Design of rectangular microstrip patch antenna for improvement of Bandwidth : LAP Lambert Academic Publishing : 9786202816564 : 6202816562 : 30 Sep 2020 : Microstrip patch antenna is mostly used in modern communication devices over conventional antennas mainly because of their low cost, low profile, easy fabrication and due to its conformability. The objective of this book discusses about bandwidth improvement of Microstrip patch antenna using E-shaped and finally we got an improvement of 3.01% (70 MHz). The fabricated antenna has been done and the results have been seen by using Scale Network Analyzer (SNA). The bandwidth seen with the SNA is 3.03 % (73 MHz). A patch antenna is designed and simulated for 2.4GHz. the design patch antenna using substrate material FR-4, the shape used for conventional patch antenna is rectangular with insert feed, its dielectric constant is 4.4, dielectric loss tangent 0.0009 and thickness of 1.6mm.
