The paper proposes a microstrip-fed Triangular Dielectric Resonator Antenna (TDRA) for 2.45 GHz frequency. Alumina is used as dielectric resonator having dielectric constant (er) of 9.8. The microstrip coplanar loop feeding mechanism is etched on the topside of FR402 substrate and dielectric resonator is placed on it. The proposed geometry achieves the return loss |s11| < 10 dB from 2.41 GHz to 2.52 GHz. The experimental results showed peak gain of 5.6 dBi at 2.46 GHz resonance frequency. The measured results are well in agreement with simulated results.


In the last few decades, the Dielectric Resonator Antenna (DRA) has become the area of interest because of its attractive features such as compact size, lightweight, low metallic losses, high radiation efficiency, wide bandwidth and low cost. DRAs are available in different shapes (Long et al., 1983; Petosa and Ittipiboon, 2010; and Huynh et al., 2011). But research on Triangular DRA (TDRA) is meager. TDRA has some advantages like simple comprehensive design, smaller area than any other DRAs for given resonant frequency and variable aspect ratios. In addition to this, there is no conducting material excluding feed line, so negligible metallic (conducting) losses exist (Lo and Leung, 1999 and 2001; Leung and Chow, 2003; and Maity and Gupta, 2016). Also, DRAs have high dielectric strength, hence antenna can operate in a wide temperature range.
