A Miniaturized High Fractional Bandwidth Microstrip Antenna for Wide-Band Application

This scholarly work presents the design of a compact microstrip antenna for transmitting and receiving signals. The antenna is optimized using parametric analysis and simulated using HFSS 15 on a 1.6-mm FR4 substrate with a dielectric constant 4.4 and a tangent angle of 0.02. It offers a wide impedance bandwidth of 8.5 GHz to 19.6 GHz, with a fractional bandwidth of 79%. The reflection coefficient of the antenna is remarkable, with values of -66.61 and -46.20 dB, and it has a gain of 3.42 dB. Its radiation patterns, both in the E- and H-plane, are observed, and it is suitable for wireless communication. The proposed antenna is ideal for various applications, including mobile communication devices, wireless networks, and satellite communication systems.
