Be converted to the electromagnetic wave of free space radiation；During reception, the electromagnetic wave of day bundle of lines free space is converted to and can passed in transmission line
Defeated guided wave or high frequency electric is transported to receiver.Directional transmissions and receiving then refer to antenna can by specified direction radiation or
Receive electromagnetic wave energy.How is the performance of antenna, directly affects the use of wireless device.Ordinary radar system, microwave are led to
For news system etc., it is desirable to which the intensity of emittance is not very high, and particular/special requirement is not also done to wave beam, then generally selects one
Slave antenna is with regard to that can complete task, such as parabola antenna.
Asking for such as space structure, antenna performance quality will can be run into height another compound module of two band antennas
