Frequency Reconfigurable Low-Profile UWB Magneto-Electric Dipole in VHF Band

Reducing the size of directive and wideband antennas operating in Very High-Frequency band is a major challenge for small satellite integration. At 100 MHz, wavelength 3 m, reduction will make integration easier reduces fabrication costs. The original technique presented this paper enables significant height (up to 50%) crossed Magneto-Electric Dipole antenna while maintaining an ultra-wideband operation bandwidth from 93 360 MHz (118%). proposed based on adding frequency reconfigurable capability structure. has been prototyped experimentally characterized large-sized anechoic chamber. measured results are excellent agreement with full-wave electromagnetic simulated results.
