“…XLIM has worked for several years with the French Army (DGA) to carry out UWB pulse systems [4] [5]. Directive antennas have been realized during these studies like the Valentine antenna used for this experimental [1] [3] [6]. The UWB system allows to measure on a wide band, to have a real time measurement and to work without anechoic chamber.…”

A new patented project, which is called "Michelson project", is developed by XLIM (French research institute based at the University of Limoges) and the objective of this study is to measure a high electromagnetic field in a selected location. This system requires a simple equipement composed of a target, a receiving antenna, and a system of acquisition. The principle is the one after : the target is illuminated by the incident field which must be measured and diffracts this field in different directions and according to different polarizations. A receiving antenna is placed at a given place and recovers a part of the diffracted field at this location. The purpose is to come back to the incident field which lights up the target from the voltage measured on the receiving antenna output. To obtain the incident field, a global transfer function of this system must be calculated before. Moreover to be able to measure high electromagnetic field, this system has the advantage to disturb less the field in the zone of the measurement, if the dimensions of the target are small. According to the source and so according to the chosen receiving antenna, the Michelson project can measure as well harmonic signals as transient signals.

“…This sensor is not only used for the calibration, but also to measure directly the incident field and to compare the measurement with those obtained by Michelson system. The transmitting and receiving antennas used were Valentine antennas developed by IRCOM [3] [6]. Their bandwith is [0.3GHz-3.3GHz] and their maximum gain is 12dB.…”

XLIM (French research institute based at the University of Limoges) has just launched a new project which is called Michelson project and whose the concept has been patented. The objective is to measure an electromagnetic field in a selected location. This system is composed of a target, a receiving antenna, and a system of acquisition. The target is illuminated by the incident field which must be measured. This field is diffracted by this target in different directions and according to different polarizations. A receiving antenna is placed at a given place and recovers the diffracted field at this location. The purpose is to come back to the incident field which lights up the target from the voltage measured on the receiving antenna output. To obtain the incident field, a global transfer function of this system must be calculated before. One of many possible applications of this system is the measurement of high power which could be destructive for traditional receiving systems. Moreover this system doesn't disturb much the field in the zone of the measurement. The first tests validating this concept have been realized with transient pulse signals in Ultra Wide Band condition.

“…In design of these types of antennas, achieving good mechanical characteristics such as low thickness and area, beside wide bandwidth, are some well-known design goals for designers. In some papers several techniques adopting air substrate in circular patch antennas have been proposed to achieve a very wide bandwidth [1][2][3][4][5][6][7][8][9]. However the antenna thicknesses in these works are larger than 0.1 0 (where 0 is the wavelength in free space).…”

In this paper, a new probe-fed wideband antenna with a circular patch and a coupled stacked ring is proposed. This antenna can be implemented by using suspended microstrip technique with total thickness of about 0.09 of center frequency wavelength. By using a novel feeding technique, in this antenna about 40 % reduction in area compared to similar works can be achieved. The obtained bandwidth in this antenna according to simulation results satisfying VSWR<2 is about 27.5 % from 5 to 6.6 GHz using two resonant frequencies. Also a comprehensive theoretical and parametric study is done in order to facilitate its designing in various frequency bands.
