OVERVIEW OF METHODS TO INTEGRATE ANTENNAS AND SOLAR CELLS

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

Modern Era

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.

In this paper, a low-profile HF (high-frequency) meandered dipole antenna with a ferrite-loaded artificial magnetic conductor (AMC) is proposed. To operate in the HF band while retaining a compact size, ferrite with high permeability is applied to the unit cell of the AMC. The operating frequency bandwidth of the designed unit cell of the AMC is 1.89:1 (19–36 MHz). Thereafter, a meandered dipole antenna is designed by implementing a binary genetic algorithm and is combined with the AMC. The overall size of the designed antenna is 0.06×0.06×0.002 λ3 at the lowest operating frequency. The proposed dipole antenna with a ferrite-loaded AMC is fabricated and measured. The measured VSWR bandwidth (<3) covers 20–30 MHz on the HF band. To confirm the performance of the antenna, a reference monopole antenna which operates on the HF band was selected, and the measured receiving power is compared with the result of the proposed antenna with the AMC.

Solar Field

A real case study of an energy system based on a Solar Assisted Heat Pump (SAHP) fed by hybrid photovoltaic-thermal solar panels (PVT) and seasonal storage (SS) is presented in this paper. Exergy and exergy cost analyses are proposed as complementary methods for the assessment and better understanding of the efficiency of this cogeneration solar configuration. The system performance takes advantage of storage heat in summer, when the solar resource is high in Spain, and is then later consumed during the cold winter (heating season). The building is devoted to social housing, and it is currently under construction. The assessment is based on simulations developed using TRNSYS, a dynamic simulation software for energy systems. Results show that the unit exergy cost of the solar field is around 6. The cost of the seasonal storage is higher, about 13, and its formation is affected both by its own irreversibility and by the irreversibility of the PVT solar field. The cost of the heat delivered by the heat pump is around 15, being affected by all the upstream units and even by the grid. Besides, the analysis points out strategies for improving the system efficiency, such as increasing the size of the storage tank or improving the control strategy of the boiler.

The Cost

As small satellites are becoming more widespread for new businesses and applications, the development time, failure rate and cost of the spacecraft must be reduced. One of the systems with the highest cost and the most frequent failure in the satellite is the Electrical Power System (EPS). One approach to achieve rapid development times while reducing the cost and failure rate is using scalable modules. We propose a solar module integrated converter (SMIC) and its verification process as a key component for power generation in EPS. SMIC integrates the solar array, its regulators and the telemetry acquisition unit. This paper details the design and verification process of the SMIC and presents the in-orbit results of 12 SMICs used in Ten-Koh satellite, which was developed in less than 1.5 years. The in-orbit data received since the launch reveal that solar module withstands not only the launching environment of H-IIA rocket but also more than 1500 orbits in LEO. The modular approach allowed the design, implementation and qualification of only one module, followed by manufacturing and integration of 12 subsequent flight units. The approach with the solar module can be followed in other components of the EPS such as battery and power regulators.
