I am am new to RF design and I need to place a chip antenna due to space limitations. The only antenna that is easily available to me has a very weird layout. There is no physical connection from the feedline to the antenna and also the dimensions of this gap is not clearly mentioned. Can anyone please explain what is going on in this layout?
