Beamforming or transmit beamforming (TxBF) technology produces the strong directional radiation pattern based on the strong correlation of the spatial channel and wave interference principle, making the main lobe of the radiation pattern adaptively point to the wave direction. This techn...
Beamforming is especially beneficial for radar as it can reduce signal radiation in some directions while boosting the signal radiation in the desired direction. As a result, the accuracy of the radar reflection signal is substantially improved. The large number of antennas in the system also add...

Aperture antennas are microwave transceivers fashioned into disks, dishes, and rectangular arrays, as seen on cell phone towers. The antenna radiation pattern appears as a torus or horn around the beam axis. Others can include helical, conical, parabolic and more; dozens of other antenna types an...
Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz). With the use of antennas and transmitters, an RF field can be used for...
radiation therapy can be used to manage the size of the cancer to reduce pain and other symptoms associated with the growth. Palliative care may be used when a patient wishes to decline aggressive treatment, or when a patient recognizes that the cancer is incurable, making aggressive treatment ...
