Abstract
This paper presents a compact, frequency-reconfigurable magneto-electric dipole (MED) antenna with aperture-coupled excitation for 5G (n77, n78, n79) and ISM/WLAN (2.4 GHz) applications. At a 1 mm-thick FR4 substrate, the design achieves a better than 85% efficiency and a footprint of 60 × 60 × 12 mm3. Three PIN diodes are used in this study, which makes it dynamically tunable across 4 modes of operation, giving a broadband impedance range of 2.30–5.50 GHz with good pair isolation of 20 dB. Optimized phases in the design lead to better performance with gains varying between 6.70 and 7.05 dBi and better stability. Its cost-effective modularity makes this antenna more appropriate than other non-reconfigurable alternatives for deployment in the advanced networks such as 5G, IoT, and automotive communications.
期刊介绍:
AEÜ is an international scientific journal which publishes both original works and invited tutorials. The journal''s scope covers all aspects of theory and design of circuits, systems and devices for electronics, signal processing, and communication, including:
signal and system theory, digital signal processing
network theory and circuit design
information theory, communication theory and techniques, modulation, source and channel coding
switching theory and techniques, communication protocols
optical communications
microwave theory and techniques, radar, sonar
antennas, wave propagation
AEÜ publishes full papers and letters with very short turn around time but a high standard review process. Review cycles are typically finished within twelve weeks by application of modern electronic communication facilities.
