Hi guys,

I need to deisgn a notched patch antenna to excite the RHCP at 1.2 GHz.

Unfortunately I don't remember the design formulas...

Can anyone provide me with the following data:

- patch radius;
- probe position;
- area of the two equal cuts.

Thanks in advance,
Lupin
 

Hi Lupin,

You can read design guideline of CP patch antenna in Handbook of Microstrip Antennas Edited by JR James and PS Hall in Chapter 4 (M. Haneishi and Y. Suzuki).

rgds,
