Abstract
A periodic leaky wave antenna having series fed 7-unit cell structure is proposed here. The design of the proposed antenna is mirrored E-shaped antenna. In this work, directivity and efficiency of the antenna are improved by etching rectangular-shaped patch added with small triangular patch and loading of balanced sorting pins. Antenna is working efficiently in range 21.1 GHz to 26 GHz having center frequency of 24 GHz. It is having a high scanning range 70° (from −30° to 40°) and improved directivity. Efficiency is the ratio of conversion of power of accepted RF signals into radiated signals, and efficiency of the designed antenna is 90%. Gain of the proposed antenna is 15.1 dBi. Circular polarization is also obtained at different frequencies, i.e., 21.1 GHz and 24.5 GHz. The working of proposed antenna is effective as well as efficient, and radiation is circularly polarized.
