Analysis and design of broadband U-slot cut rectangular microstrip ...

The work started with basic rectangle antenna with resonant frequency 2. 43GHz and bandwidth of 68MHZ, then the same antenna was converted to U -slot patch antenna which resulted into lower shift in frequency of operation at 2. 10GHz.

respectively. By using the strip and slot, the proposed antenna deals properly with frequency shift for real application when embedded inside a handheld reader. V. CONCLUSION Thus the slot microstrip antenna was designed.The antenna shows good performance at 2.4GHz. Antenna gain, directivity, efficiency and return loss are measured. Microstrip Patch Antenna Designing at 2.4 GHz Frequency The figure-5 below shows the Voltage Standing Wave Ratio (VSWR) versus frequency graph of the designed antenna. The VSWR is minimum (equal to 1.1886031) at 2.4 GHz. In this paper a microstrip patch antenna is successfully designed at a resonant frequency of 2.4 GHz. The antenna shows a healthy gain if 8.27 dB.
