[IEEE 2019 6th International Conference on Space Science and Communication (IconSpace) - Johor Bahru, Malaysia (2019.7.28-2019.7.30)] 2019 6th International Conference on Space Science and Communication (IconSpace) - Koch Fractal Loop Circular Polarization (CP) Antenna Integrated with Solar Cells
摘要： Minimal profile antennas for wireless devices which characteristics consisted of being low cost, highly reliable, and lightweight, it bears a new challenge for the design of the antenna in wireless communications. In this paper, we propose a design of circularly polarized microstrip patch antenna integration with solar cells for green wireless applications. Two techniques have been proposed to form the prototype between the communication system (design of antenna) and solar panel (solar cell). Both methods will face two issues generally; the solar system needs to get 100% sunlight and the magnetic field produced by radio communication systems as well as the electric field produced by solar cells should not affect the efficiency. The antenna is composed of a Koch fractal loop patch and the substrate is employed using a transparent material. This enables the light to pass through with high efficiency to illuminate the solar panel cells while the RF performance is maintained with minimal degradation. The communication frequency measures 2.6, 3.5 and 4.4 GHz. CST MWS simulation is also studied and compared among the different substrates which show different results based on the same parameters, which is implemented with a lattice of 2×2 square solar cells. With this arrangement, the solar cells will be able to obtain 100% of sunlight exposure. The characteristics of the broadband are achieved by combining resonances and the minimum axial ratio points created by the driven patch and solar cell surface.

Experimental investigation on Heat Distortion Temperature parameter of Polymer Matrix Composites for solar Panel Applications
摘要： In this paper the examination intended to create polymer matrix composites with polyester and vinyl ester better warmth opposition. The glass fiber with polyester favoured with various piece of composite with expansion of various fillers in various weight parts was created. Created utilizing vacuum sack shaping procedure. The mechanical properties were assessed utilizing Universal testing machine and the warmth mutilation temperature is the temperature at which a polymer or plastic example disfigures under a predetermined load. This property of a given plastic material is connected in numerous parts of mechanical assembly with various loads. Better mechanical properties and wear properties were gotten with increment in weight level of auxiliary fortification substance. The Heat Distortion Temperature is controlled by the test strategy delineated in ASTM D648.Further it was discovered that The extent 40:60 and 20:80 does not framed as flawless IPN consequently it is discovered that 80% vinyl ester and 20%poyurethane have great flexibility and sturdiness in correlation with different proportions.
