Problems solved by technology
The main mode of the common rectangular waveguide waveguide power divider is TE10 mode, which has the advantages of small insertion loss and large power capacity, but there is a cut-off mode, so the transmission bandwidth is limited, and it cannot be used as a broadband or multi-frequency power divider
[0009] In summary, the existing CTS panel antenna array is designed in a single-frequency band due to the limitation of the feed network, and can only design the receiving and transmitting antennas separately, which cannot realize the miniaturization of the antenna system
Moreover, the existing antenna adopts the excitation method of equal amplitude output, which leads to high sidelobe of the antenna in the front direction, which is easy to cause interference from adjacent satellites in the antenna transmission, and the anti-interference performance of the antenna is poor, so it cannot be effectively applied in the actual environment.

Description
technical field [0001] The invention relates to the technical field of antenna communication, in particular to a parallel plate waveguide power divider, a CTS antenna, and an antenna device. Background technique [0002] There is a growing need for wireless broadband channels that transmit data at very high data rates, especially in the field of mobile satellite communications. However, especially in the field of aviation, there is a lack of suitable antennas that can meet the conditions required for mobile use, in particular, such as integrated transceivers and low-profile antennas. For directional wireless data communication with satellites (for example, in the Ku or Ka frequency bands), there are also extremely high requirements on the sidelobe performance of the antenna, since interference between adjacent satellites must be reliably placed. [0003] All regulations are intended to ensure that no interference occurs between adjacent satellites during directional transmi...
