This is my first attempt in designing a pcb layout for a gps chip antenna. PCB is two layered. All the components (including the antenna) are on the bottom layer. I have assumed it to be a "co-planar wave" transmission line (NetANT_2). The width of the feed line is calculated using the "Saturn PCB design toolkit".
My concern is, can this transmission line be considered as "co-planar wave"? as I think there is no sufficient ground plane to left of the feed line. Really appreciate the help. Thanks.
EDIT: The length of the feed line (NetANT_2) =138mils (3.505mm), width= 33.325mils (0.84mm). The ground plane gap is 8mils(0.203mm). substrate height 0.66mm. U10 is a LNA(MAX2659).
