Design and Analysis of a Multi-band Flower Shaped Patch Antenna for WLAN/WiMAX/ISM Band Applications

This paper presents the design and parametric analysis of a flower-shaped patch antenna. The proposed patch antenna is designed using FR-4 substrate mounted on the Jerusalem cross-shaped DGS structure. A Double Negative (DNG) triple Complementary Split Ring Resonator is embedded inside the substrate. A circular foam substrate with the dimensions of 10 × 4 × 10 × 2 mm 3 is sandwiched between the patch and the FR-4 substrate. The overall dimensions of the patch are 23.5 × 16 mm 2 . The proposed antenna resonates at 5.2 GHz and 8.25 GHz respectively. This also possesses wide bandwidth of 1.2 GHz (24.1%) in the range of 4.95–6.15 GHz and 2.2 GHz (26.5%) in the range of 7.1–9.3 GHz. The gains in these bands are observed to be 3.93 dBi and 5.02 dBi respectively. The whole design is carried out in CST-microwave studio 2016 utilizing Finite Integration Technique. The developed multiband antenna can be useful for several wireless communication applications, such as WLAN, WiMAX, and ISM band. The proposed antenna is fabricated and its performance parameters are measured. The simulated and measured results are in good agreement.
