This paper discusses the permittivity measurement of different types of soil in Malaysia for Ground Penetrating Radar Application (GPR). Four different types of soil have been chosen as the samples which are wet sand, dry sand, wet clay and dry clay. The permittivity measurements of the samples are determined using Agilent Network Analyzer (E8362B) and Open ended coaxial probe method (Agilent Dielectric...
In this paper, the design of planar antenna for use in Ground Penetrating Radar (GPR) for buried object detection is presented. The proposed antenna offers wide operational bandwidth within 500 MHz to 2 GHz frequency band. This property makes the antenna suitable for the application of GPR for buried object detection. Taconic TLY-5 is used as the substrate with dielectric constant of 2.2, tangent...
In this paper, the design of wideband antenna with half and defected ground plane for buried object detection is presented. The antenna offers wide bandwidth from 0.5 GHz up to 3 GHz which is suitable for ground penetrating radar (GPR) system to detect buried objects under the ground surfaces. The simple structure and easy to integrate with planar substrate are the advantages of the antenna. A rectangular...
In this paper, a printed two C-shaped monopole antenna array for dual-band WLAN application is presented. The proposed antenna array contains two C-shaped monopole with a shorting line for connecting the two arms of the antenna elements. The purpose of the shorting line is to neutralize the current between the two arms which in return can increase the isolation. A parametric study was also carried...
In this work, a commonly used measurement techniques were used to define the reflection loss performance of pyramidal microwave absorbers mounted on a wall. The technique is namely, Radar Cross Section (RCS) measurement method. Six set of pyramidal microwave absorbers and flat square absorbers were installed at one side wall, in an RF shielded room in order to investigate the performance. Two types...
