An active retrodirective antenna array

open access: yes, 2011
Retrodirective antenna arrays utilize an array of antennas to redirect a signal back in the direction it originated from without use of digital circuitry, microcontrollers, or sophisticated signal processing algorithms.

Bit error rate performance enhancement of a retrodirective array over a conventional fixed beam array in a dynamic multipath environment

open access: yes, 2010
In this paper, we provide experimental evidence to show that enhanced bit error rate (BER) performance is possible using a retrodirective array operating in a dynamically varying multipath environment.

Retrodirective Harmonic Tag Using Van-Atta Array [PDF]

open access: yes
In this paper, the concept of retrodirective harmonic tag using the Van-Atta array is proposed. Its effectiveness is evaluated through experiments using a 2-element patch antenna for each subset-antenna, where the 2nd harmonics was used for the uplink ...

Properties of circularly polarised spherical retrodirective array

open access: yes
In this paper we provide the first ever discussion of the characteristics of a spherical retrodirective array. The array is populated with planar circularly polarised (CP) microstrip patch antennas.

Retrodirective array radar cross-section performance comparisons

open access: yes, 2000
This paper reports on the comparison of the radar cross-section (RCS) of a 4-element retrodirective array (RDA) calculated from its measured gain with the predicted RCS of a flat plate, and a 90/spl deg/ dihedral corner reflector.
