Abstract
AbstractA slot‐based miniaturized antenna design for CubeSat applications that operate in ultra high frequency (UHF) band is presented. The proposed antenna design consists of a frequency reconfigurable (FR) slot‐based antenna integrated on a Rogers RO4350 substrate. The frequency range covered by the FR antenna is 300–450 MHz. A single varactor diode is used to sweep the frequency of the design. The proposed meandered loop‐slot antenna design is small in size and has planar geometry with overall substrate dimensions of 100 × 100 mm2. The proposed downsized antenna with frequency reconfigurability is ideally suited for small satellite applications in the UHF band, especially CubeSats.
