Compact and low profile shared aperture dual-band antennas are presented for space applications. The shared aperture antennas consist of a regular stacked patch for the high band and two channel shaped patch antennas with differential feed for the low band. The mutual coupling between antennas working at two bands is suppressed by using antennas with dual-resonance for out-of-band radiation suppression.
A prototype operating at low band (1.04–1.11 GHz) and high band (1.19–1.35 GHz) is fabricated and measured. The measured results generally agree with the simulated results, making it a candidate for shared aperture dual band applications.
