Broadband Inverted L-Shaped DRA for IoT Applications

This paper presents a broadband inverted L-shaped dielectric resonator antenna (DRA) designed to generate omnidirectional radiation for Internet of Things (IoT) applications. The antenna covers the frequency range of 2.4 GHz to 5 GHz, which encompasses the WiFi frequency range. The DRA offers an omnidirectional radiation pattern, making it suitable for various IoT applications. The antenna structure features an asymmetrical placement of an L-shaped dielectric resonator on a substrate, enabling efficient omnidirectional radiation. By optimizing the dimensions of the dielectric resonator and substrate, a compact antenna design is achieved. Simulated results demonstrate the excellent performance of the proposed antenna, showcasing omnidirectional radiation patterns within the frequency range of 2.4 GHz to 5 GHz. The compact inverted L-shaped DRA presented in this study provides a promising solution for efficient omnidirectional beam generation, making it suitable for advanced communication systems that require coverage in all directions.
