“…Defected Ground Structure (DGS) is a method reducing surface wave by partially etching the ground structure of an antenna [7]. The DGS is similar to the electromagnetic band gap (EBG) structure, but simpler [8]. Defected ground structure (DGS) can modify guided wave properties to provide a band-stop or band-pass like filter and can easily define the unit element [9].…”

Wireless technology is a wireless communication technology that is currently widely used by the public to exchange information. The current information exchange is growing as communication requirements rise. The antenna design needs to be improved in order to boost bandwidth. Microstrip antennas are one kind of antenna that can be used for wireless communication. Meanwhile, to improve the bandwidth value of the antenna can be done using the Defected ground structure or DGS technique. The results of testing the microstrip array circular patch antenna with DGS at 2462 MHz frequency show that it has a maximum gain of 15.7 dBi at a frequency of 2530 MHz and a return loss value of -19.3 dB with a VSWR value of 1,242. There is a type of directional radiation pattern in the antenna of the Microstrip Array with DGS. This study's findings indicate that the Circular Array Microstrip antenna with DGS has a bandwidth of 73 MHz while the Circular Microstrip Array without DGS has a lesser bandwidth of 28 MHz.

A compact extended bandwidth UWB microstrip antenna is designed utilizing metamaterial (MTM) doubleside planar periodic structures. The proposed antenna comprises two MTM unit cells made by etching X-shaped slots on the main radiating patch, and four slots at the vertices of a square periodically repeated in two-dimensions on the ground plane. The proposed antenna fabricated on 1.6 mm low-cost FR4 substrate is compact, measuring 27.6 × 32 mm 2 , with relative permittivity of 4.5 and loss tangent of 0.02. It has a broad bandwidth covering 3.2 to 23.9 GHz, with a peak gain of 6.2 dB at 8.7 GHz. The antenna has good radiation characteristics for UWB applications. The measured return loss (S 11 ) of the test antenna fabricated for this study was in good agreement with the simulated results. . Dr. Hamad has authored and co-authored over 40 technical peer reviewed papers in international journals and conference proceedings and he received 1 best paper award. His current research interests include the antenna design, MIMO antennas, mm-wave antennas, multiband/wideband small antennas for 4G/5G, metamaterials, UWB, and RFID. He is now designing microstrip antennas for 5G wireless communications using characteristics mode analysis.

“…The Defected Ground Structure (DGS) approach is a newly progressing technique for designing low profile antennas such as microstrip and dielectric resonator antennas. The DGS can be considered as Electromagnetic Band Gap (EBG) structure but easier [2], from which it developed. It shows a band-stop property and its area of application includes microstrip transmission lines and circuits.…”

Microwave engineers have been known to designedly created defects in the shape of carved out patterns on the ground plane of microstrip circuits and transmission lines for a long time, although their implementations to the antennas are comparatively new. The term Defected Ground Structure (DGS), precisely means a single or finite number of defects. At the beginning, DGS was employed underneath printed feed lines to suppress higher harmonics. Then DGS was directly integrated with antennas to improve the radiation characteristics, gain and to suppress mutual coupling between adjacent elements. Since then, the DGS techniques have been explored extensively and have led to many possible applications in the communication industry. The objective of this paper is to design and investigate microstrip patch antenna that operates at 2.4 GHz for Wireless Local Area Network WLAN IEEE 802.11b/g/n, ,Zigbee, Wireless HART, Bluetooth and several proprietary technologies that operate in the 2.4 GHz band. The design of the proposed antenna involves using partially Defected Ground Structure and circular/cross slots and compare it to the traditional microstrip patch antenna. The results show improvement in both the gain of 3.45 dB and the S11 response of -22.3 dB along with reduction in the overall dimensions of the antenna. As a conclusion, the performance of the antenna has been improved through the incorporation with the DGS and slots structures regarding the S11 response and the gain. The proposed antenna become more compact. Finally, the radiation pattern of proposed antenna has remained directional in spite of adding slots on the ground plane.
