In this paper, several Terahertz (THz) high-gain planar integrated antenna arrays developed in University of Electronic Science and Technology of China (UESTC) are introduced based on the diffusion welding technology. Thanks to their wideband, high-gain and compact configuration, these types of antenna arrays present excellent candidates for THz multi-gigahertz capacity wireless systems.
In this paper, a modified substrate integrated waveguide (SIW) Rotman lens is proposed to feed several SIW slot array antennas in order to generate multiple focal points. This modified SIW Rotman lens, as a focused beamforming network (BFN), consists of eleven input beam ports and fifteen output array ports. Its phase shifting network is modified to satisfy the requirements of beam focusing and scanning...
The orbital angular momentum (OAM) beam can be used to significantly increase the communication capacity. In this paper, a reflectarray antenna is proposed and demonstrated for generating arbitrary OAM beams. A new dual-resonance dipole element is employed to implement the conversion between the incident spherical wave and the reflected OAM wave. Besides, this element can provide very good polarization...
In this paper, a substrate integrated conformal antenna based on a 3D-printing conical pedestal is demonstrated. This array is mounted on a cone with a radius on the top of 15 mm and a radius on the bottom of 35 mm. It is synthesized at the center frequency of 35 GHz. It is not an easy task to fabricate a non-planar structure, thus the 3D printing technology is used to fabricate the cone. This method...
In this paper, several high-gain planar integrated antenna arrays are overviewed. Thanks to their wideband, high-gain and compact configuration, these types of substrate integrated antenna arrays present excellent candidates for millimeter-wave multi-gigahertz capacity wireless systems.
This paper overviews two types of high-gain wideband planar integrated antenna arrays. Thanks to their wideband, high-gain and compact configuration, these types of substrate integrated antenna arrays present excellent candidates for millimeter-wave multi-gigahertz capacity wireless communication systems.
