Slotted Waveguide Array
Hi, I have a question about the slotted waveguide array.
By cutting the slots along the waveguide broad-wall, the power can be radiated out to the free-space. However, although the impedance bandwidth of this kind of antenna is pretty good, but the main-beam angle is also steered off the zenith at the band-edge.
I am wondering are there any way to overcome this issues, means that make the main-beam of the slotted waveguide point to a fix angle over about 5% bandwidth.
Thanks.
