Abstract :
Two low-profile bow-tie antenna designs are presented, printed conformally on high-impedance ground planes (HIGPs). The HIGPs were constructed using two different scale triangular patch mushroom elements which allow for a suitable platform for the active bow-tie antenna. The multiscale nature of the HIGP was utilized to further increase the frequency band-gap of the surface waves, and to enhance the properties of the low-profile bow-tie. The bandwidth of the bow-tie on the HIGP is evaluated and compared with perfect-electric-conductor (PEC) and perfect-magnetic-conductor (PMC) ground planes.
