Introduction to LC Antenna
Phase shifter is the core component of phased array antenna. The microwave phase is adjusted by a phase shifter to control the signal receiving and transmitting direction, and a phase shifter controls a radiation unit.Existing phase shifters generally use semiconductor diodes, the price of about 10,000 to 50,000 yuan, liquid crystal phase shifters cost about 1/10.
Principle of liquid crystal phase shifter: the change of liquid crystal dielectric has different effects on the microwave-induced electric field, which leads to the change of microwave phase. |
