I've been trying to design an omnidirectional PCB inverted-F antenna for a bluetooth project. The aim with the design is to ensure the best range possible with the space I have; Ideally an average gain of >1dBi. I've come up with a design that I think may work, but I really am struggling to verify if it will perform as required.
Here is the design layout (the tail connects to ground, just doesn't look like it here)
I know antenna design is not a trivial task, but will this antenna work? if not, what might need modifying to make it perform?
Are there any alternative antennas out there that may fit my performance and spatial requirements? I looked at a TI IFA design but it's just slightly too large for the ~34mm x 5.5mm I have available.
