Summary: The study addresses the polarization instability issue at high frequencies in U-slotted wideband antennas by utilizing the TM12 mode in circular patch antennas. The proposed antenna offers stable polarized waves over a wide frequency range and achieves desired impedance and radiation characteristics by integrating U-slots, shorting vias, and non-resonating arc slits. The antenna’s polarization stability is demonstrated through surface current distributions, radiation patterns, and x- and y-polarized gains across the frequency range of interest.

Summary: A wideband differentially-fed slot antenna with circularly polarized radiation is proposed for mmWave applications. A novel method of using stepped corner-shaped slot is utilized to establish wideband CP radiation. The antenna design includes orthogonal radiation and phase delay, as well as modifications to enhance the axial ratio and impedance bandwidth. The antenna element, linear array, and planar array were designed and fabricated to verify performance. Simulated and measured results demonstrate wide overlapped impedance and AR bandwidths for both the linear and planar arrays. Compact size and wide bandwidth make this antenna a promising candidate for mmWave applications.

Summary: This paper introduces an ultrawideband dualpolarized antenna composed of a main radiator, parasitic elements, and a ground plane. The main radiator consists of cross-arranged dual dipoles fed by coplanar-strip lines to achieve +/- 45 degrees dual-polarization within a wide frequency band. Parasitic elements, including a circular patch and four pairs of dipole strips, are used to improve radiation performance in high frequencies. The proposed antenna covers the frequency range from 1.7 to 5.1 GHz for both polarizations, with a gain of 8.2 +/- 0.7 dBi and a half-power beamwidth of 65 degrees +/- 5 degrees. The measured results agree well with simulated ones, indicating its potential for future base-station communication systems.
