Tóm tắt

The paper presents the monopole antenna’s structure, L antenna’s structure, F antenna’s structure and shows developments toward antenna’s structure enhancement. Thus, the paper presents a method to enhance the structure of planar inverted F antenna (PIFA) by meandering and folding techniques for the monopole antenna placed on FR4 dielectric. The proposed PIFA antenna has a compact size (21 × 14.5 × 3 mm3). In addition, this antenna offers enough wide bandwidth 380 MHz (VSWR ≤ 2), which covers 3G band. The authors use the simulation program HFSS of Ansoft to compute the antenna parameters such as input impedance, VSWR, bandwidth and the peak gain. The results from stimulation program show the enhancement of PIFA’s structure to verify its applicability for the 3G devices.
