Abstract
A slotted coaxial antenna design that accomplishes simultaneous UHF and either VHF broadcast, is disclosed. This design combines a DTV channel broadcast system, where the radio frequency signals are in the UHF band (i.e. slotted coaxial UHF antenna), with an NTSC broadcast system where the radio frequency is in the low and mid VHF band (i.e. circularly polarized VHF antenna), using a common antenna aperture.
