“…Bowtie antennas are suitable for GPR applications because it fulfils ultrawide-bandwidth specifications [6]. Broadening the antenna bandwidth can be done by various methods, which are uses defected ground structure [7], fractal antenna method [8]and self-complementary. In research [9]comparing the design of a bowtie planar antenna without and with the self-complementary method for UWB applications, the comparison results show that the bowtie antenna with a self-complementary antenna has a simple design and does not require complex matching to get wide-bandwidth and detail bandwidth obtained was 8.75 GHz.…”

Ground Penetrating Radar (GPR) is a method facilitating effective detection of buried object underground surface by utilizing the ultrawideb and (UWB) electromagnetic wave without damaging the soil structure. Antenna is an important part of GPR System. In order to obtain its best performance, an antenna must fulfil the UWB characteristic and has a low ringing level. One type of the antennas which is best applied to GPR application is bowtie antenna. The bowtie antenna with a self-complementary design aimed to get ultrawide bandwidth, on the other hand the antenna also produces relatively large ringing level. To cope with this matter, a resistive loading is performed to minimize the large ringing level. The research involves designing the antenna according to the required specification. A simulation is conducted to investigate the characteristic of the proposed antenna and to obtain the design that fulfil the intended specification and is followed by realization of self-complementary bowtie antenna with resistive loaded. The antenna is realized using a dielectric substrate FR-4 with a relative permittivity value of 4.3 and the thickness of 1.6 mm. The designed antenna produces a bandwidth 1300 to 2200 MHz and ringing level value which are less than -30 dB.

Ground Penetrating Radar (GPR) is a radar used to detect an object located/buried under the ground surface at a certain level of depth using electromagnetic radiation in the microwave band, without causing damage (non-destructive) on the surface. According to the function of the filter which can do frequency selection on a system, the need for a filter connected on the block next to the antenna in a GPR circuit is necessary. This filter helps the system to check and select the transmitted frequency and received frequency from the antenna. In this paper, microstrip structure is applied in filter design to obtain ultra-wideband (UWB) characteristic and to provide compact shape. The design of a two-patch case composite bandpass filter is proposed to fulfill the requirement. The design utilizes a combination of a stepped-impedance lowpass filter (LPF) as the upper stopband and quarter-wave highpass filter (HPF) to realize the lower stopband. A simulation is conducted on a dielectric substrate having a 4.4 dielectric constant and 1.6 mm thickness, followed by realization. The realization results show that the proposed filter have a good performance and produce 980 MHz wideband bandpass filter from 1.394-2.371 GHz with center frequency at 1.873 GHz. The filter has return loss value less than -10 dB and the filter rejection is sharp.
