We propose a wideband and dual polarization open-ended waveguide. Because excitation probes of the waveguide and strip lines connected to the probes are formed in the dielectric substrate, multiple elements can be fed by using the branched strip line. So the proposal makes it easy to construct array antennas. In order to array the antennas including the strip lines with suitable spacing, we propose...
We propose a wideband and dual polarization open-ended waveguide that makes it easy to construct array antennas. The proposed device stacks feeding circuits for both polarizations on different substrates. In order to equalize the distances from the excitation probe of each polarization to the electrical ground, we propose to place metal slits on the antenna ground. This offsets the characteristic...
