    Waveguide slot antennas are a type of microwave antenna that use a hollow metal tube, called a waveguide, to transmit and receive electromagnetic waves. They have slots cut along the length of the waveguide, which act as radiating elements. Waveguide slot antennas have some advantages over other types of antennas, such as high efficiency, low loss, and wide bandwidth.

    A new design of circularly polarized (CP) patch-helix hybrid antenna with small ground is presented. The proposed antenna consists of a driven patch, a parasitic patch, and a helix connected with the parasitic patch. The hybrid antenna has a relatively small ground, making the overall antenna compact. The proposed antenna can be packaged in a thin cylinder and can be easily mounted in the space-limited systems. Good impedance matching was achieved by capacitive coupling between the driven patch and the parasitic patch, while high gain was obtained with a small ground due to relatively uniform current along the helix.
