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 ...

Antenna showers with one-loop matrix elements [PDF]
Journal of High Energy Physics, 2013 AbstractWe consider the probability for a colour-singlet$ q\overline{q} $pair to emit a gluon, in strongly and smoothly ordered antenna showers. We expand to second order inαsand compare to the second-order QCD matrix elements forZ→ 3 jets, neglecting terms suppressed by$ {1 \left/ {{N_C^2}} \right.} $.

International Journal of Antennas and Propagation, 2017 In this study, the principle of band suppressing an UWB antenna by attaching a small resonator is explained by developing its equivalent circuit. The realized UWB antenna is a conical monopole antenna that contains a split loop for band suppression.
