Optimization of the Feeding Point Location of Rectangular Microstrip Patch Antenna

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 1, Page # 382–386, 2020; DOI: 10.25046/aj050149
Abstract:

Microstrip patch antennas (MPAs) are comfortable and have better anticipation compared to traditional antennas. Not only the weight of this type of antennas is lighter but also, they have little capacity, minimum price, reduced in measurement as well as affluence of fiction then observance. Recently, it has been many times reevaluated for the improvement of…
