Narrowband to Narrowband Frequency Tunable Slotted Dipole Antenna

open access: yesJournal of Physics: Conference Series, 2021
Abstract In this paper, the slotted dipole antenna structure is proposed to have four narrowband frequencies with ability to be reconfigured. Narrowband reconfiguration can be achieved by controlling the length of slotted dipole by using switches.

A general weak nonlinearity model for LNAs [PDF]

open access: yes, 2008
This paper presents a general weak nonlinearity model that can be used to model, analyze and describe the distortion behavior of various low noise amplifier topologies in both narrowband and wideband applications.

Ambiguity function and accuracy of the hyperbolic chirp: comparison with the linear chirp [PDF]

open access: yes, 2017
In this paper, we derive the Ambiguity Function (AF) of a narrowband and a wideband hyperbolic chirp. We calculate the second derivatives of the squared amplitude of the narrowband Complex Ambiguity Function (CAF) and use them to calculate the Fisher ...

Infalling Faint [OII] Emitters in Abell 851. I. Spectroscopic Confirmation of Narrowband-Selected Objects [PDF]

open access: yes, 2006
We report on a spectroscopic confirmation of narrowband-selected [OII] emitters in Abell 851 catalogued by Martin et al. (2000). The optical spectra obtained from the Keck I Low Resolution Imaging Spectrometer (LRIS) and Keck II Deep Imaging Multi-Object

First spectroscopic measurements of [OIII] emission from Lyman-alpha selected field galaxies at z ~ 3.1 [PDF]

open access: yes, 2011
We present the first spectroscopic measurements of the [OIII] 5007 A line in two z ~ 3.1 Lyman-alpha emitting galaxies (LAEs) using the new near-infrared instrument LUCIFER1 on the 8.4m Large Binocular Telescope (LBT).

Multi-channel active noise cancellation using the DSP56001 (digital signal processor) [PDF]

open access: yes, 1993
The authors report on the performance of a portable active noise cancellation (ANC) system based around a PC hosted 20-MHz Motorola DSP56001 processor with a four-channel analog input/output (I/O) board connected to the real world via standard consumer ...

Assessment of radio frequency exposures in schools, homes, and public places in Belgium [PDF]

open access: yes, 2014
Characterization of exposure from emerging radio frequency (RF) technologies in areas where children are present is important. Exposure to RF electromagnetic fields (EMF) was assessed in three "sensitive" microenvironments; namely, schools, homes, and ...
