Abstract
Co-channel interference in wireless networks has a spatial nature due to geographically distributed users in the coverage area and has to be suppressed using beamfoming techniques to achieve higher spectral and power efficiencies. Beamforming with conventional center-fed dipole arrays has several drawbacks such as low array gain, low spatial selectivity due to wide main beamwidths and possibility of occurence for grating lobes due to spatial aliasing.
