Is there no NEC antenna simulation out there which can help designing the inverted F antenna?

Very interesting! This is a lot smaller compared to the patch antenna. But how do you ensure the antennas do not create EMI issues for the components on the PCB? If the antenna is on the same side as the components, can the EM waves generated from the antenna couple back into the components on the PCB?

I am pretty new to this antenna design

may i know how antennae ends are connected to PCB ? Is it by soldering or some spring contacts or any other alternate methods available for this?

The simplified Zin formula is wrong: the tan and cot terms are identical, so the difference cancels and Zin goes to infinity for any value.
