2006 (English)In: Journal Electromagnetic Waves and Applications, ISSN 0920-5071, E-ISSN 1569-3937, Vol. 20, no 2, 227-236 p.Article in journal (Refereed) Published
This paper presents an analysis of planar parabolic shaped dipoles using the finite difference time domain (FDTD) method. The antenna is resistor-loaded to improve the bandwidth and shielded to suit ground penetrating radar (GPR) applications. The clutter level and the GPR response of the antenna when it is operating above both lossless and lossy mediums are analyzed. The input impedance and the radiation characteristics of the antenna are also described. The results are compared with those of the resistor-loaded bow-tie to assess the antenna's performance.
