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 polarization-controlled MIMO antenna to realize ultra high-speed and high-capacity mobile communications. The proposed antenna is comprised of three orthogonal dipoles, which can be controlled using a weight function created based on the variation of cross polarization power ratio (XPR) and the antenna inclination angle. By adjusting a phase shift between the antenna elements...
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...
