A Bow-Tie Cross-Dipole (BT-CD) design is considered as a potentially broadband horizontally polarized (H-Pol) antenna. Even though it is possible to use the BT-CD in both the VHF and UHF bands, the analysis in this effort is solely focused on the 174-230 MHz frequency range in the VHF-band. The BT-CD antenna is designed and optimized in the presence of a generic fuselage using WIPL-D, a Method of Moments (MoM) program. The design and optimization are carried out to obtain 1.6:1 VSWR (i.e., = -12.74 dB return loss) or better, and -5 dBi matched gain or better. A lumped two-element, parallel LC circuit in parallel with the antenna feed, matching circuit is used to compensate for the imaginary component of the input admittance, to obtain acceptable VSWR.
