Diamond Shape Microstrip Antenna using “Slots” at 2.5 Ghz, Antenna Efficient to Achive High Directive Gain

The Design of a Diamond shape slotted microstrip antenna with circular polarization radiation. The antenna have a 1.6 mm glass Epoxy substrate and single rectangular microstrip radiating patch, Where the radiating efficiency is high and also high Gain. The results show that the proposed antenna is able to achieve VSWR less than 2, antenna efficiency and radiation Efficiency above the 90% the percentage bandwidth is 25%.
