Dual band ACS-Fed with Loop resonator Antenna for GPS / WLAN Applications

In this article, an asymmetrical coplanar strip (ACS) fed for dual band radiation is used to construct a new tiny printed antenna with dimensions of 21.57× 25.62× 1.6 mm3 on FR4 substrate. The Proposed antenna consists of a ground plane, monopole, and loop resonator that are fed via the ACS Technique. The radiating element has centre frequencies of 1.23 GHz and 2.73 GHz, respectively, with a -10 dB impedance bandwidth of 1180 MHz (1.18-1.26 GHz) and 2550 MHz (2.55-2.94 GHz). For achieving antenna size reduction, ACS-fed applied with monopole provides topmost resonant frequency at 2.73 GHz and loop resonator generates bottom resonant frequency at 1.23GHz. A prototype antenna has a considerable radiation pattern and is suited to the Global Positioning System (GPS) and Wireless Local Area Network (WLAN).
