Efficient Analysis of Structures with Rotatable Elements Using Model Order Reduction
(Společnost pro radioelektronické inženýrství, 2016-04)This paper presents a novel full-wave technique which allows for a fast 3D finite element analysis of waveguide structures containing rotatable tuning elements of arbitrary shapes. Rotation of these elements changes the ... -
A Centralized Processing Framework for Foliage Penetration Human Tracking in Multistatic Radar
(Společnost pro radioelektronické inženýrství, 2016-04)A complete centralized processing framework is proposed for human tracking using multistatic radar in the foliage-penetration environment. The configuration of the multistatic radar system is described. Primary attention ... -
Error Analysis of Fixed-Gain AF Relaying with MRC Over Nakagami-m Fading Channels
(Společnost pro radioelektronické inženýrství, 2016-04)This article investigates the error performance of wireless communication systems that employ binary modulations and Amplify-and-Forward (AF) relaying over flat Nakagami-m faded links with maximum ratio combining (MRC) at ... -
SCRLH-TL Based Sequential Rotation Feed Network for Broadband Circularly Polarized Antenna Array
(Společnost pro radioelektronické inženýrství, 2016-04)In this paper, a broadband circularly polarized (CP) microstrip antenna array using composite right/left-handed transmission line (SCRLH-TL) based sequential rotation (SR) feed network is presented. The characteristics of ... -
A Dual Layer Frequency Selective Surface Reflector for Wideband Applications
(Společnost pro radioelektronické inženýrství, 2016-04)A dual-layer, bandstop frequency selective surface (FSS) is presented in this paper for wideband applications. Each layer uses patch type FSS with slots for miniaturization and are cascaded with an air gap in between. The ... -
Multiband Bandstop Filter using an I-Stub-Loaded Meandered Defected Microstrip Structure
(Společnost pro radioelektronické inženýrství, 2016-04)This paper presents a compact multiband bandstop filter (BSF) that utilizes an I-stub embedded within a meandered defected microstrip structure (MDMS). The proposed design for obtaining a single stopband is analyzed by ... -
Analysis and Comparison of new Downlink Technologies for Earth Observation Satellites
(Společnost pro radioelektronické inženýrství, 2016-04)New generation of Earth observation sensors are creating an increasing amount of data which has to be delivered from space-to-ground. Additionally, many applications require timely availability of this sensor data. As new ... -
An Introduction to the Source Concept for Antennas
(Společnost pro radioelektronické inženýrství, 2016-04)Antenna parameters particularly relevant to electrically small antenna design are reviewed in this paper. Source current definitions are accentuated leading to the introduction of the source concept which advantageously ...
