A circularly polarized (CP) metasurface-inspired antenna array with a low radar cross Section (RCS) over wideband based on polarization conversion metasurface (PCM) is proposed. Without increasing the structural complexity, PCM units serve directly as radiators, which not only maintains good radiation characteristics but also reduces both in-band and out-of-band RCS of antenna. Simulations show that proposed PCM-inspired has an impedance bandwidth 37.6% (8.2–12 GHz), 3 dB axial ratio (AR)...
In this article, a broadband low radar cross section (RCS) circularly polarized (CP) antenna array with reconfigurable scattering patterns is proposed. The comprises 16 elements and phase power divider. element can switch between two states by controlling the of p-i-n diodes, which differ 180° in reflection phase. addition, polarization remains same both but exhibits 90° difference. To compensate for radiation difference, divider based on diodes designed, 0° transmission phases. By output...

A circularly polarized antenna array with reconfigurable scattering patterns is proposed. The proposed unit integrates four p-i-n diodes, enabling the to achieve two operational states by tuning of these diodes. Both exhibit a 180° reflection phase difference but show similar radiation characteristics. Therefore, unit, allows for dynamic manipulation beam without compromising performance, thereby significantly reducing in-band monostatic and bistatic RCS. Finally, units form an 8×8 array....
The challenge of location testing for high-dimensional data in statistical inference is notable. Existing literature suggests various methods, many which impose strong regularity conditions on underlying covariance matrices to ensure asymptotic normal distribution test statistics, leading difficulties size control. To address this, a recent set tests employing the normal-reference approach has been proposed. Moreover, availability R packages implemented C++ limited. This paper introduces...
This paper presents a compact wideband dual-polarized dipole with high isolation. The proposed antenna makes use of two T-shaped orthogonal oscillators to realize the dual-polarization radiation. impedance matching is realized by coaxial slotted balun.
