Abstract
A novel, compact, and flexible dual-band ring-shaped radiating antenna with coplanar waveguide (CPW) feed is proposed for 5G applications. The radiating elements are printed on top of substrate with dimension 29 × 21.3 mm2 and a compact radiating structure is obtained by setting the width of main radiating element and signal strip that are same. To enhance the radiation characteristics of lower and upper band, two rectangular stubs are used. The flexibility of antenna is examined by a convex E-plane bending with radius of 50 mm. The simulated and fabricated antenna have good matching results (bend antenna and without bend antenna). The measured result produces a 10-dB impedan2ce bandwidth of 1.35 GHz (3.17–4.52 GHz) for lower band and a 1.59 GHz (5.71–7.30 GHz) for upper band for covering all 5G bands in lower and upper 3.5 GHz, lower and upper 6 GHz.
期刊介绍：
Analog Integrated Circuits and Signal Processing is an archival peer reviewed journal dedicated to the design and application of analog, radio frequency (RF), and mixed signal integrated circuits (ICs) as well as signal processing circuits and systems. It features both new research results and tutorial views and reflects the large volume of cutting-edge research activity in the worldwide field today.
A partial list of topics includes analog and mixed signal interface circuits and systems; analog and RFIC design; data converters; active-RC, switched-capacitor, and continuous-time integrated filters; mixed analog/digital VLSI systems; wireless radio transceivers; clock and data recovery circuits; and high speed optoelectronic circuits and systems.
