  4. 3. Lower bounds on the Q-factor for small oversampled superdirective arrays over a ground plane

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Masahiro Wakasa; [2016]
    Keywords : ;

    Abstract : Base station antennas for next generation mobile communication networks will be required to have a wide bandwidth for compatibility and support multi-beam applications. Antenna arrays are one possible candidate for a next generation base station antenna since they can obtain high directivity, support multi-beam and wide angle scanning. READ MORE
