Development and study of 28 GHz antenna for different shapes and work on antenna transparency for cellular devices

Abstract

In this paper antenna concept is especially presented for future wireless communication devices (smartphones) to achieve spherical beam steering coverage. It also describes a feasibility study performed on antennas made from various transparent conductors. An opaque antenna array in which the radiating elements are simply demonstrated visible and coupled with the cell phone glass is proposed as a solution for saving huge PCB (printed circuit board) spaces. According to the requirement of 5G network communication technology antenna should be functional at 28Ghz frequency with optimal output which is one of the major challenges in terms of design. Thus, in this paper using some specific transparent substrates it is represented to scrutinize the configuration of rectangular, circular antenna arrays fed by a 28 GHz microstrip feeding line for future 5 G applications. Our simulation (using ANSYS HFSS) gives a maximum result for antenna gain of 1X4 circular patch antenna array which is 8.2460dB, moderate return loss of -6.25dB and also have an efficiency of 99.69% using glass substrate whose transparency is 88%.The simulated results of the return-loss, the gain, directivity, electric field, efficiency and radiation pattern of the antenna array is being discussed.
