1. 1. Antenna Arrays for Dual-Frequency Harmonic Radar Application

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Venkatesh Raja; Mohammad Zafar Mohammad; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. LÄS MER

3. 2. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Natachai Terawatsakul; [2023]
   Nyckelord :;

   Sammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER

4. 3. Design of an Array of Patch-elements With a Band-pass Frequency Selective Surface Hybrid Radome : Analysis and characterisation of a frequency selective surface and a phased array antenna

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Curt-Herman Normark Frisk; [2022]
   Nyckelord :Frequency Selective Surface; Microstrip Patch Element; Circular Polarisation; Phased Array Antenna; Single Feed; Frekvensselektiv Yta; Mikrostrip Patchelement; Cirkulär Polarisering; Fasstyrd Gruppantenn; Single-matad;

   Sammanfattning : A circular polarised phased array antenna and a frequency selective hybrid radome are designed and evaluated. The antenna system is well suited as a part of a communication link between platforms with a 600 MHz bandwidth and a centre frequency of 5 GHz. LÄS MER

5. 4. A Modular Approach to Design and Implementation of an Active GNSS Antenna

   Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Ulrik Hecktor; [2022]
   Nyckelord :GNSS; RTK; circular patch antenna; LNA; stacked patch antenna;

   Sammanfattning : This master’s thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. LÄS MER

7. 5. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Vinodhini Mylai Chandrasekaran; Nikhila Chinnayanapalli Ravi; [2022]
   Nyckelord :Antenna Design; mmWave frequency; 5G; FEKO; Technology and Engineering;

   Sammanfattning : The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and many more such applications.
