“…By introducing a delay (t 1 ) between the pulses feeding two adjacent sources the resulting electric field is steered at the azimuth θ 1 = 20 • . In this paper, the antenna used in the experiment of the autonomous scan is the Shark antenna, described in references [9,10]. It works over a very wide frequency band (higher than a decade) with a sectorial radiation pattern in the horizontal plane.…”

Abstract-A novel method allowing the ultrafast scanning of an area thanks to an Ultra Wide Band (UWB) antenna array is proposed in this paper. This method is based on the use of asynchronous optical pulses trains with different repetition rates obtained in amplified regenerative cavities. By means of optoelectronic switching, providing short powerful electrical pulses trains to an UWB antenna array, it is possible to spatially scan a large area in less than 1 ms. The paper presents the principle of the transient beam steering and its potentialities to realize an ultrafast detection system.

“…To radiate high‐power UWB pulse energy effectively, the antenna should achieve a wide bandwidth and high electrical capability to avoid a breakdown phenomenon, which leads to degradation of the radiation efficiency and damage to high‐power generators. In addition, to concentrate radiated high‐power energy for a target, directive radiation and low dispersion characteristics are recommended .…”

In this article, the design procedures and radiation characteristics of a compact high‐power antenna are discussed. The antenna is designed to efficiently radiate a high‐power ultrawideband nanosecond bipolar pulse. The fabricated antenna realizes directive radiation and a wide bandwidth of 0.2–3.44 GHz (17.2:1) with dimensions of 300 × 300 × 260 mm3 (width × height × length). The measured far‐voltage is 4.2 kV when the antenna is excited by a 2.5 kV amplitude bipolar pulse with a 1.3 nanosecond pulse width. © 2015 Wiley Periodicals, Inc.

“…Compared with the wavelength-scaled array concept, compact size can be achieved by selecting a UWB antenna element to compose the UWB antenna array. Among various UWB antennas [3][4][5][6][7][8][9][10][11][12], planar UWB monopole [6][7][8] and tapered slot antenna [9][10][11][12] are widely used in UWB antenna array designs, as they have characteristics of broad bandwidth, simple structure and easy fabrication.…”

Abstract-An integrated eight-element antenna array has been proposed for ultra-wideband (UWB) applications. It consists of eight UWB antenna elements and an eight-way binary-tree modified Wilkinson power divider. Any two adjacent elements in the array are connected to each other and share a common side, thus leading to a connected antenna array. Moreover, this arrangement can be utilized to avoid grating lobe level at higher frequencies. Each antenna element comprises a square ring patch and is excited by a tapered balun to achieve low cross-polarization levels. In order to validate the design, a prototype has been fabricated and measured. Both simulated and measured results confirm that the proposed integrated antenna array achieves a good performance of a reflection coefficient below −10 dB from 2.9 GHz to 10.8 GHz, including stable radiation patterns with low side lobe and cross-polarization levels, thus the antenna is promising for applications in UWB imaging systems.
