Need Help with Dipole Design in ADS

Hi

I am new to patch antenna design. I am trying to design a halfwave dipole for 1.5MHZ in ADS.
I have few following questions.

but had few questions
1. in order to draw the dipole legs do i have to draw a rectangle or grab the stripline form the component pallete?

2. how can i do the coax feed in ads layout

3. I am using Rogers 3010 (metal, substrate, metal)
Defined my substrate as follows:

freespace
----strip-cond-
rogers via (Hole)
/////gnd////

4. Please help me with the port definitions?

If possible please provide me with the screenshots or examples if you have any
