dear in which type help you need

Dear Khan,

According to you application, you have to define the radiation pattern (or the characteristics) of your antenna. For example, in WSN, you will have better performance when you define the antennas to be omnidirectional antenna. Additionally, omnidirectional antennas will let your system suffer if several nodes are colocated near each others. In other words, whether you need to apply overlapping or nonoveralapping clustering schemes?!

Using HFSS tool for making omnidirectional antennas for RFID or WSN applications is a better and easier approach than using an OpNet.

Dear Mr. Muhammad Usama,

It would be great if he can integrate the pattern of the designed antenna for either RFID or WSN into the OPnet. This is because I think he wants to simulate a real scenario for the complete system including the communication layers and accordingly he can test and/or edit to have better performance.
