In this work, we present a miniature multi-layered patch antenna for K-band applications. The size of the antenna has been optimized by using two substrates layers, introducing a rectangular probe between the layers, and insertion of an air-filled cavity into the lower substrate. Analysis and modeling were performed using the HFSS (High Frequency Structure Simulator) simulator based on the finite...
In this paper, we will analyze the received signals (A-scan profile) of a 2D Simulation with the FDTD method of GPR modeling applied to the detection of water presence in an underground cavity for a ground covered with a layer of clay. It's an application used generally in the supervision of civil engineering works before the construction of buildings. For our study, we chose a homogeneous soil covered...
The main objective of this work is to make a comparative study of the radiation patterns of circular patch antenna excited in transverses magnetics modes TM11, TM21, TM31, TM41, TM51 and TM61. This antenna is printed on a Epoxy substrate having a dielectric constant of 4.4 and designed at a height 1.58mm from the ground plane. This study is based on the model approach of the resonant cavity and intended...
