In, a monopole microstrip patch antenna with dimensions of 40 × 20 mm 2 is proposed for WLAN/WiMAX applications, and the corresponding antenna has dual operating bands (3.5 GHz and 5.2 GHz). Recently, Researchers are keen to work in low loss dielectric substrates like Rogers RT/Duroid 5880 because it is suitable to obtain wide bandwidth, stable gain and good radiation patterns. Moreover, microstrip patch antennas are considered as highly efficient for sustaining huge bandwidth, stable gain and high efficiency. Microstrip patch antenna for lower 5G/WiFi/WiMAX applications is widely used due to having a suitable compact size and omnidirectional radiation pattern. After adding internet of things (IoT), the main aim of the future 5G research is to enhance the spectrum related issues, seamless wide-coverage area (100 Mbps user experienced data rate) and super high density control. With the continuous deployment of cellular and mobile communication technology, mobile communication generation is going on 5G technology due to users demand.

Since the time domain, frequency domain and fabricated results are buttressed by each other, the designed π-slotted MPA is one of the best candidates for high speed lower 5G/WiFi/WiMAX communication applications. The MPA shows an omni-directional property over the entire operating frequency band. The current distribution on the surface as well as the input impedance of the π-shaped slotted MPA are also favorable. The VSWR over the entire operating frequency is regarded as 1 < voltage standing wave ratio (VSWR) < 2 and VSWR is 1.0293 at centre frequency 3.47 GHz. The MPA has a wide impedance bandwidth (2600 MHz), high radiation efficiency (90.88%), acceptable gain (2.647 dB) and low return loss (simulated: -36.81, measured: -25 dB). The length ( L) and the width ( W) of the π-slotted antenna are 35 mm and 31 mm respectively, which covers the operating frequency range 2.87–5.47 GHz. The π-shaped slotted MPA is mounted on low loss dielectric material Rogers RT5880 with a height of 0.79 mm and relative permittivity of 2.2. The proposed MPA is optimized and designed by using the computer simulation technology (CST) microwave studio (MWS) suite version of 2018. In this research work, a π-shaped slotted microstrip patch antenna (MPA) with a partial ground structure for lower fifth generation (5G)/wireless fidelity (WiFi)/worldwide interoperability for microwave access (WiMAX) applications is presented.
