Journal of Sensor and Actuator Networks, 2023 A compact circular structured monopole antenna for ultrawideband (UWB) and UWB dual-band notch applications is designed and fabricated on an FR4 substrate. The UWB antenna has a hybrid configuration of the circle and three ellipses as the radiating plane

General relation for group delay and the relevance of group delay for refractometric sensing [PDF]
Journal of the Optical Society of America B, 2014 The relevance of our definition for sensitivity in refractometric sensing, being the relative change in the transmittance of a certain output channel of an optical device over the change in the refractive index of the probed material, is discussed. It is compared to one based on spectral shift per refractive index unit change.

Estimating partial group delay [PDF]
Biometrika, 1989 The partial group delay between two channels of a multiple time series has an interpretation as the time lag between frequency components of the two channels after adjustments have been made for the influence of the remaining channels. A procedure for estimating partial group delay is proposed, and conditions for consistency and asymptotic normality of

Electrical, Control and Communication Engineering, 2020 A novel design of ultra-wideband CPW-fed compact monopole patch antenna is presented in the article. The size of the antenna is 22 × 18 × 1.6 mm and it operates well over an ultra-wideband frequency range 4.86–13.66 GHz (simulated) and 4.93–13.54 GHz ...

Group delay and phase delay in GNSS systems
Geo-spatial Information Science, 2013 GNSS signals have previously been modulated using binary phase shift keying but this modulation scheme is being replaced by binary offset carrier (BOC) modulation. Research has considered how the BOC signals might be affected differently when passed through a surface acoustic wave (SAW) filter.

Optics Express, 2013 We developed a method for group delay and group delay dispersion measurements, based on location of interference resonance peaks. Such resonance peaks can be observed in transmittance or in reflectance when two mirrors are placed parallel to each other and separated by a thin air spacer.
