Abstract
This article represents the design and performance analysis of a compact (36.25 × 34.75 × 0.79 mm3) ultra-wideband (UWB) microstrip patch array antenna having parasitic elements whose operating frequency ranges from 2.77 to 12.85 GHz. The UWB antenna is mounted on Roger’s RT 5880 (lossy) substrate (2.2, 0.0009). The entire design process and simulation is performed by CST. The results of the designed UWB antenna show that the reflection coefficient is −32.8 dB at 3.45 GHz, −35.33 dB at 4.68 GHz, −22.524 dB at 7.78 GHz, and 18.23 dB at 12.09 GHz, gain is 3.92 dB at 4.68 GHz, directivity is 4.55 dBi at 4.68 GHz, and VSWR is 1.0348 at 4.68 GHz. Moreover, the maximum radiation efficiency is 98%. Due to compact size (995.153 mm3) and ultra wide operating band of 10.08 GHz, the designed antenna is a suitable model for many wireless applications including microwave imaging (3.1–10.6 GHz), WiMAX (3.4–3.6 GHz), WLAN, WiFi-5/6 (5.180−5.925 GHz, 5.940–7.075 GHz), and Sub-6 GHz (3.3–4.9 GHz) applications. The designed antenna has a stable radiation pattern with a good gain and efficiency.
