Abstract :
Two wideband antennas sharing a common aperture are presented. One antenna consists of an electrically loaded rectangle monopole, an electrically loaded inverse L-shape monopole, and a lowpass matching network between the two monopoles. It covers 30-600 MHz (VSWR <3) with band-rejection characteristic in 86-110 MHz. The other one is a planar open-sleeve monopole, which covers 820-1200 MHz with VSWR<2. These two antennas are integrated in an aperture with size of only 420 times 200 mm2. Both antennas are planar, which are promising candidates for either vehicular or airborne applications.
