COMPARISON

COMPARISON BETWEEN CIRCULAR AND RECTANGULAR DESIGN OF YAGI PATCH ANTENNA
Following table2 gives comparison of results of Rectangular and Circular patch antenna:

t003.jpg

From simulation result of circular and rectangular yagi patch antenna it is clear that the performance parameter changes as change in geometry.

 

COMPARISON OF SIMULATION ON DIFFERENT SOFTWARE

Following table gives comparison of result on different software:

t004.jpg

From above table it is clear that performance of antenna parameter vary with simulation software .HFSS gives the improved results.

CONCLUSION
In previous work same antenna was designed in CST MICROWAVE studio software but the result were not satisfactory. Same design in HFSS gives improved result. With this design we get improved result of return loss ,F/B ratio, but gain result is not satisfactory. Gain can be improved by changing some dimension.
For  wifi antenna is the best solution previous work has done with CST software , but some antenna is proposed with HFSS software which has given the improved result and lower F/B ratio. Dielectric constant used for this antenna is FR4 epoxy which is easily available in market. By changing the shape, dimension the simulation will be performed and the result will be taken and with best result antenna will be fabricated.
