1. 6. Development and tests of SONAR array for underwater communication

   University essay from KTH/Marina system

   Author : Marcus Hellman; [2020]
   Keywords : ;

   Abstract : Water covers about 70 % of Earth’s surface. Most of the water is located in the ocean’s, which have an average depth of almost 3700 meters. This implies that there is a multitude of phenomena to investigate and discover. But due to human limitations other methods and tools need to be considered in order to investigate the depths.

3. 7. 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. 8. Probability of Positive Identification with an IFF E-scan System

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Tora Lutnaes; [2018]
   Keywords : ;

   Abstract : Both military and civil aircrafts depend on a built-in identification system called SSR on a daily basis. IFF is the military adaption of the system for use by fighter jets in order to separate friendly aircrafts from foes but also to coexist with commercial aircrafts. READ MORE

5. 9. Channel Characteristics Variations from Switching Between Narrow Beams

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Oscar Lundberg; [2017]
   Keywords : 5G; radio waves; telecommunication; antennas; beam forming;

   Abstract : The demand for higher throughput and lower latency in telecommunication systems is growing. Upcoming telecommunication systems will operate at higher frequencies (above 15 GHz) compared with previous systems (below 6 GHz). READ MORE

6. 10. Inter-Satellite Link Antennas : Review and The Near Future

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Arttu Tiainen; [2017]
   Keywords : Satellite; ISL; Communications; Antenna;

   Abstract : The emerging trend in distributed spacecraft systems of using multiple spacecraft which share functions as opposed to independent spacecraft has given opportunities for missions previously infeasible. Inter-satellite link (ISL) communications provide a direct link within the space segment without need of an intermediate ground segment to relay the data. READ MORE
