Spiral antennas and antenna arrays

2005 IEEE Antennas and Propagation Society International Symposium, 2005
The planar square-Archimedean spiral located at the center of a dipole has been demonstrated as a valuable passive antenna element in the upper MM-wave and THz regions between about 100 GHz and 2 THz (Bjarnason, E. et al., Appl. Phys. Lett., vol.85, p.3983, 2004).

Antenna design for a conformal antenna array demonstrator

2012 6th European Conference on Antennas and Propagation (EUCAP), 2012
Antenna arrays on aircrafts have several advantages if they will be integrated into the skin of the aircraft. However, conformal and structure integrated antennas are subject to aeordynamical loads which will cause vibrations and deformations of the antenna elements.

A Circular Fractal Antenna Array

2019 National Conference on Communications (NCC), 2019
In this paper, different arrays of the circular fractal antenna are analyzed. The various array design configurations are 1 $\times 2,1\times 4,2\times 2$ and $2\times 4$ . The substrate used is FR4 whose dimension is varied according to the array configurations.

Plasmonic nanoloop array antenna

Optics Letters, 2010
In this Letter, we create an optical nanoantenna array composed of parasitic plasmonic loops that can enhance radiation characteristics and direct the optical energy successfully. Three metallic loops inspired by the concept of the Yagi-Uda antenna are optimized around the region where they feature high scattering performance to control the radiation ...

Transient performance of array antennas

Proceedings of the IEEE, 1963
The transient performance of a uniformly excited, equal-spaced linear dipole array is evaluated under the assumption of constant radiated power over a finite frequency band. This approach permits the implicit evaluation of the effects of mutual coupling between array elements on transient performance.
