A strategy adopted for reducing radar cross section (RCS) of antenna by utilizing the holographic metasurface (HM), with preserving the radiation performance simultaneously, is proposed and discussed. The scheme is based on implementation of the HM capable of operation over a wide frequency band for both - and -polarized incident waves. By converting propagating waves into surface waves, which...
This paper presents a design method for the Disk-Loaded Monopole stacked with Patch antenna (DLMP) using the print circuit board (PCB). The DLMP has three driven ports, each of which can create independent radiation patterns with orthogonally polarized characteristics. In this antenna, a disk-loaded monopole antenna for Z axis is stacked on a patch antenna for X axis and Y axis radiation. And both...
This paper presents a three-axis decoupling stubloaded parallel dipole array antenna with tri-orthogonal polarization directivity. The decoupling characteristics are realized using the phase shifter composed of a quarter-wavelength stub placed at two sides of three parallel dipole array antenna for creating the opposite phase of the current distribution. Further, the quarter-wavelength stub is operated...
This paper presents a disk-loaded monopole stacked with patch antenna (DLMP) with a low-profile structure. The DLMP has three driven ports, each of which can create independent radiation patterns with orthogonally polarized characteristics. A design example is presented to achieve an overall height of 10 mm at 2 GHz. The calculated results show that the DLMP has well-defined monopole mode and patch...
This paper presents a dual-polarized turn-style patch antenna for BAN on-body communication systems. Our target is aiming at achieving an orthogonally-polarized omnidirectional radiation pattern in the mounting plane of the antenna, which is similar to the turn-style operating principle. The analytical results of a design example show that the desired radiation characteristics can be realized using...
This paper investigates the mutual interactions between MIMO antenna radiation and multipath characteristics to obtain useful knowledge that can be employed in the design of a three-dimensional OTA system. In investigating factors that may affect the MIMO channel capacity, we focus on two key parameters, the incident wave power distribution in the elevation direction and the radiation pattern of terminal...
