Design of a Miniaturized Microstrip Antenna using Slots on the Radiating Patch for Wireless Applications

This paper proposed a miniaturized microstrip antenna (MMA). The design consists of a microstrip antenna having a radiating patch with modified U slots. Dielectric substrate of PTFE is used to design the antenna. Co-axial probe feeding technique is used to energise the MMA. HFSS software is used to model the design of the MMA. Initial patch antenna without slots, resonant at 6.65 GHz. After etching slots on the radiating patch, the MMA resonant at 3.85 GHz. So the 66.46% of miniaturization has been done. The MMA provides a maximum gain of about 5.54 dBi at 3.85 GHz. This design may be used to operate for wireless applications
