  1. 1. Data-driven Interpolation Methods Applied to Antenna System Responses : Implementation of and Benchmarking

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lucas Åkerstedt; [2023]
    Keywords : Model Order Reduction; Loewner Framework; State-space Representation; Nevanlinna-Pick Interpolation; Vector Fitting; Cauchy interpolation; Antenna System Responses; Benchmarking; MoM; Data-driven; Interpolation; Modelordningsreducering; Loewner Ramverk; Tillståndsrepresentation; NevanlinnaPick Interpolering; Vector Fitting; Cauchy Interpolering; Antennsystemsvar; Prestandajämförelse; MoM; Datadriven; Interpolering;

    Abstract : With the advances in the telecommunications industry, there is a need to solve the in-band full-duplex (IBFD) problem for antenna systems. One premise for solving the IBFD problem is to have strong isolation between transmitter and receiver antennas in an antenna system. READ MORE

  3. 2. Dual-polarized feed for mmWave lens antennas

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Juan Luis Albadalejo Lijarcio; [2020]
    Keywords : ;

    Abstract : The fact of being bulky and not very cost-efficient made lens antennas not to be takenmuch into account in the past. Nowadays, this kind of antennas has attracted moreattention due to the increasing demand of higher frequencies in 5G, where lensesbecome considerably smaller. READ MORE

  4. 3. Non-Coherent Radio-Based Positioning

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Farshid Rezaei; Mohamad Abou Nasa; [2019]
    Keywords : target localization and tracking; wireless sensor network WSN ; hybrid measurements; received signal strength RSS ; angle of arrival AoA ; Technology and Engineering;

    Abstract : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. READ MORE

  5. 4. Three orthogonal polarized antenna

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Fredrik Rogberg; [2013]
    Keywords : ;

    Abstract : The demand for wireless communication systems has continued to grow steadily and a number oftechnological advances have been made during this growth. To increase system capacity for wirelesssystems by means of uncorrelated propagation paths, a MIMO (Multiple Input Multiple Output) systemhas been considered a better technology for improving the capacity.
