Halo antenna - Wikipedia A halo antenna, or halo, is a horizontally polarized, omnidirectional 1⁄ 2 wavelength dipole antenna, which has been bent into a loop with a small break on the side of the loop directly opposite the feed point. Quad antenna - Wikipedia Like a Yagi–Uda antenna ("Yagi"), a quad consists of a driven element and parasitic elements; however in a quad, each of these elements takes the form of a loop of wire, which may be square, round, or some other shape.

Then the advantages and disadvantages of the antenna are discussed and the methods of analysis used for the MPA design.
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.
