“…The folded bowtie antenna is backed by copper reflector that offers 1 to 3 GHz bandwidth broadside gain of 5 to 12 dBi. Guo et al proposed a new antipodal tapered slot antenna (ATSA) of size 430 × 280 × 1.52 mm 3 with artificial material (AM) leans and reflector in the back area of antenna substrate that provides impedance band of 0.43 to 7 GHz and −3 dB gain band of 2 to 7 GHz 27 . Also UWB antipodal Vivaldi antenna of dimension 450 × 650 × 1.5 mm 3 with exponential tapered slots and slot edges is proposed in Reference 28 for air bone GPR system.…”

A simple structured single layered frequency selective surface (FSS) that has unit cell size of 11 × 11 mm2, substrate thickness of 0.8 mm only and capable to work in a very widespread band from 0.001 to more than 17 GHz is proposed in this article. The FSS is competent to augment the gain of a UWB monopole antenna by 2 to 3.5 dBi when integrated at the back of antenna. The performances of “antenna‐FSS” structure is evaluated by simulation and experimental measurement where good correlations are obtained. The integrated structure provides wide impedance band (S11 < −10 dB) from 2.82 to 19.94 GHz (more than 150%) with improved broadside radiation and high radiation efficiency profile. The transient and frequency domain characteristics of “antenna‐FSS” composite structure are also evaluated in close proximity of diverse sub‐surfaces such as dry sand, wet sand, wood and concrete where an almost unaltered impedance band profile, linear transfer function response and non‐varying group delay responses are achieved which establishes the applicability of the composite structure in ground penetrating radar for low depth sub‐surface scanning applications.

“…To survey the soil composition under the ground, the GPR needs to emit high-power pulses to the ground. To make the signal transmit deeper and to make its resolution higher, GPR's antennas are required to have a lower operating band, ultra-wideband and high gain [3]. GPR's antennas come in different types in different survey environments.…”

A novel compact Vivaldi Antenna (CVA) for short-pulse ground penetrating radar (GPR) systems is presented. Artificial materials lens (AML) and sidelobe suppressor (SSR) are loaded to improve GPR Antenna's radiation capability in the aperture and the flanks of the CVA. The simulation and experimental results indicate that the proposed CVA has a −10 dB impedance bandwidth of 100% (0.7-2.1 GHz) and a −3 dB gain bandwidth of 70.9% (1.0-2.1 GHz). Within the operating bandwidth of the CVA, AML primarily enhances the CVA's high-frequency gain (1.4-2.1GHz), while the SSR primarily enhances the CVA's lowfrequency gain (0.7-1.4 GHz). Moreover, the CVA loaded with two kinds of artificial materials (AMs) has an average gain of 1 dB and 2 dB in the low-frequency and high-frequency parts, respectively. In addition, the transmission response with small ringing in time domain makes the proposed CVA suitable for shortpulse GPR systems. AML and SSR effectively enhance the gain of the CVA with a compact and space-saving loading method, which provides a new idea to enhance the gain of the CVA by artificial material.

“…A tapered slot antenna (TSA) is one of the types of travelling wave antennas or planar end-fire antennas which have received considerable attention due to their wide impedance bandwidth characteristics. Vivaldi antennas have been used in numerous applications like satellite communications [2], Ultra-wideband (UWB) [3][4], scanning phased array [5][6], vehicular communication system [7], imaging construction material [8], medical imaging [9][10], cognitive radio [11], brain tumors [12], and GPR system [13][14]. The end-fire travelling wave antennas have demonstrated broadband bandwidth, high gain and symmetrically E -H beam pattern.…”

In this paper, a planar travelling wave tapered slot antenna with compact size is proposed for wireless communication applications. The prototype of antenna is developed on Roger RT/Duroid 5880 laminate with tan δ = 0.0009, a relative permittivity of 2.2 while working in the range of 6GHz-21GHz. The simple feeding technique transits with radial cavity and the opening taper profile. The antenna dimensions of the antenna have been designed in such a manner so as to enable impedance matching. The parametric study of the variables is carried out by various scrupulous simulations. The designed characteristic antenna has achieved an impedance bandwidth in the broadband spectrum of 111.11% at the minimum 10-dB return loss and peak realized gain of 7dBi is obtained for a resonant frequency of 19.6GHz. The simulated results are in good agreement with experimental results and hence make the antenna suitable for H (6-8 GHz), X (8-12 GHz), Ku (12-18 GHz) and K (18-26 GHz) and future wireless communication applications.
