Three-antenna poststatistic steering using the MU radar
(American Geophysical Union, 1990-11)
This paper derives useful expressions for the synthesized beam statistics using poststatistic steenng (PSS), when three antennas are used in a spatial interferometer configuration for twodimensional steering. These antennas ...
Omnidirectional triple-band printed dipole antenna based on a dual frequency SRRs
(IEEEUSA, 2019)
This paper presents a compact triple-band planar antenna. The prototype is based on a printed dipole which is excited with Split Ring Resonators (SRRs) as resonant elements to get three frequency bands. To validate the ...
A new approach to nearly constant input impedance of self-complementary antennas
(Vsp Bv, 2020-07)
Conformal techniques, based on the covariance of Maxwell's electrodynamics under the full conformal group in four spacetime dimensions, are discussed in relation with the constant input impedance properties of frequency- ...
Woven Antennas Fabrication: Conductive Linen and Conductive Cloth Technologies Comparisons
(IEEE, 2018)
The development of woven antennas will enable novel applications in communications, sensing and safety, due to its inherent features such flexibility and textile-integration. For these reasons, this technology has attracted ...
Omnidirectional compact dual-band antenna based on dual-frequency unequal split ring resonators for WLAN and WiMAX applications
(Electromagnetics Academy, 2018)
An omnidirectional compact antenna based on dual-band Split Ring Resonators (SRRs) for 2.45 GHz wireless local area network (WLAN) and 3.5 GHz worldwide interoperability for microwave access (WiMAX) applications is presented. ...
Antenna compression using binary phase coding
(American Geophysical Union, 2001-01-01)
We introduce the first antenna “compression” scheme for coherent radars. The idea is to transmit with a large array of phase‐coded antennas at full power and later synthesize by linear superposition and proper phasing, the ...
Interpretation of angle-of-arrival measurements in the lower atmosphere using spaced antenna radar systems
(American Geophysical Union, 1998-05)
On the basis of scattering theory, we present four different contributions to angle-of-arrival (AOA) measurements using spaced antenna (SA) radar systems. We show that the measurement of the scattering parameters is needed ...
Design of high return loss logarithmic spiral antenna
(John Wiley & Sons Inc, 2017-10)
We propose a new strategy for designing a logarithmic spiral antenna and the impedance adapter to operate in a frequency range of 1 to 10 GHz. Numerical and experimental results show a decrease in return loss being higher ...
Directing Single-Molecule Emission with DNA Origami-Assembled Optical Antennas
(American Chemical Society, 2019-08)
We demonstrate the capability of DNA selfassembledoptical antennas to direct the emission of anindividual fluorophore, which is free to rotate. DNA origami isused to fabricate optical antennas composed of two colloidalgold ...
Wide axial-ratio bandwidth crossed dipole RFID antenna
(Elsevier Gmbh, Urban & Fischer Verlag, 2020-10)
A circularly polarised RFID tag antenna with wide axial ratio bandwidth, wide impedance bandwidth and simple tuning network is presented. The antenna, based on the widely used crossed-dipole design, incorporates a novel ...
