Design of a Broadband Frequency Offset Van Atta Array

Abstract

Abstract-A novel broadband Van Atta array operating in a broadband with frequency offset characteristic is proposed. A single sideband mixer is introduced to achieve sideband choice without utilizing filters which make this array have excellent performance and wider applications than the conventional Van Atta array. The simulated results of the amplitude and phase of the array show that this antenna array can achieve retrodirectivity with frequency offset and good isolation in a broadband. The experimental performance of the array is observed within the frequency range from 2.8 GHz to 3.4 GHz.

Synthesis ofn-way active topology for wide-band RF/microwave applications

“…In this optic, different extensions of the popular Wilkinson power-splitter were proposed in *Email: blaise.ravelo@yahoo.fr ISSN 0020-7217 print/ISSN 1362-3060 online ß 2012 Taylor & Francis http://dx.doi.org/10.1080/00207217.2011.643488 http://www.tandfonline.com the literature. But mostly, with classical passive devices which are regularly used in RF/microwave systems, the insertion loss unavoidably increases with the way number of the power combiners (Simons and Ponchak 1990;Eccleston 2006;Chen and Zhang 2007;Joardar, Jaint, Bandewar, and Bhattacharya 2008;Hubbard and Ordy 2009;Chen, Wang, Shi, Zhang, and Tong 2010;Wu, Liu, Li, Yu, and Liu 2010;16 Way). In this scope, we have the same effects for the another family of n-way devices generally used for the transformation of balanced to unbalanced signals which are frequently found for the microwave applications and also for the near-field measurement test bench (Baudry, Louis, and Mazari 2006).…”

Simplified design, simulation, and lab‐environment measurement scheme for retro‐directive antenna arrays

“…The response is transmitted without any prior knowledge about the location of source and is completely automatic without the use of expensive phase shifters and complex digital circuits autonomous beam steering capability of these arrays makes them a technology of choice for mobile, satellite and back scatter RF communication. It is also used in RF tracking and pointing systems, transponders, UAV command and control systems, microwave beacon and solar power satellites . Two basic designs of retro‐directive antenna array are Van Atta array and Phase Conjugating array.…”
