“…2. A circular patch antenna's basic resonance frequency is determined by (1) Where, fr = resonant frequency of the patch X mn = 1.8411 for the dominant mode TM 11 C = velocity of the light in free space 𝜀r = relative permittivity of the substrate a e = effective radius of the circular patch and given by (2) In equation ( 2), 'a' is the actual radius of the circular patch antenna and h is the height of the substrate. By relating the areas of the circular and hexagonal radiating elements as stated in the equation given below, the aforementioned equations may be used to compute the side length s, of a hexagonal shaped microstrip patch antenna.…”

“…Building a multi-band antenna with a small footprint is not only necessary, but also challenging due to the limited space available for antennas in portable devices. Microstrip antennas are appropriate for portable wireless communication devices [1][2] due to benefits such as small weight, cheap cost, and simplicity of production. In contrast, a conventional microstrip antenna Volume 13, Number 7, 2022 has a single resonance frequency and a limited band width [3].…”

Microstrip patch antennas that are multiband and downsized are required to suit the high demand of modern wireless applications. To meet this need, a one-of-a-kind triple band array antenna has been proposed. The proposed 2x2 microstrip patch array, which comprises of four hexagon-shaped radiating patches are electromagnetically excited by a centrally positioned microstrip feed line in the same plane along with a slotted ground plane, is investigated. CST Microwave Studio, a powerful 3D electromagnetic analysis programme, was used to design and optimize the array antennas. The 2x2 array antenna was constructed on a FR-4 substrate with a dielectric constant of 4.3, a loss tangent of 0.001, and a height of 1.6mm. To optimize energy coupling from the feed line to the radiating patches, the ground plane has an H-shaped groove cut into it. The suggested 2x2 array antenna's multi- frequency behaviour is shown. Three resonant peaks were detected at 1.891GHz, 2.755GHz, and 3.052GHz. The observed bandwidths for these resonances are 234MHz, 69MHz, and 75MHz, respectively, with measured gains of 7.57dBi, 6.73dBi, and 5.76dBi. The goal of this work is to design, build, and test a single layer proximity fed array antenna. Standard proximity fed array antennas contain two substrate layers; however this array antenna has only one. As a consequence, the impedance matching and alignment are better. Simulated and experimental results showed that the this 2x2 array antenna operates in various important commercial bands, such as L and S bands and the array antenna might be beneficial for a wide range of wireless applications. The proposed antenna has good Impedance, S11, and radiation qualities at resonant frequencies. In this work, the 2x2 array antenna with hexagon-shaped radiating patches was successfully created utilizing the single layer proximity fed antenna concept and gap coupled parasitic patches.

“…Portable antennas are used to cover all of the following services and communication devices to cover numerous frequency bands simultaneously. The construction of a small-footprint multi-band antenna is not only essential but also demanding due to the narrow space available for antennas in handy devices [1,2]. Conventional non-planar antennas like horn, Yagi, disk, dipole, etc.…”

This article demonstrates the fabrication and measurements of a corporate offset-fed 2×2 array electromagnetically coupled patch (EMCP) circular antenna based on the Fabry-Perot cavity principle. A single-element antenna has a low gain of 6.28 dBi; it is enhanced to 13.45 dBi by loading the array with a superstrate. The antenna parameters—10 dB fractional bandwidth (FBW) and gain—are improved by an air gap with four stacked circular patches and four stubs in the proposed design. The peak gain of a 2×2 array without a superstrate was 8.88 dBi at 8.19 GHz, which was enhanced to 13.82 dBi at 9.55 GHz by parasitic loading and a superstrate. The FBW of the proposed array antenna was enhanced by arranging four stubs between the four circles in the superstrate structure. The − 10dB FBW without stubs was 24.82% (7.62–9.73 GHz), and with stubs it became 38.47% (7.73–11.0 GHz). Adjustment of the height of the substrate at 2.0 mm not only improves the gain and bandwidth but also supports enhancing the unidirectional radiation patterns. The array was prototyped and measured to validate the simulated reflection coefficients and radiation characteristics, which found excellent agreement with each other. Therefore, the designed array is most suitable for launchers in transitions, radio wave detection and ranging (RADAR), military, satellite, X-band communications, and microwave laboratory applications.

“…Machine learning algorithms can be used to create and optimize the radiation characteristics of the designed Sierpinski Carpet antenna (De Nicola et al, 2018). The reconfiguration of the antenna can be done by changing the antenna properties using different diode techniques (Masroor et al, 2021). The depth of the fractal structure depends on the number of iterations created in the antenna.…”

Multiband patch antenna has a very important part in the communication devices and systems. The benefits in designing and testing of Sierpinski carpet geometries for a low profile, cost effective multiband microstrip patch antenna for wireless standards is reviewed in this paper. The basic structure of the patch antenna is designed using the FR4 substrate with a thickness of 1.3 mm. The designed patch antenna structure is excited using the microstrip feed system. The Sierpinski carpet antenna structure is designed and simulated using High Frequency Structural Simulator (HFSS) software. The available Sierpinski carpet antenna structure in the literature is modified to make the preferred radiation patterns. The effects of the iterations of the modified Sierpinski carpet antenna structure over the generated return loss plots are discussed in this work. Based on the generated multiband behavior in the simulated results, the accomplishment of the designed antenna in the wireless domain was analyzed.
