“…Typical antenna design for ground penetrating radar (GPR) primarily focuses on optimising of antenna gain and impedance bandwidth [1,2]. For example, [3] uses a figure of merit based on gain, bandwidth, and size to compare various antennas for GPR. Gain and bandwidth requirements are focussed on because they relate to the most fundamental specifications given to a system designer: power, frequency, and link budget [4,5].…”

Currently, no publicly available comprehensive set of specifications exists for the design of ground‐penetrating radar antennas. Specifications are presented and derived for the design of a ground‐penetrating radar antenna based on the antenna's interaction with the rest of the radar system. Typically, ground‐penetrating radar antenna engineers are given basic parameters such as gain and bandwidth to design an antenna. An antenna can be designed to meet those specifications but may not perform well in a ground‐penetrating radar imaging system. By considering the whole system, including the operation parameters, expected targets, and signal processing algorithms, we can constrain the less‐commonly considered performance aspects of an antenna to perform more reliably in a deployment. We propose quantitative specifications for the antenna's coupling, beamwidth, boresight radar cross‐section, pulse integrity, residual ringing, and front‐to‐back ratio. Meeting these antenna specifications will decrease the probability that a deficiency in the antenna design impacts the radar's image output. Finally, a summarised design equation table that will be helpful in the ground‐penetrating radar antenna community at large is offered.

“…e contribution of patch antennas in different applications has been well acknowledged, thanks to their low cost, low profile, and simple fabrication process despite their relatively narrow bandwidth and low gain [1]. For instance, AlSabbagh et al reported a compact triple-band metamaterial-inspired antenna for wearable applications [2], Coburn and McCormick developed an ultra-wideband antenna for radar applications [3], Al-Janabi and Kayhan proposed a flexible Vivaldi antenna based on fractal design for harvesting the radio frequency (RF) energy in low-powered portable devices [4], and Naiemy et al designed, fabricated, and tested a monopole antenna based on electromagnetic band gap structure for GSM and WiMAX applications [5].…”

Improvement in the antenna gain is usually achieved at the expense of bandwidth and vice versa. This is where the realization of this enhancement can be made through compromising the antenna profile. In this work, we propose a new design of incorporating periodic metasurface array to enhance the bandwidth and gain while keeping the antenna to a low-profile scheme. The proposed antenna was simulated and fabricated in order to validate the results in the operating frequency range from 10 MHz to 43.5 GHz. Computer simulation technology (CST) microwave studio software was used to design and simulate the proposed antenna, while LPKF prototyping PCB machine was utilized to fabricate the antenna. Results showed that the antenna generated a gain and bandwidth of 14.2 dB and 2.13 GHz, respectively. Following the good agreement between the numerical and measurement results, it is believed that the proposed antenna can be potentially attractive for the application of satellite communications in Ku-band electromagnetic wave.
