Experimental Study of the Retrodirective Antenna Array System in a Multipath Environment
6th Annual Communication Networks and Services Research Conference (cnsr 2008), 2008The concept of retro directive arrays was originated decades ago and various system architectures associated with it have been studied and developed in the past several years. However, the focus of the research so far has been on implementation algorithms and potential applications; although the retrodirective systems have been proposed for uses in ...

A Sub-Terahertz Retrodirective Antenna Array for Satellite Tracking
2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2019A sub-terahertz retrodirective antenna array is proposed. This array receives 40 GHz navigation signal and accurately retransmits 120 GHz beam in the direction of arrival wave. Simulation results indicate that proposed array with stacked sandwich structure has realized the tracking of the arrival wave. The scanning radiation pattern shows array gain is

A New Millimeter-Wave Broadband Retrodirective Antenna Array
2007 IEEE/MTT-S International Microwave Symposium, 2007This paper reported a broadband 8times16 retro-directive array for millimeter-wave applications. The array element is a proximity-coupled dual-ring antenna with a bandwidth of 33.7% (31-42.8 GHz). The antenna is used to build a 4times4 retrodirective array as a sub-array. Then the sub-arrays are assembled to form an 8times16 array. The design method of

Active retrodirective antenna arrays for mobile communication applications
IEE Colloquium on Low Cost Antenna Technology, 1998This paper presents developments of planar active retrodirective antennas based on microstrip technology. The architectures of the retrodirective antennas described in the paper are based on dual frequency operation for transmission and reception. Results for the monostatic radar cross section (MRCS) measurement on two element retrodirective arrays ...

A compact retrodirective wire antenna with two isolated ports
IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004Retrodirective arrays have the unique characteristic that they reradiate an incoming signal back toward the source without a priori knowledge of the arrival direction or reliance on sophisticated digital-signal-processing algorithms. The unique feature makes the retrodirective array an attractive candidate for advanced digital mobile communication ...

Conceptual Architecture of a Retrodirective Antenna System with Beamforming Capabilities
2018 International Conference on Communications (COMM), 2018As antenna arrays can achieve high directivity, they improve the performance of a receiver in terms of signal detection and offer the support for the implementation of advanced techniques like direction-of-arrival estimation, source localization, beamforming and user tracking.

We describe the key ideas behind our implementation of a distributed antenna array fully pre-synchronized for retrodirective transmission to an external receiver. In our implementation, a number of wireless transceivers in a network use a sequence of simple in-band wireless message exchanges to calibrate themselves so that these transceivers can obtain

Multiple target tracking using retrodirective antenna arrays
IEE National Conference on Antennas and Propagation, 1999In this paper the behavioural response of a frequency offset retrodirective antenna array [1 ] in the presence of multiple signals at different frequencies is investigated. It is shown that when separate frequency sources exist, the re-transmited beam of the retrodirective array will split into multiple beams, with each re-transmitted beam forming in ...
