Additively manufactured frequency selective surface for gain enhancement of sub‐6 GHzmonopole antenna

Abstract

This article demonstrates the advantages of prototyping microwave components using additive manufacturing (AM) technologies. For corroboration, a frequency selective surface (FSS) with meandered square loop and a monopole antenna are manufactured using AM and printed circuit board (PCB) technologies. The performance of these prototypes designed for sub-6 GHz applications are comparatively analyzed. A parametric study further

Design of a Flexible Cylindrical Antenna with Rotatable Curved Frequency Selective Surface for Omnidirectional High-Gain Applications

“…Antenna gain is very important to the operational quality of the wireless communication system. To enhance the gain of antennas, artifcial electromagnetic structures such as artifcial magnetic conductor (AMC) [9,10] and frequency selective surface (FSS) [11][12][13][14][15] are proposed as refectors of antennas. FSS as a spatial flter [16] exhibits diferent scattering characteristics for electromagnetic waves with diferent frequencies.…”

“…Band-stop FSS has total refection characteristics at resonant frequency, and it is widely used in refectarray. Retnam et al [13] used FSS as a back refector to improve the antenna gain, and an improvement of 3 dBi gain over the operational frequency range of 3.07-3.74 GHz was observed. Devarapalli et al [14] presented a coplanar waveguide fed elliptical-based second iterative antenna.…”
