1. 1. Phased array antenna element evaluation

   University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

   Author : Jacob Samuelsson; [2017]
   Keywords : Antenna; Array; PIFA; Notch; HFSS;

   Abstract : This thesis evaluates two array antenna elements for large phased array antennas. The two antenna concepts are a surface mounted notch element and a PIFA (Planar Inverted F Antenna). The antennas have been simulated at S-band in Ansys HFSS as a unit cell in an infinite array environment. READ MORE

4. 3. Antenna diversity with opportunistic combining

   University essay from Fysik och elektroteknik; Tekniska högskolan

   Author : Md. Khalilur Rahman; Chuanhui Xia; [2012]
   Keywords : ;

   Abstract : In modern telecommunication technologies, the requirement for signal reliability is higher and higher but fading is the main challenge for signal reliability. Different types of techniques have been studied to mitigate this fading but MIMO (Multiple Input Multiple Output) has been studied extensively in wireless communication systems to overcome small-scale fading, which is an efficient way to improve signal-to-noise and bit error rates.
