Hello,
I have a question, most of quarter-wave dipole whip antennas are used on the market and their efficiency is quite high. Let's say for example 70%. But the manufacturers gives you the datahseet with all information such as gain, and efficiency with a specified ground plane dimensions. For example 11cm x 11 cm. But if my ground plane is much lower,3xcm x 3cm, how do I know this will reduce too much the antenna efficiency?. In practical, manufacturers use a ground plane with dimensions greater than quarter-wave and so its performance its good (because the large ground plane). But i am worried if the ground plane is much smaller.
Thank you very much
Best Regards,
