Abstract: This study describes the design and implementation of a compact triple-band Dielectric Resonator Antenna (DRA) for Wireless Local Area Network (WLAN) applications. The suggested antenna features a new hybrid dielectric structure consisting of two overlapping hemispherical resonators with radii and separated by a distance. This study introduces a new triple band DRA architecture that is fed by a microstrip line. On a FR-4 substrate, two cut cylindrical dielectric resonators make up the suggested configuration. The microstrip feed line's precise length and positioning are crucial for accomplishing multi-band functioning because they efficiently stimulate three different resonant modes. Triple band operation with severe resonances at roughly 6.57 GHz, 8.01 GHz, and 9.2 GHz is confirmed by the simulated return loss (S11) response, which was acquired via HFSS. Because these frequency bands span a large spectrum, the antenna can be used in a number of high-frequency applications. Its potential for incorporation into future wireless local area network (WLAN) systems and other microwave communication systems is suggested by its small size, effective design, and good performance metrics.
