“…Since coaxial cable can be better matched to the microstrip line than parallel plate, the width of the lower strip is designed equivalent to 100 mm to act as a ground plate for the upper strip. In [10], the fields around a dipole placed in a lossless environment are studied. It is observed that the electric energy is greater than magnetic energy, which difference is called antenna reactive energy, calculated as below [10]:…”

In this paper, the design of an array of wideband combined antenna elements is presented. A TEM horn antenna is combined with magnetic dipoles to obtain a wideband element with a bandwidth from 180 MHz to 30 GHz. The element is then miniaturized in order to be placed in a two by two array, and then the optimized values of the horizontal and vertical spacings are calculated. To enhance the array bandwidth, a lens is placed in front of each element. This leads to an increase in the bandwidth from 0.2 to 10 GHz while no grating lobes appear over the bandwidth. The combined element is fabricated and the simulation results are verified by the measured data. Furthermore, simulation results for the return loss, radiation patterns and antenna gain for the 2 × 2 array are presented.

“…High peak power ultrashort electromagnetic pulse radios may help to make the technology a wider application. However, the peak power of the pulse output by one UWB/SP source is currently in limit, and using single source to generate high power ultrashort pulse is challenging [4,5]. A good solution is to use multiple relative low power pulse elements but with each output pulse of coherent phase, then radiate the pulses together to generate a high power pulse.…”

“…Research and development of the sources of ultra-wideband (UWB) electromagnetic pulses have been intensively conducted already for over 20 years (Baum & Farr, 1993;Koshelev et al, 1997;Agee et al, 1998). The main parameter characterizing the sources of UWB radiation is the effective potential (or figure-of-merit, Agee et al, 1998), defined as the product of the peak electric-field strength E p by the distance r in the far-field zone (rE p ).…”
