“…The high impedance characteristics of AMC have been used to lower the out-of-band RCS of microstrip patch antenna. 9 Also, authors illustrated performance enhancement of an AMC-backed antenna in References 10-14 Various electromagnetic applications of AMC have been discussed in Reference 15. Several other techniques are reported in the literature for gain enhancement of microstrip patch antenna.…”

This work proposes a novel compact artificial magnetic conductor (AMC) surface backed microstrip antenna of dimension (0.29λ 0 Â 0.17λ 0 Â 0.015λ 0 ) for improving the antenna radiation characteristics. The microstrip antenna considered here for performance improvement has a defected ground plane; thus, giving rise to undesired back-lobe radiation. Thanks to the, in-phase reflection characteristics of the AMC surface, gain improvement of more than 3 dBi has been achieved with a front-to-back lobe ratio improvement of 12 dB. This structure resonates at 5.8 GHz with an impedance bandwidth improvement of 13%. The overall antenna dimensions are (0.67λ 0 Â 0.8λ 0 Â 0.13λ 0 ), where λ 0 is the free space wavelength. To prove the concept, a physical prototype of the proposed antenna structure has been fabricated and the return loss, radiation pattern and gain have been verified. The obtained results are satisfactory and matching with the estimated results.

This article proposes a design of a microstrip patch antenna with reduced radar cross‐section (RCS) in a wide frequency band. The RCS of the patch antenna is reduced with the integration of an optimised coding metasurface. The coding metasurface is designed by placing artificial magnetic conductor (AMC) unit cells together to achieve a phase difference between 180 ± 37° within a wide frequency range. The out‐of‐band RCS for the proposed patch antenna is reduced >7 dB from 12.2 to 19.8 GHz, corresponding to a relative bandwidth of 48%, with a maximum reduction of 20 dB at 18 GHz. The operating frequency of the proposed antenna is 8.7 GHz and the RCS reduction is mainly in the Ku band. Both monostatic and bistatic RCS performance of the proposed patch antenna have been simulated and studied. The radiation performance of the proposed patch antenna is hardly influenced by the employment of the proposed coding metasurface. Details of the design considerations along with the simulation and measurement results are presented and discussed. The measured results are in a good agreement with the simulated ones, verifying the validity of the proposed antenna.
