“…In [6], a microstrip antenna based on the DGS and horizontal patch gap (HPG) was designed to satisfy bandwidth and higher performance criteria. [7] presents a compact wideband slotted hexagonal patch antenna for WiFi-5/6 communication with a modified ground structure. The reduced antenna size is significantly impacted by the redesigned ground plane structure.…”

This study aimed to develop a miniaturised rectangular microstrip patch antenna with a resonance frequency of 2.4 GHz. In order to achieve this, an initial microstrip antenna's resonance frequency was shifted from 3 GHz to a lower frequency by employing a defective ground structure (DGS) with a triangular-shaped slot into the ground plane. Also Triangular ring slots used defect the patch to improve co- and cross-polarization separation. Finally, a successful downsizing of up to 28% along the length and 18% along the width of the patch is achieved compared to the traditional 2.4 GHz microstrip antenna. The findings of the experiments have been obtained using high-frequency structure simulator software (HFSS). The substrate used in this work is RT/ Duroid 5880, which has a dielectric constant of 2.2 and a thickness of 1.575 mm.

“…For WiFi-5/6 wireless communication, a hexagonal slotted antenna is proposed by Paul LC. 20 It consists of a modified ground plane and an irregular hexagonal patch with two slots and achieved an impedance band of 5.1697-7.5388 GHz. Despite the attainment of 5.925-7.125 GHz band, some of the reported antenna characteristics are large volumetric size and complex footprint, and thus not suitable for handheld communication devices.…”

A semi-circular patch antenna (SCPA) is designed for WiMAX and WiFi-5/6 communications. The footprint of the proposed SCPA is only 30 Â 40 Â 1.575 mm 3 , which is composed of a semi-circular patch and a partial ground plane. The main strength of this work is that the estimated wide dual-frequency span of 2.39-3.75 GHz and 5.39-7.18 GHz are contributed with two sharp resonances at 2.77 and 6.46 GHz, respectively. The proposed SCPA has been practically tested after fabrication. The measured results confirm that the designed antenna achieved the bandwidth necessity for WiMAX 1.5(2.5-2.69 GHz), WiMAX 2 (3.4-3.6 GHz), and . In the two resonance frequencies of 2.77 and 6.46 GHz, the designed antenna achieved a gain of 2.558 and 4.109 dB, respectively. In addition, the SCPA also manifests good radiation properties and achieves an average efficiency of more than 90%. A professional version of the 3D electromagnetic simulator is utilized to examine the effect of diffident parameters and model the tested antenna.semi-circular patch antenna, partial ground plane, WiMAX, WiFi-5/6, CST | INTRODUCTIONWireless technologies are becoming progressive due to the dramatic increase in the demand for cellular internet connectivity to billions of wireless device users worldwide. 1 Different modern broadband wireless technologies like Bluetooth (2.4-2.485 GHz), LAN (5.47-5.725 GHz), WiMAX (3.4-3.6 GHz), mobile communication, radar, satellite communication and so forth use different frequency bands of the spectrum to meet the increasing demand of highspeed data transmission. [2][3][4] According to IEEE standard 802.11ac and 802.11ax, frequency band ranging from 5.925 to7.125 GHz is allocated to WiFi-5, and WiFi-6 is allowed to work at 5.925-7.125 GHz band. Recently, WiFi-6 (802.11ax) has been introduced, providing a peak data transfer speed of up to 9.6 Gb/s. 5 All wireless systems need a low-cost, simple and compact antenna to communicate effectively. 6 Due to low profile, lightweight and compactness features with higher efficiency, microstrip patch antennas have become very popular in current wireless devices. 7 A good number of antennas have already been reported to operate at the 5.925-7.125 GHz band. For example, for WiFi applications, Jianzhong and the rest 8 propose a dual-band miniature slot antenna. In the bottom layer of the designed antenna, there is a slotted radiator fed by an L-shaped microstrip line and resonating at 2.45 and 5.8 GHz. With an overall size of 20 Â 21 Â 1 mm 3 , the antenna achieved dual working bands of 2.42-2.49 GHz and
