A simple ultra-wideband magneto-electric dipole antenna utilizing a differential-fed structure is designed. The antenna mainly comprises three parts, including a novel circular horned reflector, two vertical semicircular shorted patches as a magnetic dipole, and a horizontal U-shaped semicircular electric dipole. A differential feeding structure working as a perfect balun excites the designed antenna. The results of simulation have a good match with the ones of measurement. Results indicate that the designed antenna achieves a wide frequency bandwidth of 107 % which is 3.19~10.61 GHz, when VSWR is below 2. Via introducing the circular horned reflector, the designed antenna attains a steady and high gain of 12 ± 1.5dBi. Moreover, settled broadside direction main beam, high front-to-back ratio, low cross polarization, and the symmetrical and relatively stable radiation patterns in the E-and H-plane are gotten in the impedance bandwidth range. In the practical applications, the proposed antenna that is dc grounded and has a simple structure satisfies the requirement of many outdoor antennas.

“…Its bandwidth for VSWR < 1.5 was 0.94 GHz to 4.27 GHz, or 4.5 : 1 in bandwidth ratio, but its profile was high, nearly 45 mm. A novel composite corrugated-reflector [8] was introduced to improve the directional radiation band of the printed dipole antenna and reduce its profile to 21 mm high. However, its radiation pattern was just stable from 2.5 GHz to 6.0 GHz.…”

Abstract-An improved directional equiangular spiral antenna with wide CP band and high gain is proposed, in which the impedance bandwidth is 2 ∼ 12 GHz, CP bandwidth, 4.5 ∼ 7 GHz, and gain 6 ∼ 9.5 dBi. The antenna includes 4 layers. The top layer is equiangular spiral antenna, and the bottom layer is the ground. The middle two layers are parasitic metal films with irregular rectangular holes, which are introduced to improve the performance of equiangular spiral antenna and reduce the profile. The measured results are in good agreement with the simulated ones.

“…Researchers have proposed a variety of UWB antennas, such as monopole antenna [1], dipole antenna [2] and dipole directional antenna [3,4]. These antennas all bear some common characters: wide impedance bandwidth but radiation pattern bandwidth far narrower than the former [5,6].…”

Abstract-In this paper, an ultra-wideband (UWB) printed dipole antenna with semicircular dipoles is presented. A balanced microstrip line is used for feeding the dipole antenna. By introducing the loading disc, an ultra wide frequency band from 3.2 GHz to 15.6 GHz with VSWR < 2 is obtained. Through analyzing the surface current of the antenna, the equivalent array radiation models of standing wave current and traveling wave current are obtained. These models can well explain the antenna's radiation characteristic, which matches measured results well.
