Analysis of Wideband Millimetre Wave PBG Antenna
Present paper has been set to analyze the effects of PBG structure over a new generation communication systems,
which is in great demand in today’s era. Efficiency and gain improvement are the major concern to enhance the bandwidth to
support multimedia activities properly. Author has analyzed the rectangular antenna structure for wideband applications with
and without PBG material using commercial software CST microwave studio and through coding. Most specific properties
like return loss, VSWR and bandwidth are obtained as high as compared to simple rectangular antenna. Radiation pattern
also supports the analysis in proving effect of single mode over multimode operation.
