Abstract
A very inexpensive and on-site tunable design for a vertically polarized panel antenna system, suitable for the FCC digital broadcast 700 MHz range is provided. Bowtie-like shaped antennas having machine-stampable planar elements with an adjustable separation are configured with a stripline feed. The stipline feed enables easy feeding of doublet systems to allow the configuration of an array of vertically polarized antennas. The various components of the antenna system can be easily tuned, enabling rapid deployment and quick operation.
