Abstract
Conference Title: 2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting Conference Start Date: 2015, July 19 Conference End Date: 2015, July 24 Conference Location: Vancouver, BC, Canada A Dielectric loaded millimeter wave antenna array of 1 × 4 elements fed by slotted substrate integrated waveguide for 60 GHz communication systems is presented. Only slotted SIW design cannot provide a wide bandwidth and hence to achieve wide bandwidth the concept of dielectric loading is adopted. The cumulative effect results in wide bandwidth. This design uses a complete SIW feed network to minimize the effect of back radiations. The results show an impedance bandwidth of 10.50 % around 60 GHz, having a gain up to 10.60 dBi, and an estimated efficiency of 75 %. The designs are simulated in CST Microwave Studio and verified in HFSS simulator.
