Abstract: The design and experimental demonstration of a Slotted Octagonal Patch MPA (Microstrip Patch Antenna) is presented which results in increases in Bandwidth from 3.95% to 12.5% at the range of 4.08GHz and the efficiency of 44.72 is also achieved. The geometry of slotted Octagonal MPA is designed on a FR4 substrate with a dielectric constant and tangent loss of 4.4 and 0.025 respectively.
