“…This feed provides a cut in the patch so that the feedline looks more protruding into the patch [3]. One of the ways to improve bandwidth in microstrip antenna is by using the DGS (Defected Ground Structure) technique [7] [8]. DGS is implemented by deforming the ground plane of the microstrip antenna by etching [9].…”

— Technological advances in the field of telecommunications without cables or wireless are growing rapidly by utilizing radio waves as transmission. This happens because people's mobility is currently quite high and requires practicality in the use of devices. The discussion in this paper is about the comparison of the design and fabrication performance of a diamond microstrip patch antenna composed of a 2x4 element array using DGS and without using DGS. The design was carried out using the CST 2018 simulator. The DGS was placed on a PCB ground plane with an epoxy fiberglass substrate having a dielectric constant of 4.58. This is measured by improving the value of VSWR, return loss, and bandwidth. The application of the working frequency used by the microstrip antenna is at (2401-2495) MHz for WIFI (Wireless Fidelity) networks. Microstrip antennas have a narrow bandwidth shortage, so they require bandwidth widening using the DGS (Defected Ground Structure) technique in the form of dumbbell square ahead. The resulting bandwidth is 15 MHz wider than a microstrip antenna without DGS. This research is in accordance with the antenna test parameters, which have a return loss value of -24.3dB, VSWR 1.12 and a bandwidth of 34 MHz.

This article concerns the design of a new quad-band monopole antenna with a specific configuration and reduced size. The antenna design is based on a single step meander-line parasitic structure, parasitic stubs, and double inverted L-shaped defected microstrip structure units on the top side of the substrate, and double rectangular-shaped defected ground structure units along with partial ground plane on the bottom side. This design procedure allows to achieve quad-band characteristics and improve the impedance matching. The fabricated antenna prototype with overall dimensions of (0.24λ0 × 0.17λ0 × 0.013λ0) is operating at 2.55, 3.65, 4.65, and 5.8 GHz with fractional bandwidth about 7.7, 12.84, 9.23, and 12.8%, respectively. The antenna exhibits an omnidirectional and a monopole like radiation patterns in the H- and E-planes, respectively, with suitable gains between 2.1 and 3.75 dBi. The measurement results are in good agreement with simulation values, which indicates that the proposed antenna design is suitable for WiMAX, LTE B7 (2.52–2.75 GHz), Sub-6 GHz 5G (n77) (3.39 – 3.87 GHz), Sub-6 GHz 5G (n78) (4.4–4.86 GHz), and WLAN, LTE B46 (5.1–5.82 GHz) wireless applications.

“…There are several applications for UWB technology, such as Ultra-wideband Pulse-Doppler radar, Automotive Radar, Ground Penetrating Radar, Precision geo-location, UAV data links, and many more. In the literature, several ways to expand the bandwidth were explored, such as the inclusion of slots on the radiating patch, on ground plane, on microstrip line, substrate truncation, printed and planar monopole antennas [2][3][4][5][6]. The cost and complexity of the antenna are greatly minimized with the use of CPW feeding method, as both the patch and ground are on the same side, a single layer copper clad is required instead of multi-layered copper clads [5][6][7][8][9].…”

A novel design of Ultra-Wideband (UWB) antenna with irregularly shaped hexagonal patch built on the elliptical-shaped FR-4 laminate with εr = 4.3 and tanδ = 0.025 is presented. The feed mechanism utilized in the structure proposed is modified co-planar waveguide (CPW), the feeding microstrip is tapered near the connecting edge of the patch for better impedance matching. The proposed antenna is compared with the traditional rectangular substrate and found that the elliptical substrate enhances the radiation characteristics of the antenna and is capable of functioning effectively in the range of 3.1 GHz-11.7 GHz, accompanied by the total efficiency > 86% across the whole FCC allocated UWB operating band. The antenna can be used for wide range of UWB applications as it exhibits good omnidirectional characteristics with a realized peak gain of 4.178dB and an average realized gain of 3.063dB. The simulation work of the antenna is accomplished using CST Studio (v. 2014).
