Phased Array Antenna with Key Shaped Elements for 60 GHz mmWave Communications

the main focus of this paper revolves around analyzing and simulating an array of antenna with changing phases. Creating the array of antennas helped with increasing the gain and directivity as well as reducing side lobes compared to a single element antenna. The results indicate that steering the beam of the antenna array in a particular direction with the help of phase shifters is much more efficient in comparison to the conventional method of using mechanical modes. On a final note, instead of using a conventional microstrip square patch array element, a new and unique key shaped antenna element has been developed that gives substantially better performance than the original conventional array. The design was targeted to operate at 60 GHz for the purpose of vehicular application.
