A Minimized Triangular ? Meander Line PIFA Antenna for DCS1800/WIMAX Applications

A novel multiband Triangular ? Meander Line Planar Inverted - F Antenna (PIFA) has been introduced. The proposed PIFA antenna consists of a triangle shaped meandered ? line radiating patch. The proposed antenna operates in the DCS1800 (1.710-1.880 GHz), Mobile WIMAX (2.5-2.69 GHz) and Fixed WIMAX (3.4-3.8 GHz) bands efficiently. Classic triangular PIFA shows very low bandwidth and also operates in a single frequency band. Therefore, the combination of Meander?Line and PIFA antenna improves the proposed antenna characteristics. It also increases the current path. The proposed antenna is covering the size of 50 × 36 × 9.276 mm and showing the overall gain of 3.028 dB.
