Abstract

In this paper a waveguide antenna to create a saddle shaped pattern for remote sensing satellite applications has been introduced, and a method to excite a waveguide as feeding X-band antenna with the aim of achieving circular polarization has been presented. With the use of a circular microstrip probe, the mode inside the cylindrical waveguide is stimulated in such a way that the antenna has circular polarization with only one feeding input, and in addition, the input impedance of the antenna is fifty ohms. To achieve the saddle-shaped pattern, plus-shaped guides have been used. These guides are printed as microstrips on the Rogers 5880 substrate. The innovation of this article is in the simultaneous use of directional elements to create a saddle-shaped pattern and a circular probe to create circular polarization in order to design a suitable antenna for LEO remote sensing satellites. After simulation, the antenna was fabricated and tested. The test results show that the antenna has a real gain of more than 3 dBi at angles of θ = ±65. The axial ratio of the antenna is less than 3 dB in the working frequency for θ values between ±50, which shows that the antenna has a desired circular polarization in this θ angle range.
