Compact triple-band stacked monopole antenna for USB dongle applications

Abstract

In this article, a novel compact triple-band stacked monopole antenna for USB dongle applications is proposed. The antenna consists of an e-shaped monopole connected directly to the feedline and a square patch-shaped monopole at another layer connected to feedline by a metallic pin. The e-shaped monopole is used to obtain WLAN band (2.4-2.48 GHz) and WiMAX band (3.4-3.69 GHz). On the other hand, square patch-shaped monopole is introduced to get WLAN bands (5.15-5.35 and 5.725-5.825 GHz) and WiMAX band (5.25-5.85 GHz). The antenna is compact with the dimension of 17 × 13 mm2.
