Practical Phased-Array Antenna Systems is based on a set of lecture notes that were prepared for Practical Phased-Array Systems, an intensive course given in 1975. This text is an introduction to the fundamentals of phased-Array antenna systems without extensive mathematical equations or...
To decide among several designs of large phased arrays, each must be designed in detail and realistic cost estimates obtained. Part of the design of a large array should include a small pilot antenna to test as many aspects of the proposed large one as possible. A large array should never ...

A system for distributed phased array multiple input multiple output (DPA-MIMO) communications is disclosed. The system includes beamforming (BF) modules. Each BF module comprises a beamforming antenna, a downconverter that downconverts a beamformed antenna radio frequency signal to an intermediate ...
Phased array antenna was first proposed in the early nineteenth century and its complete theoretical framework had been established since then. As an important component in radar systems, the phased array antenna controls beam emission and steering through phase modulation. Microwaves and optical waves ...
When a uniformly spaced antenna array is adopted, the divergence angle of a single antenna is always larger than the aliasing angle because the width of the antenna is less than of the spacing. For antenna arrays with large and unequal spacing to suppress aliasing peaks [52], the diffraction...
The results of the radiation pattern analysis of the fabricated beamforming antenna are shown in Figure 26. Figure 26. Measured results of the fabricated phased array antenna at each frequency: (a) 3, (b) 4, and (c) 5 GHz. The results in Figure 26 show that the measured beamforming ...
