The proliferation of the wireless market has driven the demand for RF systems to dramatically increase functionality, frequency coverage, bandwidth, and efficiency; while simultaneously reducing power consumption and die size to save power and cost. For example, the highly complex RF systems in handset technology have seen a dramatic increase in frequency, operating bands, and complexity of signals with each generation (from 1G to 4G). The next generation (5G) will continue the trend to extend the frequency in to mm-waves due primarily to spectrum congestion, bandwidth, and data rate. DoD is facing comparable challenges in terms of increasing the frequency of operation, bandwidth, and functionality while maintaining cost and accelerating technology insertion (or time to market for commercial). This paper reports on the impact of these new challenges for RF components and discusses solutions under investigation.

“…The CR relies upon two underlying technologies: a frequency agile radio (e.g., a software defined radio [SDR]) and an antenna capable of operating over a wide tuning range. While significant strides have been made in frequency agile radios, [7][8][9] the programmable antenna remains a challenge because the operating frequency and radiation characteristics (polarization, pattern, bandwidth) derive from the antenna geometry which is fixed at fabrication time.…”

In this article, we demonstrate a reconfigurable antenna concept based upon a film of vanadium dioxide (VO2) with embedded metallic surface inclusions to increase radiation efficiency. We fabricate a monopole antenna with the proposed film, demonstrate a good match between measurement and simulation, and propose methods for increasing performance. We show that the addition of metallic inclusions in the VO2 film results in a 37‐fold increase in the radiation efficiency. This concept, if paired with a spatially addressable micro‐heater array, could enable extremely flexible and low‐loss frequency‐agile cognitive radio antennas for dynamic spectrum applications as well as polarization and pattern reconfiguration for operation in 5G and beyond systems where spectrum is congested and coexistence is compulsory.

“…Reconfigurable RF electronics provide adaptability to fielded commercial and military systems [4]. They could also facilitate the research and development (R&D) of future systems by expediting rapid circuit prototyping and reducing non-recurring engineering expenses [5,6]. State-of-the-art approaches to system-level RF reconfigurability rely on some form of switch matrices.…”

“…State-of-the-art approaches to system-level RF reconfigurability rely on some form of switch matrices. One approach uses large heterogeneous networks of RF-switch matrices to select RF components within banks [5], and another uses a monolithic RF-integrated circuit (RF-IC) implementation of arrayed RF blocks embedded in a transistor-level switch fabric [6]. However, these approaches have drawbacks.…”

As an alternative to highly constrained hard-wired reconfigurable RF circuits, a motion-enabled reconfigurable circuit (MERC) offers freedom from transmission line losses and homogeneous materials selection. The creation of a successful MERC requires a precise mechanical mechanism for relocating components. In this work, a piezoelectric MEMS actuator array is modeled and experimentally characterized to assess its viability as a solution to the MERC concept. Actuation and design parameters are evaluated, and the repeatability of high quality on-axis motion at greater than 1 mm s−1 is demonstrated with little positional error. Finally, an initial proof-of-concept circuit reconfiguration has been demonstrated using off-the-shelf RF filter components. Although initial feasibility tests show filter performance degradation with an additional insertion loss of 0.3 dB per contact, out-of-band rejection degradation as high as 10 dB, and ripple performance reduction from 0.25 dB to 1.5 dB, MERC is proven here as an alternative to traditional approaches used in reconfigurable RF circuit applications.
