Compact, Printed, Tri-Band Loop Antenna With Capacitively-Driven Feed and End-Loaded Inductor for Notebook Computer Applications

open access: yesIEEE Access, 2018
The shorted monopoles and the planar inverted-F antennas have been utilized for wireless local area network (WLAN) notebook applications for years. This paper presents an alternative and yet promising antenna type with a compact and smaller size of 5 mm &

Pointing a ground antenna at a spinning spacecraft using Conscan-simulation results [PDF]

open access: yes
The results are presented for an investigation of ground antenna pointing errors which are caused by fluctuations of the receiver AGC signal due to thermal noise and a spinning spacecraft.

Adaptive antenna arrays for satellite communications: Design and testing [PDF]

open access: yes
When two separate antennas are used with each feedback loop to decorrelate noise, the antennas should be located such that the phase of the interfering signal in the two antennas is the same while the noise in them is uncorrelated.

Antenna Factorization in Strongly-Ordered Limits

open access: yes, 2005
When energies or angles of gluons emitted in a gauge-theory process are small and strongly ordered, the emission factorizes in a simple way to all orders in perturbation theory. I show how to unify the various strongly-ordered soft, mixed soft-collinear,

Limiting Characteristics for Receiving Small Size Frame Antenna Matching Using Converter Negative Impedance

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2018
The limiting characteristics of electrically small-sized loop antenna matching by means of non-Foster's negative inductance are studied. Various options for including negative inductance in frame antenna structure are considered.

Design and study of ultra-wideband folded loop antennas

open access: yesTongxin xuebao, 2010
Design of a novel ultra-wideband folded loop antenna was proposed.It was fed by coplanar waveguide and can be easily integrated with other microwave circuits.By introducing a pentagonal folded loop,the bandwidth of the an-tenna is improved twice than ...

Antenna subtraction with massive fermions at NNLO: Double real initial-final configurations

open access: yes, 2012
We derive the integrated forms of specific initial-final tree-level four-parton antenna functions involving a massless initial-state parton and a massive final-state fermion as hard radiators.
