Switchable T-Slot for Dual-Circularly-Polarized Slot-Array Antennas in Ka-Band

[EN] This letter presents two slotted array antennas working in the Ka-band with switchable circular polarization capability. The first prototype is a series-fed slotted-waveguide linear array composed of ten T-shaped slots. The second antenna is a 2-D array with 2 x 2 T-shaped slots fed by a corpor...

The first prototype is a series-fed slotted-waveguide linear array composed of ten T-shaped slots. The second antenna is a 2-D array with 2 x 2 T-shaped slots fed by a corporate distribution network.
