CPW-Fed Quad-Band Dual Port Meandered Monopole Automotive Antenna

Abstract

A dual-port MIMO antenna is presented in this paper. It operates at multiple frequencies like 0.9, 2.45, 3.3 and 5.5 GHz. The overall dimension of the presented MIMO is 38×16 mm2 and it is developed on FR-4 substrate. The orthogonal placement of antenna offers dual polarization and good isolation of greater than 15 dB is achieved without any decoupling structures. The antenna is fabricated and required measurements are conducted. The peak gain is found to be 4.34 dBi and maximum efficiency is 97%. The diversity parameter study shows that ECC<0.1, DG>9.88, TARC<-10 dB and CCL<0.1 bits/s/Hz. The antenna is studied for antenna housing effect to know the stability of the antenna in the vehicular environment.
