Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Circularly polarized dish parabolic antennas are highly valuable due to their superior resistance to external noise compared to linearly polarized antennas. Dish parabolic antennas equipped with end-fire helical feeds offer circular polarization, high directivity, and relatively low levels of side lobes. However, the presence of a conducting ground plane in the helical feed obstructs the reflected rays from the dish, resulting in a detrimental impact on the antenna’s directional characteristics. This research focuses on optimizing the ground plane through a series of FEKO simulations, leading to a significant reduction of side lobes and an overall enhancement of the antenna’s performance. Moreover, the introduction of knife – edge metallic scatters at specific positions and dimensions in the antenna configuration effectively decreases the sidelobe level within a range of 8 to 12 dB.
