Retrodirective Antenna Systems for Wireless Communications
نویسندگان
چکیده
This paper presents an overview of retrodirective antenna systems developed for use in wireless communications. This multiple antenna system automatically reflects incident radiation in the direction of the source radiator by re-transmitting the phase conjugate of the received signal at each antenna. The overall system behaves as a directional antenna with omni-directional coverage and allows tracking of fast moving targets. The standard approaches to implementing these systems are discussed along with their advantages and disadvantages. Additionally practical design considerations are presented with recommendations for areas of future research.

A Novel Small E–Ring Shaped Monopole Antenna with Dual Band-Notch Function for UWB Wireless Communications
This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

متن کاملA Retrodirective Array with Reduced Surface Waves for Wireless Power Transfer Applications
A one-dimensional, dual frequency, active retrodirective array is proposed for wireless power transfer applications. Microstrip circular patch antennas with four shorting pins are used as array elements to suppress surface waves. The proposed design eliminates undesired coupling between array elements due to surface waves present in conventional microstrip antenna arrays in order to improve arr...
متن کاملDigital wireless sensor server using an adaptive smart-antenna/retrodirective array
A wireless sensor server is developed based on a reconfigurable active smart-antenna/retrodirective array. The system can serve as both a retrodirective array transponder and a smart-antenna receiver simply by changing the frequency of the local oscillator applied to the mixers, enabling it to best utilize its hardware to suit its communication environment. When operating as a direct-conversion...
