Dual Band T-Shaped patch antenna design

hi,

i want to design Dual Band T Shape patch antenna (1.8 GHz and 2.4 GHz) in ADS2009. What is the actual shape of such type of antennas?

The main reason of the T shape in the printed antennas is to get dual band resonance. So, the actual shape is: T-shape.

Do you understand why a patch antenna is called a patch antenna? It seems that you do NOT want a patch antenna.

As vfone already mentioned, the T-shape can be used to create dual resonance. I had shown an MWO design example here. The design process is rather similar with ADS.

Good luck!
