Abstract
The new technology referred to as substrate integrated waveguide (SIW) is considered to be appropriate for fifth-generation (5G) networks. In the presented work, SIW antenna with two slots was developed at 28GHz for improving the antenna's parameters. The distance between vias was controlled for minimizing the antenna's losses. SIW technology was developed at higher frequency, also has compact size and good performance. Yet, SIW antennas have losses at high frequencies due to the distance between vias. The radiating patch of antenna that is being provided depending on without and with slots. For increasing the antenna's bandwidth and gain, two types of slots—zigzag and straight—were etched onto the patch. Low losses, significantly high gain and efficiency, also overall structural size of 7.11 x 14.8, both without and with slot, were attained with the suggested design. Straight slot as well as zigzag antennas that are suggested resonate at 28 GHz. The measured results have shown that the proposed antenna could provide 95% efficiency, 8.1 dB gain, also huge band-width of at least 3.1GHz at 28GHz. For boosting the antenna's primary parameters, single antenna was transformed into 1x4 array that was simulated as well as measured. SIW antenna is suitable for 5G applications base stations, according to measurement results.
