Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.

A novel design of dual-band slot antenna with a circular patch for radar applications is presented and studied. It is fed by a micro-strip line and built on a FR-4 substrate with a whole size of 18 x 30 mm2. A dual band printed antenna is created by introducing slots on the radiating element.
Design of Substrate Integrated Waveguide Multi-band Slots ... Abstract—In this paper, the design of slots array antennas based on Substrate Integrated waveguide (SIW) has been analyzed and simulated. A waveguide slot antenna has a vertical row of slots along the length of a vertical waveguide, with the array of slots increasing the gain by flattening the vertical beam. Design of Slotted Waveguide Antennas with Low Sidelobes ...
For the slot antenna, the resonant conditions arise from the circumference of the slot, which is proportional to the guided wavelength [6]. The input return loss level and the resonant frequency of the proposed design will vary with total length L and width W of the substrate.

The design of a printed wide-slot antenna with a rotated slot is pre‐ sented in [20]. The impedance bandwidth of the antenna varies with the rotation angle of the slot and can maintain 50.2% with suitable angle. More recently, the design of a printed wide-slot antenna for wideband applications is proposed in [21].
