Standing-Wave Feeding for High-Gain Linear Dielectric Resonator Antenna (DRA) Array. [PDF]
Sensors (Basel), 2022 A novel feeding method for linear DRA arrays is presented, illuminating the use of the power divider, transitions, and launchers, and keeping uniform excitation to array elements. This results in a high-gain DRA array with low losses with a design that is simple, compact and inexpensive.
