Multi-standard miniature antenna for smart wireless handheld devices application

In this paper, a new design of a miniature multiband antenna for small and low-profile wireless handheld devices is proposed. The proposed system operates in several communications standards WIFI (2.4-2.5GHz), LTE2500 (2.52.7GHz), HyperLAN2 (5.35-5.725GHz) and ISM (5.7255.825GHz) bands. Mounted on a small circular ground plane, of a radius of 20mm, the proposed antenna presents good radiation performance over all the operating bands.
