Flat panel antenna refer to an antenna that propagates only in one specific direction. Panel antennas are generally used in point-to-point situations, and they are called "patch antennas".
At present, there are several types of flat panel antennas, such as vibrator type and slot type. Their concentrated features are small size, light weight, small wind resistance, and easy installation and use; the built-in tuner integrates the antenna and the tuner, and the adjustment is convenient; the flat panel antenna The efficiency is high, especially suitable for the reception of live satellite TV.
The antenna surface of the dipole-type flat panel antenna is longitudinally cut and consists of five layers of materials.
The first layer and the fifth layer are the antenna protection layer, also known as the radome, which is made of corrosion-resistant medium. It plays the role of preventing oxidation, attenuating the effect of ultraviolet rays on printed circuit boards, and preventing rain and snow erosion.
The second layer is the receiving antenna layer. It is a metal layer of a printed circuit board, on which is printed an antenna array formed by many neatly arranged unit vibrators, so it can be called an antenna substrate layer. This layer determines the technical quality of the flat panel antenna. The shape of the unit oscillator is various.
The third layer is the dielectric layer of the printed circuit board, which supports the second layer.
The fourth layer is the ground conductor layer, which is a layer of metal foil, which not only reflects the antenna array, but also is a part of the feeder to form a microstrip transmission line. The output of the antenna array is connected with the tuner installed behind the flat panel antenna board.
