A Novel Miniaturized Planar Ultra-Wideband Antenna [PDF]
IEEE Access, 2019 A novel miniaturized planar ultra-wideband antenna is proposed. The antenna design comprises an electromagnetically coupled structure and a tapered radiating slot, while a triangular slot is etched on the ground plane. The antenna miniaturization is realized by adopting an electromagnetically coupled structure formed by the notched half-ellipse patch ...

Electronics Letters, 2010 An ultra-wideband loop antenna is proposed that is based on a wavelength loop antenna and a slot antenna. The self-complementary principle is applied to the designed ultra-wideband antenna. The antenna operates as a loop antenna in the low frequency band (0.3-1-GHz) and as a slot antenna in the high frequency band (1-14.2-GHz).
