As a consequence, the radiation pattern and input impedance of each array element are disturbed by the presence of the other elements. This effect is known as antenna or mutual coupling and can be evaluated through the use of a coupling matrix, as shown in Appendix C, for antennas that are...
The proposed approach is demonstrated on a four-element array for 5G MIMO applications. Each radiating element in the array is constituted from a 3 × 3 matrix of interconnected resonant elements. The technique involves (1) incorporating matching stubs within the resonant elements, (2) ...

This invention relates to an antenna array system. A problem with antenna array systems is that they provide rather inefficient use of hardware and have inflexible resource allocation. The invention p
(TR) modules which operate over a broad frequency range. The TR modules are used to transmit and receive radar signals in a phase array type radar system, such as a matrix antenna array. To control each TR module in the array, a combination of oscillator and information control signals is...
