Abstract :
We present two low-profile bow-tie antenna designs printed conformally on high-impedance ground planes (HIGPs). The HIGPs were constructed using two different scale triangular patch mushroom elements which allowed for a commensurate platform for the active bow-tie antenna. The multi-scale 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. We evaluate the bandwidth of the bow-tie on the HIGP and compare with perfect-electric-conductor (PEC) and perfect-magnetic-conductor (PMC) ground planes.
