Search for: [Description = "A linear 1×4 antenna array built on the Rogers RT\/Duroid 5880 substrate is proposed in this paper to acquire high gain for 5G applications. The proposed design resonates at 38 GHz, i.e. in the Ka\-band region, and has small patch dimensions of 5.5×2 mm. The design is simulated using CST studio. The main element consists of X\-slot that provides a gain of 6.98 dB with the return loss of –24.25 dB whereas a linear array of 4 elements is made which is fed by the 50Ω m\-line using the corporate feeding network which yields a gain of 13.84 dB, as well as the return loss is –15.72 dB. The centreto\-centre spacing \(d\) of elements in the antenna array is 0.8λ"]
