    A compact dual bevel planar monopole antenna with lumped element for ultra high frequency/very high frequency application by Jusoh, Muzammil, Jamlos, Mohd. Faizal, Kamarudin, Muhammad Ramlee

    Published 2012
    “…A planar monopole antenna constructed with 148 mm x 64 mm of radiating element and 80 mm square of ground plane is suitable for cognitive radio (CR) applications where it can cover a very high frequency and a partial of ultra high frequency (UHF) band for spectrum sensing. The proposed monopole antenna is designed by combining a beveling technique and resistor lumped element loading by employing FR4 substrate for low-cost intention. …”

    Intimal and medial arterial changes defined by ultra-high-frequency ultrasound: Response to changing risk factors in children with chronic kidney disease. by Frida Dangardt, Marietta Charakida, Scott Chiesa, Devina Bhowruth, Alicja Rapala, Daniela Thurn, Franz Schaefer, John Deanfield, Rukshana Shroff

    Published 2018-01-01
    “…<h4>Background</h4>Patients with chronic kidney disease (CKD) are exposed to both traditional 'Framingham' and uremia related cardiovascular risk factors that drive atherosclerotic and arteriosclerotic disease, but these cannot be differentiated using conventional ultrasound. We used ultra-high-frequency ultrasound (UHFUS) to differentiate medial thickness (MT) from intimal thickness (IT) in CKD patients, identify their determinants and monitor their progression.…”

    On-Line Partial Discharge Monitoring System for Power Transformers Based on the Simultaneous Detection of High Frequency, Ultra-High Frequency, and Acoustic Emission Signals by Wojciech Sikorski, Krzysztof Walczak, Wieslaw Gil, Cyprian Szymczak

    Published 2020-06-01
    “…The article presents a novel on-line partial discharge (PD) monitoring system for power transformers, whose functioning is based on the simultaneous use of three unconventional methods of PD detection: high-frequency (HF), ultra-high frequency (UHF), and acoustic emission (AE). It is the first monitoring system equipped in an active dielectric window (ADW), which is a combined ultrasonic and electromagnetic PD sensor. …”
