The invention provides a half-duplex multi-band antenna control system and a half-duplex multi-band antenna control method for an Internet of Things terminal. The control system comprises a pluralityof antennas, each antenna is connected with a half-duplex bidirectional radio frequency amplification module; wherein the antenna is used for receiving a radio frequency signal of a preset frequency band and transmitting the radio frequency signal to the corresponding half-duplex bidirectional radio frequency amplification module, each half-duplex bidirectional radio frequency amplification moduleis connected with one single-pole multi-throw switch, the single-pole multi-throw switches are connected with the digital voltage-adjustable control attenuator, and the digital voltage-adjustable control attenuator is connected with the broadband amplification module; and the control logic of the half-duplex bidirectional radio frequency amplification module is consistent with that of the single-pole multi-throw switch.
Description
technical field [0001] The disclosure belongs to the field of half-duplex multi-band antenna control, and in particular relates to a half-duplex multi-band antenna control system and method for IoT terminals. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The antenna is an essential device in wireless devices. The essence of the antenna is an energy conversion device that converts electrical signals into electromagnetic waves or vice versa. The physical network antenna is particularly used in a unique application scenario. The inventors found that the current ultra-wideband antenna covering the frequency band of the Internet of Things has the problems of uneven gain, large size and high price. Contents of the invention [0004] In order to solve the above problems, the present disclosure provides a half-duplex multi-band antenna contr...
