Miniaturized ± 45° dual-polarized meta-surface antenna that utilizes quasi-fractal slot loading technology, aimed at applications requiring both high-efficiency and compact design. The antenna supports dual-polarization by emitting electromagnetic waves at ±45° angles, which enhances signal diversity crucial for modern wireless communication systems, including 5G and IoT applications. Its design is based on a meta-surface constructed from micro-strip-fed square patches arranged in a 3 3 grid, optimized through numerical simulations to maximize performance. Operating at a frequency of 5.6 GHz, the antenna achieves significant miniaturization and a low-profile form factor, making it ideal for integration into portable electronics and constrained environments. Performance analysis indicates improved gain due to the intricate quasi-fractal slot configurations, while advanced electromagnetic modeling validates its balanced radiation patterns and consistent impedance characteristics. Potential future applications could also explore the antenna’s efficacy in real-world scenarios, resilience under various environmental conditions, and manufacturability through cost-effective production techniques. The results are: radiation pattern occurs in 45° co-polarization, the VSWR is 1.2, the S11 =– 22.14 dB, and the gain = 6.01dB. Overall, this innovative design addresses the pressing need for compact yet powerful antenna solutions in contemporary communication technologies.
