We present a new improved design of the self-grounded dual-polarized wideband bowtie antenna for MIMO application. The antenna is evaluated for the case when the original four ports are combined to two orthogonally polarized ports. The new antenna covers the previous bandwidth but has lower gain and wider beamwidth over the frequency band of interest. The 2×2 MIMO performance of the antenna in Random-Line...
We present the design of a new sector reflector antenna with 2-dimensional hat feed in order to avoid the radio link disconnection in point-to-point link communication systems due to the swinging of link antennas when there is a strong wind or vibration. The antenna has a 32% bandwidth for both the reflection coefficient below ™17.8dB and the sidelobes of the radiation pattern in vertical plane below...
In this paper, we propose a linear array configuration for Random Line-of-Sight Over-The-Air testing set-up in anechoic chamber. For this aim, we use the self-grounded dual-polarized bowtie antenna as the element in the array. We present a new design of the bowtie to improve the array performance in terms of reflection coefficient and directivity. The new design has a simpler profile to manufacture...
A simple-to-use replacement model for isotropic electromagnetic bandgap (EBG) surfaces such as mushroom surfaces is investigated. Properties of EBG surfaces strongly depend on the incidence angle of the incoming plane wave. The suggested model takes this behavior into account and actually represents the ideal EBG surface. The model is based on uniaxial representation of a thin DB layer backed by a...
