With a permittivity (ε0) of 4.3 (FR4) and dimensions of 35×43×1 mm3, the author of this article makes a small patch antenna that is sandwiched between a radiating patch and defected ground structure (DGS) plane. The C-shaped antenna is connected to the coaxial cable connection using a microstrip feedline, and the input impedance (50Ω) is matched. The DGS-based antenna was designed to resonate between the bands of frequencies 13.18 - 15.82 GHz (Ku-band), 16.97 - 19.65 GHz (K-Band) and 22.64 - 24.95 GHz (Ka-Band) at resonance frequencies of 14.15 GHz, 18.45 GHz and 23.88 GHz respectively. The voltage standing wave ratio (VSWR) at resonance frequencies of 14.15 GHz, 18.45 GHz and 23.88 GHz is found 1.02, 1.10 and 1.45 respectively, which is less than two (VSWR<2). This patch antenna is being deliberate because it has a low VSWR at each of the three resonance frequencies and has a large bandwidth at −10 dB. For wireless communications, this design is appropriate for triple band operations. Computer simulated tool (CST) software has been used to simulate the electromagnetics properties of the proposed antenna. Proposed antenna provides a triple band with appropriate Gain, VSWR, return loss, and radiation pattern for wireless applications. According to parametric study, this design is suitable for Ka-band, K-band, and Ku-band for wireless applications.
