Slot antenna - Wikipedia
Abstract. Radial line slot array (RLSA) antenna was initially developed for satellite antenna receivers at a frequency of Ku-band. The success of this development inspired researchers to continue the study to other bands and other applications, such as Wi-Fi at 5.8 GHz.
A Brief Guide to Slotted Array Antennas
Multiple slots act as a directive array antenna and can emit a narrow fan-shaped beam of microwaves. They are used in standard laboratory microwave sources used for research, UHF television transmitting antennas, antennas on missiles and aircraft, sector antennas for cellular base stations, and particularly marine radar antennas. A slot antenna ...

Using the proposed method, slot array antennas with uniform and Chebyshev distribution of slots are designed. Finally, a prototype of a designed antenna is fabricated and its reflection coefficient and radiation pattern are measured to provide an experimental verification.
Slotted waveguide array antennas: Theory, analysis and design
Slotted array antennas are popularly used in radar applications, in which case design standards require mechanical robustness and high gains. Because the power transmission of radar antennas is very high, slot array antennas are preferred alternatives to planar arrays.
