Improvement of an octave bandwidth bowtie antenna design based on the analysis of a MIMO efficiency metric in random-LOS
Artikel i vetenskaplig tidskrift, 2017

A multiple-input multiple-output (MIMO) efficiency metric based on the probability of detection (PoD) of data bitstreams is used to improve the design of a self-grounded dual-polarized wideband bowtie antenna over an octave bandwidth. The analysis is based on the ideal digital threshold receiver model for the Zero-Forcing algorithm. The random line-of-sight (Random-LOS) channel model with two orthogonal linearly polarized waves coming from the same angle-of-arrival is considered in the evaluation. The MIMO efficiency performance is presented along with the reflection coefficient, the directivity and the radiation patterns of the antennas. Corresponding spatial throughput coverage patterns based on 2-bitstream MIMO efficiency evaluated at the 95% PoD level are also provided. The loss of orthogonality as well as the power imbalance of the 2-bitstreams has been identified as the main reasons to MIMO efficiency performance degradation in Random-LOS.
