First design patch antenna for your desired frequency.
Then design a transmission line(microstrip) of length lambada by 4.( remove ground plane of this microstip line)
You can place some part of transmission line on patch & see what happens. The advantage of this EMC antenna is you can change position of feed to get good result.
If i want to design the patch antenna, the due to square patch i can not apply transmission line theory because length and with is same so it will not resonate at desired frequency. so i have to go for the other model
