Abstract
This paper proposes a compact Multiple Input Multiple Output (MIMO) antenna with frequency reconfigurability for Wi-Fi and fixed satellite applications. Utilizing two PIN diodes, the antenna can switch between (2.14\(-\) 2.98) GHz and (6.66 \(-\) 7.16) GHz electronically. An inverted F-shaped defective ground arrangement ensures excellent isolation between the rectangular antenna elements. Constructed with a low-cost FR4 substrate, the antenna exhibits isolation greater than 25 dB and ECC less than 0.08 over the two frequency bands. At 2.45 GHz and 6.91 GHz, the transducer’s peak realized gains are 4.68 dBi and 4.27 dBi, respectively. The Mean Effective Gain (MEG) and measured Envelope Correlation Coefficient (ECC) make it suitable for MIMO antenna systems. The fabricated prototype validates the proposed concept, with simulation findings closely aligning with measurement results.
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.
