    Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

  3. 2. Low-dispersive Leaky-wave Antennas: A Viable Approach for Fifth Generation (5G) mmWave Base Station Antennas

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Oskar Dahlberg; [2019]
    Keywords : ;

    Abstract : In this work, a method to achieve reduced beam-squint in fully metallic leaky-wave antennas is proposed and its applicability for high frequency, high gain, base station antennas in future communication networks is indicated. The antenna is built in gap waveguide technology, where the fundamental mode is allowed to leak by removal of one of the waveguide walls. READ MORE

  4. 3. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation & Choosing DPSS Parameters

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Carl-Henrik Hanquist; [2018]
    Keywords : DPSS; Multitaper; Radar;

    Abstract : One of the biggest challenges in any airborne radar is to distinguish a target from a strong ground echo. The main problem is that the ground echo, called ground clutter, can be up to a million times stronger than the response from the target in question. READ MORE
