This paper reviews the objectives and requirements of wideband antenna for millimeter-wave applications using HFSS software (Ansys HFSS V.15.0). In modern era, all wireless devices are multipurpose and versatile, so this requires a wideband antenna to perform different tasks. Microstrip patch antennas are enhancing the performance of communication systems. Patch antennas are becoming more common these days because to their low profile and small weight, making them simple to build. The antenna and propagation issues are further complicated by need for more power, wider bandwidth, stronger gain, and insensitivity to the presence of human users. To provide dependable and interference-free communications and for high-performance millimeter-wave devices need efficient low-profile antennas.

Рассматриваются методы проектирования для расширенной интеграции низкопрофильных антенн с солнечными системами для беспроводной связи малого радиуса действия. Необходимость перехода к более устойчивым источникам энергии возникает из-за чрезмерного производства вредных выбросов углерода. Основное внимание уделяется способам интеграции антенн и солнечных панелей из кристаллического кремния. Было предложено решение для минимизации чувствительности, которое использовалось для успешной изоляции микрополосковой линии передачи от солнечной решетки, что позволило продемонстрировать пять конфигураций антенн. Дальнейшая работа над кристаллическими солнечными панелями продемонстрировала их использование вместе с антеннами с круговой поляризацией для летательных аппаратов, а также позволила показать необходимость их использования совместно с Mesh-антеннами для небольших спутников. Солнечная дипольная антенна была разработана для использования внутри помещений с низким энергопотреблением. Эти подходы позволили создать инженерные возможности для уменьшения размера и веса устройства за счет интеграции технологий радио- и солнечных панелей. Представлены основные характеристики антенн для исследуемых случаев, произведено их сравнение, а также определено влияние на их параметры проводниковых материалов The article considers methods for advanced integration of low-profile antennas with solar systems for short-range wireless communications. The need to move to more sustainable energy sources arises from the excessive production of harmful carbon emissions. The focus is on the ways to integrate crystalline silicon antennas and solar panels. We proposed and used a solution to minimize sensitivity to successfully isolate the microstrip transmission line from the solar array, thus demonstrating five antenna configurations. Further work on crystalline solar panels demonstrated their use in conjunction with circularly polarized antennas for aircraft and it also allowed us to show the need for their use with Meshed Patch Antennas for small satellites. A solar dipole antenna was developed for low power indoor applications. These approaches created the engineering capability to reduce device size and weight by integrating radio and solar panel technologies. The article presents the main characteristics of antennas for the cases under study, compares them, and determines the effect of conductive material on their parameters

While the revolution in antenna engineering leads to the fast-growing communication systems, Microstrip Patch Antennas (MPA) have proven to be the most unconventional discovery in the epoch of miniaturization. This paper incorporates the designing, simulation, and analysis of rectangular & circular microstrip patch antennas. The resonating frequency of the proposed patch antennas is 9 GHz, lying in the X band region and are designed on Rogers RT/duroid 5880 material having dielectric constant 2.2, using Ansys HFSS software. The proposed MPAs were compared on the basis of five performance parameters (Return loss, Bandwidth, VSWR, Gain and HPBW). It was observed that rectangular MPA has a higher value of return loss, VSWR and HPBW than circular MPA. Whereas, circular MPA has greater bandwidth and gain than rectangular MPA. The proposed antennas can be used in radar, wireless and satellite applications.

Antenna is a very important element and plays a key role in communication systems for radiating energy. Based on high data rate speed requirements and large volume multimedia applications, 3G, 4G and now 5G technologies have been introduced and implemented. This paper presents a low profile antenna with novel structure and large continuous bandwidth for 5G broadband and millimeter-wave wireless applications. It is an H-plane printed horn antenna with multi-layered sandwich substrate. There are two Rogers (RO3003(tm)) substrates that make a sandwich structure with eight stainless steel columns. The proposed antenna is expected to give an impedance bandwidth 20-45 GHz with S11 <-10dB and 8.64dBi gain at 28 GHz design frequency. ANSYS 18.2 HFSS simulator is used for designing and optimization of the profile antenna. A comparison between simulated and measured results confirms the validity of the proposed design.

The modern era belongs to wireless communication systems. The cellular networks, which were originally designed for voice services, have now been upgraded to accommodate Internet services. Wi-Fi and Wi-Max systems have been explicitly developed for delivering data services over wireless channels. Just like wired systems, wireless systems also follow the layered architecture for developing or accessing various Internet services; still, there exist significant differences between the technologies used at various layers for the similar purpose. Special design requirements of physical layer due to distinct properties of wireless channel have caused these differences. Low bandwidth supported by the channel, poor equipment capabilities, et cetera, features require special attention in developing various Internet services intended to be accessed by wireless devices. This chapter addresses various aspects of the physical layer of a wireless channel for developing a basic understanding of the problems, existing solutions, and proposals for future networks.
