Dual-band metamaterial-inspired small monopole antenna for WiFi applications

Abstract

A simple dual-band metamaterial-inspired small monopole antenna is proposed for WiFi applications. In addition to the regular monopole resonance, the metamaterial-inspired loading is exploited to create a second resonance for the lower WiFi band while maintaining the antenna's small form-factor. The measured S parameters and radiation patterns show that the proposed design is suitable for emerging WLAN applications.
