Slant polarized Multi Input Multi Output MIMO antennas are able to improve the performance of mobile communication systems in terms of channel capacity Specifically the implementation of MIMO configurations for automotive applications requires the consideration of high gain wideband low profile and affordable antennas in the communication link In this work design simulation and measurement of a new dual band slant polarized MIMO antenna with HPBW Half Power Beam Width of around 900 are presented Then four replicas of the proposed antenna set are placed at four different poles North South West and East to cover 3600 around the vehicle in an omni directional pattern In a real world scenario the proper antenna set is selected to communicate with the intended user Each slant MIMO antenna set consists of two inclined 450 low band LB 700 to 900 MHz and two inclined high band HB 1 7 to 2 7 GHz log periodic antennas The measured gain of LB and HB antennas are 7 dBi and 8 dBi respectively Strong correlation between simulation and measurement results confirms the accuracy of the design and simulation procedures of the proposed antenna system obtained using a genetic optimization algorithm The fabricated antenna was also measured in the field for industrial applications
