Abstract
A compact horn-slotted coplanar waveguide (CPW) fed dual-band dual-sense circular polarization antenna is proposed. The antenna resonates with right-handed circular polarization in the lower frequency band and left-handed circular polarization in the upper frequency band. It has a novel horn-shaped slot and a CPW-fed inverted L-shaped active patch. The inverted L-shaped patch with a slanted stub at its right side provides dual-band dual-sense circular polarization characteristics. It has a compact geometry of 0.27 λ0 × 0.27 λ0 × 0.017 λ0, with wideband circular polarization characteristics extending from 2.92 to 3.67 GHz (22.82% of ARBW) and 5.2–5.73 GHz (9.5% of ARBW), thereby covering 5G and WLAN applications, respectively.
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.
