“…Considering that rectangular patch antennas are widely used over other structures [43][44][45], the proposed antenna is based on a rectangular patch slotted with two identical hammer slots and a single rectangular slot placed between them. The substrate used was a Rogers RT5880 having the following dimensions: 20 mm length, 16.5 mm width, and 0.508 mm thickness.…”

Microstrip patch antennas have been widely used in contemporary mobile communication technology, including 5G. Previous studies in the area have shown that such antennas can be optimized to operate in different bands of 5G. This study proposes a microstrip patch antenna designed to operate at 26 and 28 GHz and aimed at improving the gain and other radiation characteristics by adding a combination of different slot shapes to a single rectangular patch that is very common and popular in 5G antennas. The results show that the gain is noticeably increased by inserting two hammer slots and a rectangular slot in the middle between them. The dimensions of the slots are optimized using the CST Studio Suite simulator. A comparative analysis was performed to demonstrate the superiority of the proposed over previous designs in terms of gain value and other radiation parameters. The results suggest that such a very simple and low-profile antenna can be a good candidate for 5G mobile applications.

“…It was able to achieve an efficiency of 0.02129 dB with a bandwidth of 3161 MHz. By incorporating various configurations (rectangular and U) of single and double slots into the patch, as well as inset feed and coaxial feed methods, a basic rectangular patch antenna was developed to boost bandwidth and efficiency (Nahas 2019).…”

The demand of small, lightweight and high effectiveness antennas has increased significantly with the development of communication technologies. Microstrip patch antennas (MPAs) are one of the most widely used types of antenna that can satisfy these requirements. MPAs have numerous benefits, including tiny size and weight, ease of fabrication, and inexpensive. In addition to these advantages, MPAs also have some drawbacks such as limited bandwidth and low efficiency. In this paper, a compact rectangular patch microstrip antenna employing hybrid technique (HT) is designed to enhance the bandwidth and efficiency and its performance is compared with that of a conventional antenna. The HT is formed by combining a slotted patch with a defected partial ground structure. A low-cost FR-4_epoxy substrate material with a dielectric constant of 4.4, a thickness of 0.8 mm and a loss tangent of 0.02 is used to make both antennas designed. The antennas are designed, analyzed and simulated at the operating frequency of 6.85 GHz for ultra-wideband (UWB) (3.1-10.6GHz) applications using high-frequency structure simulator (HFSS) software. The overall size of the proposed antenna is 30 mm × 20 mm × 0.8 mm. A 50 Ω microstrip feedline is used to excite the patch. The outcomes of the simulation reveal that the suggested and conventional antennas achieved a bandwidth of 19.7 GHz and 2.53 GHz with an efficiency of 95.779% and 92.296% respectively. The recommended antenna has boosted in bandwidth and efficiency by 17.17 GHz (137.24%) and 3.483% respectively as compared to the traditional antenna.

“…Corner truncation also ensures the circular polarization of the antenna. Figure 1 The microstrip antenna dimensions are based on standard mathematical models inspired by the literature for the design of the MPA [15][16]. In order to analyze the performance of the antenna, certain parameters need to be taken into account, such as the return loss S11, gain, and directivity.…”

This paper presents a Circularly Polarized Microstrip Patch Antenna (CPMPA) miniaturization with parasitic elements, suitable for UHF RFID systems. The antenna consists of a half E-shaped patch with cuts. A truncated corner patch can generate an additional Circular Polarization (CP) radiation mode and further enhance the axial ratio. Two symmetric cross shaped slots along the horizontal axis of the CPMPA have been embedded, and its dimension optimization has been based on parametric analysis. Thanks to this slotted structure and reduced surface area, good CP quality has been obtained with a 25% overall size reduction. The proposed antenna is lightweight, low profile, simple, and easily produced. The structure’s simulation is made using CST Studio Suite 2014 to compute return loss (S11), gain, and the axial ratio of the antenna while the overall miniaturized antenna’s volume is 77mm×58mm×1.6mm operating at 915MHz.
