Multiband-dielectric resonator antenna for LTE application

摘要

This study presents work carried out on a multiband-dielectric resonator antenna (M-DRA) for long-term evolution (LTE) application. A new stack M-DRA is introduced by using two dielectric resonators of different permittivities, stacked on top of each other. The M-DRA is excited using a coaxial probe. The introduction of a finite planar conducting wall reduces the overall size of the proposed M-DRA. It operates at LTE band-VI (828-880 MHz), GSM 1800/1900 and UMTS 2100 for <;-10 dB. The measurements performed with a fabricated antenna showed good agreement with the simulated results.
