["neilmallik" <neilmallik@xxxxxxxxxxx>]

Hi all,

With regard to my previous message, I have to build a microstrip 
antenna that has broadband characterisitcs. From some of the comments 
I have received, I understand that quarter-wave matching does provide 
a narrowband characteristic. 

I would like to know, what types of patterns are useful when 
designing a microstrip antenna (preferably smaller than 5cm x 5cm) 
for the IEEE802.11a range. 

I am currently looking into the bowtie patch, but I have no idea on 
how I would feed it. I have attached a picture in a separate message 
(named "picture of bowtie"). Any idea on what dimensions I should 
use? I know that arbitrary values are useless. The permittivity and 
the height of the substrate can be a suitable value of your choice. 

Any comments are welcome.

Thanks in advance.

Neil.
