1. 1. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Johan Kövamees; [2020]
   Keywords : Electrically Steerable Phased-Arrays for 5G Sub-6 GHz Massive MIMO Active Antenna Units;

   Abstract : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. READ MORE

3. 2. Miniaturized quadrature hybrid and rat race coupler utilizing coupled lines for LTE frequency bands

   University essay from Fysik och elektroteknik; Tekniska högskolan

   Author : Masiur Rahman; [2013]
   Keywords : Coupler; quadrature hybrid coupler; rat race coupler; LTE frequecy band; miniaturization; coupled line; microwave communication etc.;

   Abstract : Nowadays, demands for fully integrated and miniaturized RFIC (Radio Frequency Integrated Circuits) have increased in wireless microwave communication system. Passive components such as coupler, divider and filters are always fabricated in outside of ICs due to their bulky sizes, which have been a great barrier to a realization of a fully integrated design.
