A Dual-Band Dual-Beam Shared-Aperture Antenna for Multiorbit Satellite Communication
Abstract
In this letter, a dual-band, dual-beam shared-aperture antenna combining a variable inclination continuous transverse stub (VICTS) antenna and a patch antenna array (PAA) is proposed for simultaneous connections with two satellites. The VICTS generates a Ku-band scanning beam, whereas the PAA provides a K-band fixed-direction beam. By mounting the PAA on the surface of the radiating layer of the VICTS antenna, a shared-aperture configuration is achieved. The feeding network of the PAA is specially designed, and long slots are etched on both the substrate and the ground plane to effectively mitigate the interference. To verify the proposed design, a prototype was fabricated and measured, showing good agreement between the measured and simulated results.
