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.

Summary: This paper proposes a compact stepped slot antenna for ultra-wideband applications, achieving a very small size and wide operating bandwidth. By integrating a stepped slot on the back side and exciting it using a 50 omega-feed line on the top side, the antenna demonstrates a large impedance bandwidth. Additional elementary slots are utilized to further increase the operating bandwidth, resulting in an omnidirectional radiation pattern in the H-plane and bidirectional pattern in the E-plane.

Summary: Mechanical antennas based on piezoelectric materials can significantly reduce the size of long wave antennas and improve communication capacity. However, their narrow bandwidth and weak field intensity limit their practical applications. A mechanical antenna based on PMN-PT is proposed to address these limitations and exhibits ultra-wideband characteristics and excellent communication properties.

Summary: Research on a dielectric patch antenna (DPA) that exhibits a wide impedance bandwidth and stable radiation pattern is conducted. Multiple air regions are introduced into the DPA to manipulate the resonant frequencies of different modes, resulting in an enhanced impedance bandwidth. Additionally, these air regions also regulate the E-field distributions of higher order modes, reducing out-of-phase E-fields and improving the radiation pattern. A prototype operating in the X-band was designed, fabricated, and measured to validate the concept, with reasonable agreement observed between measured and simulated results. The measured 10 dB impedance bandwidth is 44.9% (8.3-13.1 GHz) and the peak boresight realized gain is 8.95 dBi, with stable radiation patterns obtained within the working band.
