Abstract
SummaryA compact flag‐shaped slotted multiple input multiple output (MIMO) antenna is deliberated in the article for triple‐band applications. The flag‐shaped slotted antenna is built with the help of four radiating patches having rectangular slots and disconnected ground structures. The suggested flag‐shaped slotted antenna can operate in the key frequencies of 2.4, 3.5, and 5 GHz. The antenna elements are oriented orthogonally with each other, such that no external decoupling structures are required to provide isolation. The complete size of the four‐element MIMO is 30*30*1.6 mm3. The minimum isolation between the four flag‐shaped slotted elements is −61, −55, and −47 dB in the operating frequency band of 2.3–2.8 GHz, 3.4–3.9 GHz, and 4.5–5.6 GHz, respectively. The simulated and measured results agree with each other, and they have stable radiation and gain. The MIMO performance parameters are measured, and it is noticed that the envelope correlation coefficient is lower than 0.04 and the diversity gain is 9.99 dB in the considered working frequency bands. The proposed flag‐shaped slotted MIMO is appropriate for WLAN, 5G sub‐6 GHz, and ISM wireless 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.
