Rectangular strip engraved circular patch and corrugated stub-shaped multiple input multiple outputs (MIMO) antenna designs is numerically investigated, and measurement results are presented in this research for the frequency range of 1 to 25 GHz. It is first numerically investigated to study the various antenna parameters and conduct fabrication on the suggested antenna. We have presented statistics on different antenna parameters for four distinct antenna designs to identify the behaviour in terms of resonating bandwidth, return loss and operating band of the antenna. The proposed antennas are analyzed in terms of their reflectance, gain, and directivity, as well as their efficiency, peak gain, and electric field distribution. With a return loss of − 55.49 dB in simulated results and − 29.89 dB, the rectangular strips engraved corrugated stub antenna can realize the maximum possible bandwidth of 5.49 GHz in simulation and 5.65 GHz in measured outcomes. We have also presented the MIMO antenna parameters ECC, DG, TARC and CCL to identify the antenna behaviour regarding internal interference and efficient signal transmission. In general, the findings obtained from an antenna have the potential to be applied to a wide variety of communication applications, such as those for 5G, WiFi, WiMAX, and satellite communication.
