PCB antenna, so the use of ceramic antenna can effectively reduce the size of antenna. When designing PCB antenna, the surrounding area should be clear. Metal tools are not allowed. The original with metal should be reliably grounded. Special attention should be paid not to apply copper.
GPS consists of three parts: space segment, control segment and user segment. The space segment consists of 24 satellites spread over six orbital planes. The satellite has an orbital height of 20200km, an inclination of 55 degrees and a period of 12 hours. The orbit spread of the satellite ensures that at least 6 satellites can be seen at any time around the world, and the satellite continuously provides users with location and time information.
The control section is composed of one main control station, five monitoring stations and three injection stations. The main control station is located in Colorado. The monitoring station tracks all GPS satellites in the field of vision, collects satellite ranging information, and sends the collected information to the main station. The master station calculates the satellite's fine orbit and generates the navigation information of each satellite, which is transmitted to the satellite through the injection station.
The user segment consists of a receiver, a processor and an antenna. The position, speed and time of the user are calculated by receiving the satellite broadcast signal. The idea of GPS is based on satellite ranging. Users calculate their position by measuring the distance between them and the satellite. When the position of the satellite is known, each GPS satellite sends position and time signals, and the user receiver measures the time delay of the signal reaching the receiver, which is equivalent to measuring the interval between the user and the satellite. Measuring four satellites at the same time can solve the position, speed and time.
The above is the difference between GPS ceramic antenna and PCB antenna. Suzhou Gongwei Electronic Technology Co., Ltd. has 15 years of experience in antenna cable research and development. You are welcome at any time.
