Abstract

This paper presents a slitted, dual-band, square, microstrip patch antenna for CubeSat application. Compared to recently reported works, the originality of this design is the capability to operate at dual-band UHF, using a single feeding point, and, in this way, reducing the risks inherent to wire antennas. The antenna resonates at 399.025 MHz and 431.600 MHz frequencies and it is limited at 100 mm x 100 mm area in a CubeSat face. Forty slits, on the perimeter of a square patch, ten slits on each edge, and a high relative permittivity substrate was used to decrease the operating frequencies. An asymmetry between the slits allows the operation in two different frequencies. This slitted square patch may be up to 48% smaller in area than a square patch without slits, both with the same operating frequency. The design, simulation, manufacturing, and measurement details are presented. Simulated and measured results reveal that the gain, the radiation patterns, the bandwidth, and other parameters are adequate for CubeSat applications.
