Enhance Bandwidth and Directive Gain in Rectangular Double Arrow Slotted Microstrip Antenna at 2 GHz

The design of a Broadband rectangular slotted microstrip antenna with circular polarization radiation. The antenna have the glass Epoxy substrate and single rectangular microstrip radiating patch, Rectangular antenna is designed for advanced technology, we first analyze the characteristics of microstrip antenna and design for the better efficiency, gain, and directivity, and design the microstrip antenna with EM simulator IE3D based on method of momentum The results show that the proposed antenna is able to achieve bandwidth of 42.85%, VSWR less than 2 and the return loss less then-10db.
