IEEE Transactions On Antennas and Propagation, 68(3), 2457-2462. https://dx.doi.org/10.1109/TAP.2019.2943322 | Journal: | IEEE Transactions on Antennas and Propagation | Abstract: | This communication presents an approach to design a beam-steerable dipole array with low radar cross section (RCS). A 2-D periodical array of dipole antennas is colocated with absorptive frequency-selective reflection (AFSR) structures to effectively reduce the out-of-band RCS and maintain high gain at the in-band frequencies. The AFSR structures consist of 3-D bandstop frequency-selective structure (FSS) and pyramidal-shaped absorbers to provide a reflection band for the dipole array with enhanced front-to-back ratio. Compared with the reference array, the radiation performance of the proposed array is maintained with an aperture efficiency of 70% and a measured peak gain of 21.5 dBi. The beam-steering angle is up to ±45°. Meanwhile, more than 10 dB two-sided out-of-band RCS reduction is achieved with a bandwidth of 96.5% and 30% for copolarization and 142% for cross polarization, and the in-band RCS is unchanged. | URI: | https://hdl.handle.net/10356/154632 | ISSN: | 0018-926X | DOI: | 10.1109/TAP.2019.2943322 | Schools: | School of Electrical and Electronic Engineering | Rights: | © 2019 IEEE.
