3. 12. Phase shifter design & Research study and verification of wideband phase shifter circuits

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : JAYAPRAKASH SELVARAJ; [2012]
   Keywords : ;

   Abstract : Radio Frequency waves are widely used for the purpose of radio communication. Active research in Radio Frequency technology has led to the use of RF waves in variety of application other than radio communication. Phase shifters are a major functional block in RF transmission circuits. READ MORE

4. 13. Design and simulation of beam steering for 1D and 2D phased antenna arrays using ADS.

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Muhammad Zeeshan Afridi; Muhammad Umer; Daniyal Razi; [2012]
   Keywords : Phased array; Patch antenna; RF front-end; Beam steering; ADS Momentum.;

   Abstract : Phased arrays eliminate the problems of mechanical steering by using fast and reliable electronic components for steering the main beam. Modeling and simulation of beam steering for 1D and 2D arrays is the aspect that is considered in this thesis. A 1D array with 4 elements and a 2D array with 16 elements are studied in the X-band (8-12 GHz). READ MORE

5. 14. Simulation of Phased Arrays with Rectangular Microstrip Patches on Photonic Crystal Substrates

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Asim Akhtar; Hassan Mateen Alahi; Moeed Sehnan; [2012]
   Keywords : Phased arrays antenna on photonic crystal;

   Abstract : This thesis describes the investigation of photonic crystals as a substrate in microstrip phased array antennas. Alumina with a relative dielectric constant of 9.6 is used as substrate to obtain miniaturization of the components in the high-frequency range. READ MORE

6. 15. Acoustic Beamforming for Hearing Aids Using Multi Microphone Array by Designing Graphical User Interface

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : S S V SUMANTH KOTTA; BULLI KOTESWARARAO KOMMINENI; [2011]
   Keywords : Acoustic Beamforming; Array signal processing; Beam steering; Direction of arrival estimation; Distortion measurement; Interference cancellation; Microphone arrays; Noise cancellation; Speech enhancement.;

   Abstract : Hearing impaired persons lose their ability to distinguish speech signal in ambient noise. Human hearing system is sensitive to interfering noise. Interfering noise decreases the quality and intelligibility of the speech signal which in turn makes speech communication default. READ MORE
