SHAFIQUE, Rabia et al. Comparison of different feeding techniques for a patch antenna at an X frequency band to evaluate its quantitative impact on the antenna’s parameters. J. appl. res. technol [online]. 2020, vol.18, n.6, pp.341-361.  Epub 30-Jul-2021. ISSN 2448-6736.  https://doi.org/10.22201/icat.24486736e.2020.18.6.1350.

In this paper, the comparison of different feeding techniques for a patch antenna, at X frequency band, to evaluate its quantitative impact on the different antenna parameters is presented. When different feeding techniques are applied at the X band spectrum to improve the impedance matching the performance of various characteristics parameters such as radiation pattern, gain, beam width etc are influenced. To find how much these are influenced a comparative analysis is carried out and results are presented in this paper. For investigation purpose, the patch antenna and the various feeding techniques were designed on Roger (RT5880) substrate at 8 GHz resonating frequency.
