["neilmallik" <neilmallik@xxxxxxxxxxx>]

Hi all,

I have just designed a broadband patch antenna, which should be 
resonant in the 5.1 - 5.8GHz range (IEEE802.11a). This was designed 
in ADS.

I have fed the patch using impedance matching (lambda/4), and yet I 
am not achieving a broadband bandwidth (expected). I have now lost 
faith in ADS and in the design I am using.

Can anyone suggest any other patch designs which have broadband 
characteristics in the in the IEEE802.11a region?

Any quick response is greatly appreciated.

Thank you.

Neil
