Phased array antennas for mmWave frequency spectrum for 5G communication

Abstract

We are currently analyzing and simulating an array of antenna with changing phases. Conventional antennas (such as parabolic reflectors) are difficult to move either in azimuth or in elevation, and require more time as they are controlled by servo motors and actuators. On the contrary, the phased array antenna utilizes electronic means to rotate the beam in desired direction. To move or rotate the beam in desired direction, phase of transmitting elements in the array are varied by a device known as phase shifter. Our research mainly focuses on obtaining results in showing that creating an array of antenna and steering the beam in a particular direction is much more efficient in comparison to the conventional method. Moreover, creating an array of antennas can help us to increase the gain compared to a single antenna and we can also move the beam in our desired direction without any mechanical movement of the antenna. Additionally, we worked to change the design of our microstrip patch array element and fruitfully created a key shaped antenna that gives substantially better performance than the original array.
