By increasing the number of signals generated within the feed network, which are utilized to generate the third RF signals for supplying to the antenna, the range of possible tilt angles is increased as are the possible range of beam patterns in order to satisfy the coverage and capacity requirements.

摘要： Embodiments of the present invention relate to the field of communications technologies, and provide a base station antenna and a base station antenna feed network. The base station antenna includes a transceiver array, a first-level vector synthesis network, a second-level phase shifter array, a second-level vector synthesis network, and an antenna unit array. By using the second-level vector synthesis network, the base station antenna makes phase differences between multiple vector signals sent to antenna units smoother, thereby extending an adjustable range of a downtilt on the premise that the number of transceivers is as small as possible.

摘要： A radar detector is used with a radio link, the radio link characterized by high duty factor operation of a radio transmitter. The radar detector is located a sufficient distance from the radio transmitter that the radar detector is not overwhelmed by the radio transmission signal in that channel and can detect sufficiently low level radar signals to ascertain potential radio interference at the radar from said radio transmitter. The results of the radar detection are communicated to the transmitter in a way that impacts the transmitter's use of the sensed channel. This communication can occur reactively when a radar detection is achieved (the absence of which indicates no radar has been detected) and/or can be a periodic or event-driven indication that the channel is available for operation (the information expiring if the result is not refreshed).
