“…Future wireless communications, sensing, and electronic warfare are increasingly making use of available spectrum in the higher millimeter‐wave (MMW) bands in order to escape the congestion in lower bands. In addition, they must employ opportunistic spectrum access methods in order to operate in crowded and complex electromagnetic spectrum below 6 GHz 1‐3 . Such systems require frequency agility and pattern/polarization reconfigurability to adapt to changing conditions.…”

“…In addition, they must employ opportunistic spectrum access methods in order to operate in crowded and complex electromagnetic spectrum below 6 GHz. [1][2][3] Such systems require frequency agility and pattern/polarization reconfigurability to adapt to changing conditions. Existing or planned spectrum sharing systems include CBRS (3.5 GHz) and "LTE-Unlicensed" (5 GHz ISM band) but massive growth in the demand for wireless spectrum from IoT and machine-to-machine communications will require more spectrum sharing-even in the newly-opened millimeter-wave bands.…”

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.

To help meet the growing demand for wireless data capacity, the United States Federal Communications Commission (FCC) and National Telecommunications and Information Administration (NTIA) define and regulate a spectrum-sharing approach in several radio frequency (RF) bands, with sharing in additional bands expected in the near future. This paper examines the case in which some of the users in the shared bands are government radars, as is the case in the 3.5 GHz Citizens Broadband Radio Service (CBRS) band. This paper surveys topics related to dynamic spectrum sharing (DSS) of RF bands between government radars and communication systems, including spectrum policy, dynamic spectrum access (DSA), dynamic frequency selection (DFS) and frequency assignment, Primary User (PU) protection and privacy, radar-communications interference mitigation, and joint radar-communications system design. The purpose of this paper is to provide readers with a summary of current knowledge of these aforementioned concepts while also providing references so that topics of interest may be studied deeper. The structure of this paper is broken into several topics, where within each topic table(s) provide a survey of the relevant topic. The contribution made includes over 200 references. Tables include summaries of approaches described in multiple references, as well as descriptions and summaries of individual references used throughout the survey. A taxonomy of approaches applicable to spectrum sharing between radar and communication systems is provided, as are conclusions and recommendations. Findings include existing technology, systems, and regulations utilizing the CBRS in its current structure. Therefore, all of the advancements will most likely be derived using a combination, derivative, or adapted methodology defined in the different sections throughout this survey.
