Design and Analysis of Substrate Reliant Slotted Microstrip Patch Antenna for Modern Communication

A novel slotted microstrip patch antenna (MSA) is designed using FR4 epoxy dielectric substrate with coaxial feeing. A comparative analysis of slotted antennas with coaxial feeding is performed using various dielectric substrates, and the same antenna is then designed by modifying the coaxial feed’s co-ordinates to validate the influence on antenna performance. At the desired frequency, it can be demonstrated that FR4 epoxy offers the suitable impedance matching and bandwidth. The operational frequency response(s) of the antenna are 6, 8.2, 10, and 12 GHz, and the dielectric substrate material used in construction is FR4 epoxy. The maximum reflection coefficient obtained is −19.9 dB at 5.9 GHz resonating frequency and achieved gain of 5.5 dBi. The antenna is intended for use in wireless communication systems.
