circular polarization with PIFA

A dual fed microstrip patch antenna can radiate CP. [ http://www.antennamagus.com/database...age.php?dir=10 ] .

I cannot come up with how this can be achieved on a PIFA.

Maybe you can use two PIFAs, which are arranged perpendicularly (and with 90 degree phase shift) to obtain CP.

can anyone provide document related to design pifa procedure antenna in hfss....

HI jeeudr

whould u have a look at this doc
http://www.jatit.org/volumes/researc.../10Vol4No6.pdf

sorry hiteshhitesh I do,'t work with hfss, I can't help u in this software

best regards

Nice... I forgot that cutting away a triangle from a patch will give CP.

Have u any idea how we calculate the triangle's dimensions?
