Abstract

A novel broadband water-based Fabry–Pérot (FP) antenna with beam-steerable technology is proposed. The antenna consists of a water-based reconfigurable partially reflective surface (RPRS) and a source antenna. The proposed water-based RPRS has 13 columns of microfluidic channels inside. The water-based RPRS achieved 1-D beam steering by regulating phase distribution through the injection of water into its microfluidic channels. The antenna has exhibited a 10-dB impedance bandwidth from 5.07 to 6.46 GHz (a fractional bandwidth of 24.1%). This design achieves a beam steering from −11° to +11° in the elevation plane, with measured realised gains over 10 dBi. To verify the correctness of the design, an antenna prototype was fabricated. The measured results are in good agreement with the simulated results, confirming the accuracy of the design principle. The measured results demonstrate that the main beam of the antenna prototype tilts to −12° in the broadside direction.

期刊介绍: Topics include, but are not limited to: Microwave circuits including RF, microwave and millimetre-wave amplifiers, oscillators, switches, mixers and other components implemented in monolithic, hybrid, multi-chip module and other technologies. Papers on passive components may describe transmission-line and waveguide components, including filters, multiplexers, resonators, ferrite and garnet devices. For applications, papers can describe microwave sub-systems for use in communications, radar, aerospace, instrumentation, industrial and medical applications. Microwave linear and non-linear measurement techniques. Antenna topics including designed and prototyped antennas for operation at all frequencies; multiband antennas, antenna measurement techniques and systems, antenna analysis and design, aperture antenna arrays, adaptive antennas, printed and wire antennas, microstrip, reconfigurable, conformal and integrated antennas. Computational electromagnetics and synthesis of antenna structures including phased arrays and antenna design algorithms. Radiowave propagation at all frequencies and environments. Current Special Issue. Call for papers: Metrology for 5G Technologies - https://digital-library.theiet.org/files/IET_MAP_CFP_M5GT_SI2.pdf
