This paper presents the design and analysis of a miniaturized dual L-shaped inverted to each other dual-band monopole antenna intended for 5G and wireless communication applications. The proposed antenna, with compact dimensions of 20×20×1.6 mm3, operates in two frequency bands (3.2-3.6 GHz)/3.5GHz and (6.0-6.6 GHz)/6.5GHz. These frequency bands are critical for 5G technology, ensuring high-speed data transfer and improved network efficiency. The antenna achieves bandwidths of 11.7% and 9.3% for the lower and upper bands, respectively, offering robust performance and adaptability in diverse wireless communication scenarios. The design employs a dual L shape inverted to each other configuration with truncated L shaped ground plane to achieve the desired miniaturization and dual-band functionality. The antenna's performance metrics, including return loss, gain, and radiation patterns, demonstrate its suitability for integration into compact wireless devices, thereby advancing the development of efficient and space-saving 5G communication systems.
