Printed UWB Antenna Operating Over Multiple Mobile Wireless Standards

In IEEE document, Printed UWB Antenna Operating Over Multiple Mobile Wireless Standards, I have the problem to made another side which is right side of spline whereas Left hand side is made correctly in HFSS. How to make it?

Secondly how to made two bottom rectangles which is back side.

Thirdly, one large rectangle has to be made but I have doubt that either I will draw box or rectangle but hfss shows that rectangle with equal side is not possible.

PDF file is also attached.

Please help me for three problem that i have discussed above.

How far exactly have you progressed in your hfss design ? The previous post is not very clear. If you upload your hfss file, I can take a look at it.
