Analysis of Extremely Low VSWR Characteristics of Feed Network of Rectangular Microstrip Patch Antenna
Journal Title: International Journal of Electronics Communication and Computer Technology - Year 2014, Vol 4, Issue 3
Abstract
This paper describes extremely low VSWR characteristics of coaxial and microstrip feed networks for slotloaded rectangular microstrip patch antennas. Both Inset feed and coaxial feed from the ground plane are considered to compare results for best impedance matching without much change in radiation pattern. It is found that by choosing feed structures and adjusting the slot dimensions and its number, resonance frequency can be adjusted to a desired value with very low VSWR characteristics. The design is optimized by modeling and simulation using Ansoft HFSS-13 software. Using low loss substrate of thickness 1.6mm having dielectric constant 2.2 design is made at 1.8 GHz which results in VSWR of as low as 1.01 and band width 1.8%.
