Abstract

A coupled-line-based planar antenna for single-band and dual-band operation is presented. The well-known uniplanar coupled inverted-L antenna (UCILA) has a simple and specific mechanism to achieve the dual-band ratio that was not described in the past. The UCILA which shunted a short stub in the slotline portion can provide switchable modes among single-low band (3.4% for WLAN 2.44 GHz), single-high band (15% for WLAN 5.2-5.8 GHz band) and dual-band (WLAN 2.44/5-6 GHz) operations.
