Introduction

Ground Penetrating Radar (GPR) is a device that works by sending and receiving electromagnetic signals reflected into the ground. The GPR system is designed to detect the presence of objects buried in the soil at a certain depth. Generally, GPR operates at low frequencies to optimize the range of antennas. However, the dimensions of the antenna become very large. Therefore, this study designed a microstrip antenna with a small dimension without reducing the ability of antenna radiation range for GPR applications.

Ground Penetrating Radar (GPR) technology has been widely used in various fields such as archeology, geophysics, and civil engineering to detect and analyze objects buried in the soil. The GPR system consists of a transmitter and a receiver, which are connected to a control unit that processes the data obtained from the radar signals. The transmitter sends electromagnetic signals into the ground, and the receiver detects the reflected signals that are then processed to obtain information about the objects buried in the soil.

Design of Square Spiral Microstrip Antenna

The design of the square spiral microstrip antenna is carried out using an epoxy substrate FR4 with a thickness of 1.6 mm and permitivity (ER) 4.4. Square spiral microstrip antennas are characterized by changes in substrate dimensions, bait length, and patch antenna dimensions. The optimal dipole antenna simulation results get a return loss -30.64 dB and Voltage Standing Wave Ratio (VSWR) 1,061. The optimal design of the dipole microstrip antenna is then designed into a square spiral antenna without reducing the length of the dipole arm.

The design of the square spiral microstrip antenna is a crucial step in the development of GPR technology. The antenna is designed to operate at low frequencies, which is essential for GPR applications. The use of a square spiral design allows for a significant reduction in the dimensions of the antenna compared to conventional dipole antennas. This is very important for GPR applications that require portable devices and are easy to use in the field.
