Abstract :
In this paper, a new concept for implementation of a miniaturized radio repeater is presented. To construct the radio repeater, two miniaturized low-profile antennas radiating vertical polarization and a thin meta-material channel isolator are integrated in a compact configuration. The overall dimensions of the proposed radio repeater are λo/5.5 x λo/2.7 x λo/70. A commercially available RF amplifier and battery are used to verify the operational feasibility of the repeater. The fabricated repeater was operated with a miniaturized low-power amplifier with more than 30 dB gain.
