An Array Antenna Based on Substrate Integrated Waveguide Antenna For 5G Application

substrate integrated waveguide (SIW)antenna at millimeter wave is suitable technology, many exciting applications have been made with higher frequency for specific kinds of communication, a wide range of applications, services, and technologies, including short-range communication, future mm-wave mobile communication for fifth-generation (5G) cellular networks, and sensor and imaging systems. Because of the short wavelength, mm-wave frequencies allow for physically smaller antennas and circuits and the availability of a significantly broader bandwidth than microwave frequencies. Because of their extreme sensitivity to atmospheric absorption losses, millimeter-wave antennas must be designed with excellent gain characteristics. Furthermore, Millimeter-wave antennas have a wide bandwidth and are ideal for 5G applications. SIW technology has losses at higher frequencies because of vias. This research creates planar antennas with minimal losses and a high-quality factor by controlling vias of substrate-integrated waveguide (SIW) technology. The proposed design results after modifying a single antenna to an array gain increasing to 11.4dB and directivity of 11.7 dB with a wider bandwidth 1.4GHz.
