Ultra‐wideband antenna system for in‐band full‐duplex applications
IET Microwaves, Antennas &Propagation, Volume 15, Issue 15, Page 1853-1865, 16 December 2021., 2021 Abstract In this study, we present an ultra‐wideband full‐duplex system constituted of a wideband 4‐element Vivaldi array and wideband microstrip‐to‐slotline baluns. The proposed system is characterised by its simplicity, high directivity, and high self‐interference cancellation levels over a wide frequency bandwidth.

Liquidity issues: solutions for the asset rich, cash poor
Fiscal Studies, Volume 42, Issue 3-4, Page 651-675, September-December 2021., 2021 Abstract Liquidity concerns are oft raised when considering wealth taxes, yet the issue has received scant attention in the extant literature. In this paper we provide the first comprehensive review of the liquidity problem. Our aims are to estimate the scale of the problem, to explore the extent to which archetypal examples are at risk of experiencing

Gain and Frequency-Selectivity Enhancement of Dual- Polarized Filtering IBFD Antenna Using PRS
Journal of Electromagnetic Engineering and Science, 2023 A dual-polarized filtering Fabry–Perot antenna (FPA) with high selectivity and high isolation is proposed for in-band full-duplex (IBFD) applications. The proposed antenna utilizes a square patch as the feeding element, which is fed by a double differential-fed scheme for dual-polarized radiation with high isolation.

Valuation for the purposes of a wealth tax
Fiscal Studies, Volume 42, Issue 3-4, Page 615-650, September-December 2021., 2021 Abstract This paper considers the scale and prevalence of valuation issues under a wealth tax. Valuation issues are frequently cited in the literature as the most difficult aspect of wealth taxes. We examine some of the most problematic asset types from a valuation perspective.

International Journal of Antennas and Propagation, Volume 2021, Issue 1, 2021., 2021 This paper presents a bi‐port, single‐layered (planar), dual circularly polarized (CP) patch antenna with improved interport isolation for S‐band satellite telemetry and telecommand applications. The dual‐port, planar antenna is based on a square‐shaped radiator with trimmed corner to achieve CP characteristics (RHCP and LHCP) for excitations from ...

Beamforming Design for In-Band Full-Duplex Multi-Cell Multi-User MIMO LSA Cellular Networks
IEEE Access, 2020 The in-band full-duplex (IBFD) mechanism offers many advantages over standard half duplex (HD) systems: it can potentially double the capacity and increase spectrum utilization efficiency. While IBFD renders many conventional research problems irrelevant,
