“…The use of dualband antennas decreases the number of antenna elements employed and reduces the cost and installation space for the base-station system. In the last few years, many studies have been carried out on the dual-band MED antennas [5][6]. In [5], a dual-layer structure is used to realize dualband MED antennas that have fractional bandwidths of 47.5% (1.70-2.76 GHz) and 30.2% (4.50-6.10 GHz), and corresponding peak gains of 9.7 dBi and 8.5 dBi, respectively.…”

The paper presents the results of a novel high-gain dual-band magneto-electric dipole (MED) antenna. The antenna comprises two pairs of horizontal metal plates of different heights that are excited by a Γ-shaped feedline structure. The antenna is entirely made of metal plates. Compared to traditional MED antennas the proposed design exhibits dual-band operation with higher radiation gain and whose frequency ratio can be modified by simply adjusting the heights of the two magneto-electric dipole segments. This feature is necessary for cellular base-station applications. The operation and characteristics of the antenna are validated by measurements. The measured results confirm the proposed antenna achieves fractional bandwidths of 13.31% (801.9-916.2 MHz) and 19.76% (1710.7-2085.7 MHz) for S11 ≤-10 dB. It has stable unidirectional radiation patterns and optimum radiation gains of 9.2 dBi and 7.8 dBi at the first and second operating bands, respectively.

In this article, a compact dual-band magneto-electric dipole (MED) antenna array with high gain is proposed, which is fed by a 1-to-4-way feeding structure composed of substrate integrated waveguide (SIW) aperture-coupled. The dual-band MED antenna consists of a pair of U-shaped patches of different sizes used as electric dipoles and two pairs of vertical metalized vias work as magnetic dipoles. By analyzing the working mode of the MED unit at each resonance frequency and the complementary principle of radiation patterns, the dual-band characteristics of the antenna are further illustrated. Measured results of the fabricated antenna array show that -10 dB impedance bandwidth is 12.5% (from 22.5 to 25.5 GHz) with a peak gain of 11 dBi in the lowfrequency band and 5.9% (from 40.5 to 42.9 GHz) with a peak gain of 10.5 dBi in the high-frequency band. Moreover, the radiation patterns in E-and H-planes are almost symmetrical at two operating bands with the maximum gain in the z-direction. The proposed dual-band MED antenna array has the merits of high gain, easy integration and simple structure.antenna array, dual-band, high gain, magneto-electric dipole, substrate integrated waveguide (SIW)

“…Recently, dual-polarized antennas have been widely studied and adopted in wireless base station systems. They can mitigate the multipath fading problem and increase channel capacity by means of polarization diversity [4][5][6]. For the dual-polarized antennas to work effectively, wide impedance bandwidth, high isolation and low cross-polarization level are required.…”

A differentially fed dual-polarized patch antenna with wide bandwidth is presented in this paper using Substrate Integrated Waveguide (SIW) technology. The antenna comprises a circular patch radiator, a square SIW cavity, and four symmetric arc-shaped slots. The circular patch is internally embedded in the square SIW cavity with a surrounded ring slot. Two pairs of differential L-shaped probes are used for the excitation of the differential signals. These signals excite the orthogonal linearlypolarized modes. The dominant resonant mode of the circular patch resonator (TM 11) and the modes of the SIW cavity (TE 110 and TE 120 /TE 210) are employed to achieve effective radiation under these resonances. Besides, four symmetric arc-shaped slots are etched on the top surface of the cavity to enhance the impedance bandwidth. The resonant properties of these modes are studied based on the cavity model theory. Then, their resonant frequencies are discussed to provide information for designing and optimizing such an antenna. Finally, the feeding positions of the differential L-shaped probes are investigated for good impedance matching. The proposed antenna has been fabricated and measured. The measured results show that the proposed antenna achieves a wide impedance bandwidth of about 64.8% (4.37-8.56 GHz) and 64.2% (4.48-8.72 GHz) for horizontal and vertical polarization, respectively. High differential isolation of better than 30 dB and low cross-polarization are obtained by adopting the differential feeding mechanism. Due to the SIW cavity-backed structure, the antenna shows unidirectional radiation patterns and low back-lobe radiation, making it conveniently integrated with microwave differential circuits and applied in the base station systems.
