Planar antenna is a type of antenna widely used in communication systems. It has a simple structure and is easy to make. It can be arranged on a flat medium, such as a metal plate, a printed circuit board, etc. Planar antennas are primarily made of metal and usually come in the form of sheets, lines, or patches.
The structure of planar antennas can be divided into the following common types:
Microstrip Antenna: It consists of a metal patch and a ground plane. Patches can come in different shapes, such as rectangular, round, oval, etc. Microstrip antennas are small, lightweight, and have simple manufacturing processes. They are often used in mobile communications, wireless local area networks (WiFi), satellite communications and other applications.
Patch Antenna: It is similar to a microstrip antenna and consists of a metal patch and a ground plane. The patch usually adopts a square or circular shape, has a wider frequency band and higher gain, and is widely used in wireless communication systems, radar, avionics and other fields.
Dipole Antenna: Also called a dipole antenna, it consists of two wires of equal length. One end of the wire is connected to the signal source and the other end is open. A half-wave antenna is an omnidirectional antenna suitable for radio transmission and reception.
Helical Antenna: It consists of a spiral coil, usually in a disk-shaped structure. Disk antennas can achieve longer wavelengths and larger gains, so they are widely used in aerospace, satellite communications and other fields.
Planar antennas are widely used in communication systems, mainly including the following aspects: Mobile communication systems: Planar antennas are used in mobile devices such as mobile phones and tablet computers to receive and transmit wireless signals.
Wireless LAN (WiFi): Planar antennas can be used to receive and send wireless network signals to achieve wireless interconnection.
Satellite Communications: Flat antennas are used in satellite communications systems to receive and transmit signals.
Radar System: Planar antennas play an important role in radar systems for detecting and tracking targets.
Aerospace field: Planar antennas are widely used in aerospace equipment such as aircraft and satellites for communication and navigation.
All in all, planar antennas have the advantages of simple structure, easy manufacturing, and convenient layout. They are widely used in mobile communications, wireless networks, satellite communications and other fields, and play an important role in the development of modern communication technology.
