Abstract
This article proposes a novel metasurface patch antenna with characteristics of metasurface and broadband for in-band full-duplex applications, which is configured with a parasitic metasurface, a square patch, two separated feeding networks for transmitting and receiving ports (Tx and Rx), and a square ground. Two feeding networks consist of an antisymmetric L-shaped probe feeding structure for Rx and a double F-shaped feeding structure with a 3 dB/180° hybrid coupler for the Tx port to achieve ±45° polarization and significantly enhanced isolation between the ports. Most importantly, the proposed parasitic metasurface realizes good impedance matching and improves realized gain. Therefore, the proposed antenna attains a −10 dB of overlapped bandwidth of 52.6% through 1.7 to 2.7 GHz with a high isolation of over 41.5 dB. Additionally, the measured gains are 8.9 ± 1.1 dBi for the Rx port and 7.4 ± 0.9 dBi for the Tx port, respectively. These characteristic data all support that the proposed antenna will play an essential role in IBFD applications.
期刊介绍:
The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues.
The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered:
-Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.)
-System control, network/service management
-Network and Internet protocols and standards
-Client-server, distributed and Web-based communication systems
-Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity
-Trials of advanced systems and services; their implementation and evaluation
-Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation
-Performance evaluation issues and methods.
