Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
CEA-909 is the ANSI standard for 8VSB/ATSC smart antennas.The basic concept is that the smart antenna either physically rotates toward the signal, or is stationary, but has elements pointed in different directions and uses only those elements that maximize the received signal.
ADA (an abbreviation of adaptive antenna) is an advanced smart antenna, using multichannel controlled reception pattern antenna (CRPA), [1] designed for various platforms, including UAVs, planes and ships, manufactured by the MLM factory of the Israeli Aerospace Industries (IAI). [2] [3]
Digital antenna array (receiver segment) Digital antenna array (transmitter part) Digital antenna array (DAA) is a smart antenna with multi channels digital beamforming, usually by using fast Fourier transform (FFT). The development and practical realization of digital antenna arrays theory started in 1962 under the guidance of Vladimir Varyukhin .

Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. The following is a list of devices that support the technology from various UWB silicon providers.
