Literature on tear drop antennas

Hi ,

I am designing a tear drop antenna for the frequency range of 120-300MHz. I am not able to find any literature on tear drop antennas.

Could anyone help me out ?

Thanks in advance

The tear drop antenna basically comes from a bi-conical antenna. I dont know much about the design process. But I hope this link is of some help to you.\
