This article presents a design and analysis of novel offset feed annular ring dielectric resonator antenna for bandwidth increment technique. The proposed antenna design consists of a square-shaped question mark feed with an annular ring. The proposed design generates triple-band characteristics by changing the feed width. The proposed design operates in the following frequency bands 2.2-2.7 GHz, 3.13-3.94 GHz & 5.7- 7.15 GHz with corresponding bandwidth of 22%, 23%, 21%. The applications of the proposed antenna are like Wi-Fi (2.4 GHz), mobile broadband, broadband radio service (3.5 GHz), Radars, commercial WLAN (6.8 GHz).
