A COMPACT ULTRA WIDE BAND ANTENNA FOR TRANSMISSION AND RECEPTION OF RADIO WAVES

摘要

A stacked disk loaded antenna (80) that uses a dual double tuned impedance matching networks to broadband match the radiation resistance to a 50 O port. Using two antenna elements (31, 64 ) in a stacked construction results in the antenna effectively combining the bandwidth ranges of both the antenna elements and removes the requirement for external tuning, which will add weight to an antenna structure. The stacked antenna system can be employed within communication systems operating within the HF and UHF bands.
