This paper examines the role of a proper selection of a conducting material in the design of microstrip patch antenna. A microstrip patch antenna has three (3) main parts of ground, substrate and patch. The patch and the ground are made up of a conducting material. In this work, three (3) Rectangular Microstrip Patch Antennae (RMPA) were considered at 3.5 GHz resonant frequency for 5G applications with different conducting materials in order to determine the role of conducting material in designing a microstrip patch antenna. The antennae were designed, modelled and simulated using the same feeding methods, the same dimensions and the same materials with the exception of the conducting material. Copper annealed, iron and aluminium were used for the models of the antennae. It was found that the best conducting material was copper annealed, followed by aluminium then iron. Hence, the performance of a microstrip patch antenna depends on the type of conducting material used in its design among other factors. It is recommended that other conducting materials be explored to determine their role in ensuring effective design of the microstrip patch antenna.

A mathematical modelling, and a derivation of the main parameters of the Magneto – Dielectric materials (substrate) and their effect on microstrip patch antenna design is shown. The Magneto – Dielectric materials (substrate) is shown to miniaturize the antenna size and enhance the bandwidth when used in the design of the microstrip patch antenna. The progression of the foundational modelling starts with laying out the concepts of the ferrimagnetic materials in terms of their permeability and permittivity, the components of antenna miniaturization. First, a ground free elliptical microstrip patch antenna (GFDSEPA) is simulated for miniaturization purposes at the 900MHz cellular band. A size reduction of almost 50% as well as bandwidth enhancement (100%) is achieved by utilizing the GFDSEPA. More size reduction is achieved by employing the magneto – dielectric structure; in this case the commercially available Rogers MAGTREX 555 substrate is used. Other performance parameters show comparable results between the antenna simulated based on dielectric only substrate and the one based on magneto–dielectric substrate. A comparison of the main parameters between the results of this work and other results in the literature is shown. The application of the microstrip patch antenna design in energy harvesting, by using a rectifier circuit, is shown. Layout scenarios of the energy harvester are proposed. The proposed layout of the energy harvester ensures practicality of the proposed design and assures correlation between simulation results and experimental results.

This paper presents comparison of rectangular micro strip patch antenna and E-Shaped micro strip patch antenna operating at 2.45GHz. Two parallel slots are made into the basic rectangular patch design of micro strip antenna which resulted into desired E-shaped patch.

&lt;p&gt;An antenna may be thought of as a temporary tool that directs radio waves for transmission or reception. Aside from being inexpensive, small, easy to manufacture, and compatible with integrated electronics, the microstrip patch antenna (MPA) offers several other benefits as well. These two methods are often seen as low-cost, adaptable, dependable, high-speed data connection choices that promote user mobility. An overview of how MPA have been used throughout the last several decades is provided in this article. It has been suggested that there are many approaches to enhance the performance of MPA, including the use of composite antennas, highly integrated antenna/array and feeding networks, operating at relatively high frequencies, and using cutting-edge manufacturing methods.

The use of unmanned aerial vehicle (UAV) has been increasing rapidly in the civilian and military applications, because of UAV's high-performance communication with ground clients, especially for its intrinsic properties such as adaptive altitude, mobility, and flexibility. UAV deployment can be monitored and controlled through 5G wireless network as user equipment (UE) along with other devices. A highly directive microstrip patch antenna (MPA) could establish long-distance communication by overcoming air attenuation and reduce co-channel interference in the limited region if UAV uses a specifically dedicated band, which might enhance spatially reuse of the spectrum. Also, MPA is highly recommended for UAV because of its low weight, low cost, compact size, and flat shape. In this paper, we have designed a highly directive single-band 2×2 and 4×4 antenna array for 5.8 GHz and 28 GHz frequency respectively for UAV application in a focus to deploy UAV through 5G wireless network.

Design and analysis of novel microstrip patch antenna on photonic crystal in THz

Textile-based antennas are of great importance for wearable devices due to their flexible and compact design, which allows the creation of efficient wearable technologies. However, the use of flexible substrates in wearable antennas presents a number of challenges, including frequency shifts that occur during bending. A comprehensive analysis of the bending characteristics of flexible substrates is absent from the existing literature. The objective of this study is to analyze the performance of a Wi-Fi Microstrip Patch Antenna (MPA) designed to operate at 2.4 GHz using flexible substrates, such as leather, fleece, and felt, with a detailed examination of their bending characteristics. A bending analysis was conducted to measure the impact on performance metrics, such as return loss, bandwidth, gain, and Voltage Standing Wave Ratio (VSWR) under bending angles from 0° to 17°. The leather substrate exhibited minimal degradation in performance. The antenna demonstrated a return loss below -15 dB, a bandwidth exceeding 4%, a gain exceeding 5 dB, and a VSWR lower than 2.5 across all tested conditions. The leather substrate has emerged as a promising candidate for wearable Wi-Fi applications due to its ability to maintain stable performance metrics under bending conditions.
