A flat panel antenna is a common type of radio receiving and transmitting
antenna, which is named for its flat appearance. Its internal structure is
complex, consisting of one or more metal sheets, capacitors, and inductors. The
combination of these components can effectively change the characteristics of
the antenna, enabling it to have excellent receiving and transmitting
performance.
Metal Sheets
Metal sheets are the main components of flat panel antennas. They are made
of a single piece of metal, and their shapes can be square, rectangular, or
other special forms. The size and shape of the metal sheets affect the receiving
and transmitting capabilities of the antenna. By adjusting their size and shape,
the characteristics of the antenna can be effectively modified, thereby
improving its receiving and transmitting performance.
Capacitors
A capacitor is an electronic component that can store electrical energy and
convert it into a specific voltage. In flat panel antennas, the main function of
capacitors is to adjust the frequency of the antenna, allowing it to receive and
transmit radio waves of specific frequencies. There are many types of
capacitors, such as capacitor sheets, capacitor tubes, and fixed capacitors.
Inductors
An inductor is an electronic component that can convert electrical energy
into magnetic energy. In flat panel antennas, inductors mainly serve to adjust
the antenna's frequency, enabling it to receive and transmit radio waves of
specific frequencies. There are various types of inductors, including coils,
magnetic rings, and resonant inductors.
The rational combination of these internal components ensures that flat
panel antennas can perform well in different communication scenarios, providing
stable and efficient signal transmission and reception.
