Abstract
- A novel maze shaped multiband monopole antenna with a miniaturized size of only 6 × 4 × 1.6 mm3 is proposed. To further achieving excellent radiation performances across the desired operating bands, an air‐gap is set between the proposed antenna and system ground. To assess the performances of the antenna, simulations are initially carried out by loading a 1.6 mm thick nonconducting Polycarbonate material (analogous to an air‐gap) between the antenna and system ground, and a simplified equivalent circuit (EC) model of the proposed antenna is also derived. The proposed antenna has excited two different resonance frequencies, in which the lower band (fL) and upper band (fU) can yield broad 10‐dB impedance bandwidths of 6.5% (2.37‐2.53 GHz) and 16% (5.05‐5.90 GHz), respectively. Furthermore, desirable gain and radiation efficiency of 2.85 to 6.40 dBi and 57% to 85%, respectively across the two operating bands were also achieved. A practical experiment is also carried out by installing the proposed antenna into a real laptop computer (L412 Think Pad Lenovo). [ABSTRACT FROM AUTHOR]
