Bandwidth improvement of T-shaped slotted multiple input and multiple output antenna comparing with double slotted antenna using high frequency structure simulator software

The focus of this study is on developing a new kind of Multiple Input Multiple Output (MIMO) antenna with a slotted rectangular T-shape on a FR4 epoxy substrate, with the goal of increasing bandwidth in the 6–10 GHz range. From 6 GHz to 10 GHz, the bandwidth and frequency of a T-shaped slotted Multiple Input Multiple Output (MIMO) antenna (Group1, n=15) were compared to those of a Single slot MIMO (Group2, n=15) antenna. Maximum allowable error is set at 0.02 percent, and the pre-test power for testing T-shaped Slot and Double slotted antennas is 80 percent. In the region of 6 GHz to 10 GHz, we compared the bandwidth and frequency of a Double slotted MIMO Antenna to that of a T-shaped slot MIMO antenna. Compared to the double-slotted antenna’s 10 MHz bandwidth, the T-shaped slot MIMO antenna’s bandwidth is 100 MHz. Maximum bandwidth was achieved at a frequency of 5.9 GHz with both the T-shaped slot MIMO antenna and the double slot MIMO antenna operating at 10 GHz. In this study, a p-value of 0.991 was reported, which is statistically significant (p>0.05). The T-shaped slot Multiple Input and Multiple Output Antenna improves bandwidth in the 10 GHz region for Ultra-Wideband applications within the constraints of this innovative antenna design.
