A novel magneto-electric dipole antenna with dual linear polarization, ultrawideband, and good unidirectional radiation is proposed. It consists of two bowtie-shaped electric dipoles, two orthogonally placed Γ-shaped feeding structures, four parasitic patches, and a metal cylindrical cavity. In order to illustrate the operating mechanism, the radiation field is simulated and analyzed at lower, medium, and higher frequencies. Three operating modes (electric dipole mode, ME dipole mode, and magnetic dipole mode) are found and discussed to show the ultra-wideband radiation. Especially, the ME dipole mode is analyzed in detail. By adding four parasitic metal patches, the boresight gain at the lower and higher bands is enhanced. At 1.75 and 5.6 GHz, the boresight gain improves 1.65 and 2.8 dB, respectively. Additionally, the height of the cylindrical cavity is also analyzed to show its effect on VSWR and boresight gain. Finally, a prototype is designed, fabricated, and measured. Measured results show that the impedance bandwidth for VSWR <2 is up to 92.3% (from 2.1 to 5.75 GHz) and 103% (from 1.8 to 5.65 GHz) at the two feeding ports, respectively. In its impedance bandwidth, the boresight gain is 8.75 ± 1.95 dBi and 8 ± 3.3 dBi at two ports, respectively.And, the radiation patterns in the operating band show a unidirectional radiation characteristic. Therefore, the proposed antenna can be a candidate in the future UWB communication system.

A compact magneto-electric (ME) dipole antenna has been designed to improve bandwidth and gain. The E-dipole and M-dipole elements have separate resonance modes, that is, the E-dipole operates from (4.5 to 5.15 GHz, and 5.36 to 6.4 GHz) and the M-dipole operates from (4.25 to 5.2 GHz). A ME dipole structure is generated when the (E + H) dipole structures are combined. For successful ME coupling, the E-dipole lengths are enlarged at the top and bottom, while truncated in the center. This configuration combines a wide impedance bandwidth with a high broadside radiation gain in a small package. The ME dipole element has a bandwidth of 42.44% from (3.1 to 3.6 GHz, and 4.7 to 6.2 GHz) and gain of 7.1 dBi when the isolated resonant modes of E-and M-dipoles are efficiently induced. To improve overall antenna performance, a metallic reflector is loaded at a height of H air = 8 mm, resulting in an increase in bandwidth of 82.35% from (2.5 to 6.0 GHz) and a gain improvement of 10.2 dBi. A constructed prototype antenna has been tested and found to be in good agreement with simulated results, to be potentially explored in wireless communication systems.
