If we can excite some reasonable fields in the slot (often called the aperture), we have a slot antenna.
Slot Array Antenna
The planar array antenna looks like a flat plate, not a curved surface like a paraboloid. Waveguide slot (also known as "crack") array antennas are the most used planar array antennas.

This work presents a novel CO2 gas sensor based on a slotted polymer-phaseshift Bragg grating (SP-PSBG) waveguide filled with polyhexamethylene biguanide (PHMB) as the sensing medium.
LTCC or LCP, A comparison using cavity backed slot antennas with pin curtains at 60 GHz | IEEE Conference Publication | IEEE Xplore
LTCC and LCP technologies are compared for 60 GHz antenna design in terms of antenna polarization purity and efficiency. Cavity backed slot (CBS) antennas with pin curtain walls are chosen as the antenna element and modelled using the FDTD technique. The performances of the antennas are analysed while changing the substrate used. Substrate losses and conductor losses are calculated and total radiated powers in lossy and lossless cases are studied to reach the final efficiency figures. The CBS antenna on LCP is found to be more efficient and have better radiation properties.
