Abstract Taper weights that yield low sidelobe beams for phased arrays may be obtained by sampling an appropriate low sidelobe continuous weight function. One- and Two-Dimensional Antenna Arrays A. H. El Zooghby, C. G. Christodoulou, and M. Georgiopoulos Abstract— In this letter, we present a neural network approach to the problem of ﬁnding the weights of one- (1-D) and two-dimensional (2-D) adaptive arrays. In modern cellular satellite mobile communications Quarter-Wave Vertical Antenna Length Calculator. A quarter-wavelength antenna is easy and inexpensive to build and can be an effective antenna with a low angle of radiation (that is, power is radiated out, not up). The formula for calculating the approximate length of a quarter-wave vertical antenna is: - Mechanically-agile directional antennas deployed at the receiving sensors: they are adjusted to the point of highest signal strength. - An antenna array: it is usually made by measuring the TDOA at individual elements of the antenna array. Advantages: - It only needs two measuring units for 2D positioning and 3 for ·D. 1 Beamspace MIMO Architectures for Massive 2D Antenna Arrays Akbar M. Sayeed Wireless Communications and Sensing Laboratory Electrical and Computer Engineering Aug 29, 2013 · Currently, however, there is no 3D codebook for two-dimensional (2D) antenna array MIMO systems with limited feedback. In this paper, based on the existing 2D codebook, we present a limited feedback and transmission scheme for 2D antenna array MIMO systems. ANTENNA SOFTWARE .

The term "phased array" is also used to a lesser extent for unsteered array antennas in which the phase of the feed power and thus the radiation pattern of the antenna array is fixed. For example, AM broadcast radio antennas consisting of multiple mast radiators fed so as to create a specific radiation pattern are also called "phased arrays".
