This paper describes a smart lens antenna array in which a portion of the signal processing is implemented at the analog front end, resulting in reduced processing load. The design of constrained lens arrays is described, and simulations of optimal receiver placement in the array are shown.

Multiple antennas: smart antenna systems
2010Introduction Wireless channels suffer from time-varying impairments such as multipath fading, interference, and noise. Diversity, such as time, frequency, space, polarization, or angle diversity, is typically used to mitigate these impairments. Diversity gain is achieved by receiving independent-fading replicas of the signal.

Smart antennas for wireless communications
2014Future wireless communication systems are expected to support a wide range of services which include video, data and voice. To achieve the necessary capacity for these systems, several smart antenna systems have been proposed and demonstrated at the base station of wireless communication systems.

Smart navigational antenna array
2016 4th International Conference on Methods and Systems of Navigation and Motion Control (MSNMC), 2016The description of smart navigation antenna array with noise suppression and with a sector of space reviewing in the horizontal plane less than 180° (2φ0.5 < 90°) was considered. The detailed block diagram of navigational antenna was built.

CDMA Smart Antenna Performance
2006Applications of smart antenna technology to CDMA networks include both high-mobility cellular/PCS as well as fixed-terminal and low-mobility wireless local hop deployments. Smart antennas are emerging as an integral element of the new wideband CDMA standards for third generation mobile telephone systems across North America, Europe and Asia. This paper

Traditional smart antenna systems are costly, consume great amounts of power and are bulky size. Low-cost Smart Antennas offers a guide to designing smart antenna systems that are low cost, low power, and compact in size and can be applied to satellite communications, radar and mobile communications.

Smart antennas design exploiting time-modulation
2011 IEEE International Symposium on Antennas and Propagation (APSURSI), 2011This paper deals with synthesis of time-modulated linear arrays for adaptive nulling and beamforming where the intrinsic characteristics of this type of antenna arrays can be fully exploited, thanks to the capability of fast reconfiguration of its radiation pattern through the modification of the digital on-off signals controlling the element ...
