Broadband Grounded Vertical Antennas for 30-180 MHZ (VHF)
Abstract
The invention is an antenna with broad frequency range to act as either source antenna (transmitting signals) or receive antenna (receiving signals), with a known gain value. The antenna is separated into two variant antennas: one to cover 30-60 MHz and one to cover 60-180 MHz. Because this antenna is broadband in frequency, no matching or physical tuning is necessary, allowing for straightforward testing. The antenna is designed for vertically-polarized electric fields at/on a general ground surface with the antenna pattern being omniazimuthal up to 15 above the horizon and predominantly less than 4:1 standing wave ratio across the band. The antenna utilizes simple elements to achieve desired performance across its frequency band: a combination of one or two cone elements and a linear whip on top of a square ground plane.
