A simple analysis of dipole antenna radiation above a multilayered medium

Characterization of Antenna Radiation Pattern and Penetration Depth in Ground Penetrating Radar Field Missions

“…Finally, Figure 5 highlights the complexity and ambiguity of the term "pulsed GPR radiation pattern", cf. [13][14][15][16][17]. These analytical results are presented here in order to provide a rough qualitative picture of realistic GPR radiation characteristics and illustrate the problem of their quantitative estimates.…”

“…All of them have antennas made as dipoles of different lengths, with the resistive loading roughly following Wu-King's law [12] and minimizing "ringing" at the antenna's central frequency. Although the radiating and receiving properties of GPR antennas have been studied in a number of theoretical and experimental works (see [13][14][15][16][17][18][19][20]), georadar missions provide a good opportunity to assess their performance under realistic operating conditions.…”

Characterization of antenna radiation pattern and penetration depth in GPR field tests

“…First of all, we were interested in estimating the radiation pattern of the resistively-loaded dipole antennas used in this enhanced power georadar. Although this important parameter has been studied in a number ot theoretical and experimental works [6][7][8][9][10][11][12], full-scale field measurements are invaluable for geophysical and industrial applications.…”

Simple analytical models for the calculation of the electric field radiated by the base station antenna

“…Four different models for the assessment of the field radiated by the base station antenna are presented; the antenna insulated in Free Space (FS), the antenna above Perfect Ground (PG) and the antenna above a lossy half space. The half-space model uses the reflection coefficient stemming from the Snell's law and Fresnel's equation [7][8] but also from the MIT approximation [9][10]. The paper is organized as follows: Mathematical Model is presented in Section II, and it is followed by a number of illustrative computational results.…”
