An approach suitable for millimeter-wave dielectric resonator antenna (DRA) arrays is presented. The methodology involves fabricating precise cavities in acrylic templates and filling them with composite dielectric materials to create a monolithic polymer-based DRA (PRA) array layer. The excitation feed lines are fabricated on a separate substrate layer and the two layers are aligned and bonded together...
Phased array technology has brought revolution not only in the defense but also in the commercial industry. Considering the development taking place in this area, it can be safely said that the future belongs to the phased array technology. This paper presents system level modeling and integration of the front end of phased array radar. This includes the modeling and simulation of an antenna array,...
Phased array radars have received considerable importance both in commercial and defense communications. Lot of research has been carried out regarding development of its necessary components such as the antenna array, transmit/receive module (TRM) and processor unit. The cost, efficiency, wide bandwidth, and fabrication technology for the TRM have been pursued as key research areas. Cost reduction...
This paper demonstrates the signal combining by use of adaptive algorithms for wireless communication networks. The adaptive combiner operates under different noise variances on each branch of the multi-antenna receiver. We utilise adaptive signal combining technique with least mean squares (LMS) algorithm based on Newton's Recursion Method. It is shown that the adaptive combining filter with LMS...
