Multiband hybrid loop-notch antennas
Loughborough Antennas & Propagation Conference (LAPC 2017), 2017 The study describes a small antenna with a hybrid loop‐notch configuration. This format has very small dimensions in terms of the operating wavelength and operation is possible over two or more non‐contiguous frequency bands. When integrated into a host circuit board it can be designed to maintain a substantially constant resonant frequency in the ...

High Voltage, EarlyView.ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.
