A dual-frequency satellite antenna loaded with a double-arrow array
A dual-frequency satellite antenna is designed for the applications of global navigation satellite systems (GNSSs). The proposed antenna consists of a square radiation patch with a double-arrow array loaded, which is formed by introducing anchor-like arrows as resonators at four corners respectively. The double-arrow array, with the adjustable lengths of its internal and external branches, is loaded on the patch to control the radiation properties flexibly. The simulation results show that the operation frequencies covering B3 and L1 bands, i.e., at 1.268 GHz and 1.575 GHz, can be acquired. In addition, in order to explain the relationship between the resonances and structure dimensions, the parametric studies based on the gap size of the anchor-like arrows and the length of the resonator are also discussed. It is clear that the demand of GNSS applications could be satisfied, according to the surface currents and antenna gains at different frequencies demonstrated and analyzed in detail.
