“…For frequencies above 5GHz, the agreement was not as good, but the measured S 11 adequately satisfied S 11 d-10dB. It is noted that [9] had problems with simulated and measured agreement at higher UWB frequencies. Design 3 gave 138% fractional bandwidth across 2 to 11GHz, exceeding the 120% requirement.…”

“…As linear polarization is required, the higher gain UWB travelling wave antennas based on flared structures originally developed in the 1940s [6][7][8] are candidates for this system: TEM horn, Libellule antenna, Valentine antenna, Impulse Radiating antenna (IRA), and Vivaldi antenna [9,10]. The Vivaldi antenna is readily manufactured by PCB process, and is taken as a baseline antenna design in this work.…”

A planar Vivaldi antenna was reconstructed and assessed as a candidate for a short range, high range resolution railway cutting monitoring radar. The initial flare section of the Vivaldi antenna was found to control the return loss of this type of antenna at lower frequencies, and a compact antenna for 120% fractional bandwidth was demonstrated experimentally. Group delay was used as a UWB antenna assessment method, and the prototype antenna gave reasonable performance across the lower half of the band considered.

“…Then, a Koshelev-like ultra wide band antenna [28] radiated this transient electromagnetic signal in the form of repetitive pulses (100 Hz pulse repetition frequency). This compact antenna (38.5 × 30 × 30 cm 3 ) has been designed and optimized by CISTEME [29] to widen the bandwidth from 200 MHz to 2 GHz. The biological samples were located in the antenna heart between the two radiating elements (Figure 1(b)).…”

Ultrawideband electromagnetic pulses with high amplitude and short duration are reported to affect several aspects of cell physiology. They are usually delivered to the living material through electrodes in small dedicated chambers. Here we showed, using a totally different experimental setup, that radiated EM pulses illuminating the living material through a specialized antenna (without any direct contact) are able to trigger a rapid release of ATP in cultured murine cells that was concomitant with a drop of intracellular AEC. Despite this rapid and strong response, we found that cell viability and clonogenicity were only slightly affected by the EMF exposure.

“…In addition to the telecommunications, UWB antennas are widely used for a variety of civil, space, biomedical, and military applications [ 3 , 4 , 5 , 6 , 7 ]. They can include UWB pulse radars to detect buried mines or to rescue buried people, as well as the generation of electromagnetic pulse for electromagnetic compatibility and vulnerability tests on electronic and IT equipment [ 8 ]. Moreover, during the last few years, they have been implemented in a wide range of military systems requiring spectrum-agility or multifunctionality, such as direction finding systems, electromagnetic jamming, passive radar seekers, antiradiation missiles, and radar electronic support measures [ 9 , 10 , 11 , 12 ].…”

In this paper, the recent progress on sinuous antennas is detailed, focusing the attention on the antenna geometry, dielectric structure, and miniaturization techniques. In the first part, we introduce the basic principles of the frequency-independent antenna, in particular the self-complementary and log-periodic geometries, as well as the antenna geometries, all characterized in terms of angles. The operating principles, main advantages, system design considerations, limits, and challenges of conventional sinuous antennas are illustrated. Second, we describe some technical solutions aimed to ensure the optimal trade-off between antenna size and radiation behavior. To this aim, some special modification of the antenna geometry based on the meandering as well as on the loading with dielectric structures are presented. Moreover, the cavity backing technique is explained in detail as a method to achieve unidirectional radiation. Third, we present a new class of supershaped sinuous antenna based on a suitable merge of the 2D superformula and the sinuous curve. The effect of the free parameters change on the antenna arm geometry as well as the performance improvement in terms of directivity, beam stability, beam angle, gain, and radiating efficiency are highlighted.
