A 2-D Planar Circularly Polarized Van Atta Retrodirective Array With Highly Symmetrical Circular Structure for RCS Enhancement
A 2-D circularly polarized Van Atta array operating in the
X
-band is proposed in this letter. Targeting applications with circular array surfaces, a circular deployment is introduced for the first time. Compared to conventional square deployments, this arrangement allows for more array elements and better symmetry. A 24-element Van Atta array phase conjugate network design is completed based on this circular deployment. The network layer is single layered, ensuring that the phase difference between transmission lines is less than 9.45
$^\circ$
. It exhibits a good enhancement in the orthogonal direction of monostatic radar cross-section (RCS). The −10 dB beamwidths of the measured normalized monostatic RCS are 106
$^\circ (\varphi =0^{\circ }$
) and 94
$^\circ (\varphi =90^{\circ }$
) at 9.4 GHz, 109
$^\circ (\varphi =0^{\circ }$
) and 105
$^\circ (\varphi =90^{\circ }$
) at 9.7 GHz, and 99
$^\circ (\varphi =0^{\circ }$
) and 93
$^\circ (\varphi =90^{\circ }$
) at 10 GHz, which are in good agreement with the simulated results.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
