Design of a Circularly-Polarized UHF Antenna for Partial Discharge Detection
IEEE Access, 2020 In this work, a circularly-polarized ultra-high frequency (UHF) partial discharge (PD) antenna is proposed to detect the PD in 0.6 GHz - 1.7 GHz. The proposed PD antenna consists of an Archimedean spiral antenna, a balun, and a cavity.

An assessment of interference cancellation applied to BWA [PDF]
, 2007 It is a general principle that a communication system should be designed to avoid interference in the first place, either through network planning or with effective radio resource management and medium access control.

An Unbalanced Sinuous Antenna for Near-Surface Polarimetric Ground-Penetrating Radar
IEEE Open Journal of Antennas and Propagation, 2020 Sinuous antennas are capable of producing ultra-wideband radiation with polarization diversity. This capability makes the sinuous antenna an attractive candidate for UWB polarimetric radar applications. Additionally, the ability of the sinuous antenna to

Investigation of Flexible Textile Antennas and AMC Reflectors
International Journal of Antennas and Propagation, 2012 In this paper, two different methods for fabric characterization are presented: a single frequency method and a broadband method. Felt and denim fabrics are characterized, and patch antennas are designed using these substrates to test both methods ...

Trade-off between complexity and BER performance of a polynomial SVD-based broadband MIMO transceiver [PDF]
, 2010 In this paper we investigate non-linear precoding solutions for the problem of broadband multiple-input multiple output(MIMO) systems. Based on a polynomial singular value decomposition (PSVD) we can decouple a broadband MIMO channel into independent ...
