Abstract

Radial linear slotted array antennas are slotted wave-guide antennas. These antennas are highly efficient and are used to produce circular polarization. In this paper, a slow wave structure is used to increase the tolerable power of the antenna. The use of this structure creates a two-level radial linear slot array antenna. On the slow wave structure, there is a slot plate that is fed by this structure. Both slots perpendicular to each other (to create circular polarization) form a unit of radiation. Radiation units are distributed on a spiral path at regular intervals. This antenna is designed, simulated, and built to operate at a frequency of 9.45 GHz and a radius of 270 mm. According to the simulation results, the reflection coefficient is -18.93 dB, the radiation efficiency is more than 93% and the aperture efficiency is 28.5%. The evaluation of the value of the reflection coefficient for a sample made in the range of 9.385 GHz to 9.417 GHz is less than -10 dB.
