DESIGN OF ANTENNAS FOR HYBRID FSO/RF TRANSMISSION SYSTEM [PDF]
Acta Electrotechnica et Informatica, 2021 The purpose of this publication is to create and correctly analyse a secondary RF line for a hybrid FSO/RF system. Since we want to ensure almost 100% functionality, the design of a secondary RF line is very important.

A Method for Tailoring the Gain Pattern of a Single Antenna Element
IEEE Open Journal of Antennas and Propagation, 2021 In this paper, we present a novel method to tailor the radiation pattern of an antenna element, such as a single element of an array, by maximizing its partial radiation efficiency in the desired angular space.

Power balance and efficiency of metasurface antennas [PDF]
Scientific Reports, 2020 AbstractThis paper presents two methods for the efficient evaluation of the power balance in circular metasurface (MTS) antennas implementing arbitrary modulated surface impedances on a grounded dielectric slab. Both methods assume the surface current in the homogenized MTS to be known.

Multiplexing Efficiency of MIMO Antennas [PDF]
IEEE Antennas and Wireless Propagation Letters, 2011 A simple and intuitive metric of multiplexing efficiency is proposed for evaluating the performance of multiple-input-multiple-output (MIMO) antennas in the spatial multiplexing mode of operation. Apart from gaining valuable insights into the impact of antenna efficiency, efficiency imbalance, and correlation on multiplexing performance, the metric is ...
