|A hybrid-fed dual-polarized antenna with matesurface coverage is proposed in this paper, which can be used for 5G mobile communication base station antennas. By placing the two feeding ports on different layers of dielectric plates in an orthogonal manner, and using electromagnetic coupling and slit coupling for feeding respectively, the antenna can achieve inter-port isolation higher than 35 dB in the operating frequency band. In order to widen the bandwidth and obtain higher gain, the metasurface covering unit is loaded above the patch. The metasurface layer contains an array of 5 (cid:2) 5 square patch units printed on the top surface of the dielectric plate. The measurement results show that the proposed antenna has an impedance bandwidth of 12% (3.24 to 3.66 GHz). In addition, the antenna obtains a stable gain of about 5.32 dBi at 3.5 GHz. The proposed antenna meets all the requirements of base station antennas and can be a promising candidate for application in 5G base station systems.

|In this paper, a planar wideband antenna array with wide scanning angle in both E - and H -planes is proposed. The dipole antenna is used as an essential element of the array. To enlarge the scanning angle of the array, two layers of frequency selective surface (FSS) superstrates are loaded on the top of the antenna elements. A conducting-patch with shorting pins is loaded under the unit patch to enlarge the bandwidth of the array. Both simulated and measured results have con(cid:12)rmed that the proposed antenna array can scan up to 85 ◦ and 70 ◦ in the E - and H -planes from 8 GHz to 11 GHz, respectively.

—A novel microstrip loop-type resonator with four resonant modes is proposed in this letter. The resonator is formed by a loop-type microstrip line loaded with four shorted stubs. It has a symmetrical structure, thus the odd-even-mode method is adopted to implement the resonant analysis. The novelty of the proposed resonator lies in two aspects. One is that its resonant frequencies can be adjusted in a more flexible way. The other is that its resonant modes have a uniform electromagnetic field distribution, which is beneficial for the excitation of resonant modes. For the purpose of demonstration, based on the novel resonator, a single-band bandpass filter with four transmission poles and a dual-band bandpass filter with two transmission poles in each passband are constructed. Additionally, source-load cross coupling is introduced, and several transmission zeros are generated in the stopband, which improves the out-of-band performance greatly. The designed single-band filter has the central frequency of 2.4 GHz and fractional bandwidth (FBW) of 4.5%, and the dual-band filter has the central frequency of 1.8/2.4 GHz and fractional bandwidth of 2.0%/2.5%. The two bandpass filters are designed, fabricated, and measured. Agreement between the simulated and measured results verifies the effectiveness of the proposed resonator and filters.
