Abstract
The potential of polylactic acid (PLA) material as an ultra-wide band (UWB)-dielectric resonator antenna (DRA) created by 3D-printing technique are described in this scientific paper. PLA is an exceptional sort of biodegradable thermoplastic composite material having the dissipation factor (tanδ) of 0.05 and dielectric constant (e $${}_{\mathbf{r}}$$ ) of 3.47. Easily available as well as low-cost PLA based Dielectric Resonator Antennas (DRAs) of conventional geometries i.e., Rectangular DRA (RDRA), Cylindrical DRA (CDRA) and Triangular DRA (TDRA) have been explored and developed for broadband societal applications. These three definite constructions of the 3D assembly are utilized to demonstrate the attributes of the PLA as a DRA. Proposed structures of DRAs attain the wide bandwidth of 81.98%, 83.42% and 71.23% for RDRA, CDRA and TDRA respectively for |S11|< −10 dB. The average value of accomplished peak gain is ~ 4 dB for rated maximum frequency band. Therefore, proposed DRAs have an assortment of social utilization in C-, X- and Ku band, for example, climate checking, airport regulation and electromagnetic sensor.
