CPW-fed octagonal-shaped metamaterial-inspired multiband antenna on frequency selective surface for gain enhancement


This paper presents a novel CPW-fed octagonal-shaped metamaterial-inspired antenna on frequency selective surface (FSS) for multiband operations which is suitable for 5G mobile communications and satellite applications. The proposed monopole antenna has the dimensions of 30 × 30 × 1.6 mm3 on FR4 material for the designed resonant frequency of 4.5 GHz. An octagonal-shaped metamaterial unit cell is introduced on the antenna for the other resonant frequencies at 1.7 GHz and 3.4 GHz and the gain achieved only by the antenna without FSS is 2.5 dBi. To enhance the gain, an FSS is proposed as a reflector to the antenna. It acts as a good reflector and enhances the gain upto 8.2 dBi. The angular stability of the FSS unit cell is analyzed with TE and TM polarization and found as 50°. Antenna parameters such as return loss, gain, radiation pattern and transmission/reflection coefficients are observed by the high-frequency structure simulator (HFSS) simulation software and all the results are compared with the experimental measurements.
