By using different fiber types as gain medium such as 500 m HNLF, 215 cm Bi-EDF, 7.2 km DCF, 11 km DCF, 18.2 km DCF, as well as the composition of Bi-EDF with 11 km DCF and finally the composition of Bi-EDF with the 18.2 km DCF, Raman gain was characterized and measured by the same set up as proposed in our study. The results revealed that the composition of Bi-EDF with the 18.2 km DCF provided the...
This paper introduces the performance of an elliptical shaped antenna with random slots with the use of parasitic element and compares the results between the original patch and the patch without dots stacked with parasitic element mounted on a high dielectric substrate. 5.8GHz is the reference or desired frequency set for measuring the performance of this antenna. The purpose of using parasitic element...
This paper introduces the performance of an elliptical shaped antenna with random slots with the use of parasitic element and compares the results between the original patch and the patch with parasitic element mounted on superstrate. 5.8 GHz is the reference or desired frequency set for measuring the performance of this antenna. The purpose of using parasitic element is to optimize the gain and radiation...

This paper introduces the performance of an elliptical shaped antenna with random slots with the use of superstrate and compares the results between the original patch and the patch with superstrate layer but without dots. 5.8GHz is the reference or desired frequency set for measuring the performance of this antenna. The purpose of using superstrate is to optimize the gain and radiation efficiency...

The 5850–7075MHz band is profoundly utilized for the fixed service such as Terrestrial Systems (TS) and microwave access (WiMAX) in various parts of the world. Nowadays, the High Altitude Platform System (HAPS) became a recognized system in this band. Therefore, terrestrial links are one of the most considerable interference with the HAPS gateway (HAPSGS) links. Hence, the legitimated interference...
In this letter, a circular polarized dielectric resonator antenna (DRA) using notched resonators excited through narrow slots is presented. To improve the gain, the slot positions were determined based on the characteristic of standing wave ratio over a short ended microstrip feeder. To enhance the bandwidth and circular polarization, three notched rectangular dielectric elements were rotated 45°...
