Abstract
A significant portion of communication devices employs microstrip antennas because of their compact size, low profile, and ability to conform to both planar and non-planar surfaces. To achieve this, we present a miniature inset-fed rectangular patch antenna using partial ground plane for Ku band applications. The proposed antenna design used an operating frequency of 15.5 GHz, a FR4 substrate with a dielectric constant of 4.3, and a thickness of 1.4 mm. It is fed by a 50 Ω inset feedline. Computer simulation technology (CST) software is used to design, simulate, and analyze. The simulation yields the antenna performance parameters, including return loss (S11), bandwidth, VSWR, gain, directivity, and radiation efficiency. The simulation findings revealed that the proposed antenna resonated at 15.5 GHz, with a return loss of -22.312 dB, a bandwidth of 2.73 GHz (2730 MHz), VSWR of 1.17, a gain of 3.843 dBi, a directivity of 5.926 dBi, and an antenna efficiency of -2.083 dB (61.901%).
