The previous generations of communication networks are almost packed in the UHF band. Recently, the Ka-band has been widely discussed in potential 5G standard, because of the spectrum practicality and the small size of the components. In this paper, we proposed a dual beam microstrip antenna, which can be used in 5G mobile communication systems. The antenna consists of three stubs, a rectangular radiating main patch structure and symmetrically arrangements of two small patchs, which can be made part of radiating element. The simulated result shows that the designed antenna work at 28 GHz, which has a bandwidth of 0.88GHz. The proposed antenna can generate dual beam in the direction of ϕ = 0° and θ = ±30° at 28GHz, having maximum gain of 8.2dB and 8 dB, respectively.

This paper presents the design of simple Metasurface that can rotate the polarization of linearly polarized incident EM-wave to its cross-polarized component. The surface is composed by a simple dumbbell-like metallic resonator etched on the top surface of a PEC backed dielectric material. The proposed dumbbell-like unit cell has four plasmon resonance frequencies at about 88GHz, 91GHz, 92.6GHz and 93GHz. The results show that the proposed surface can realize a cross polarization conversion efficiency of more than 93% from 87.2GHz to 93.4GHz under both x- and y-polarized incident EM waves. A sample is fabricated which has 16×16 unit cells and occupied an area of 32×32 mm2. Both full wave simulations and experimental results are used to characterize the proposed surface.

The conventional UHF RFID tag antennas are usually without good circular polarization characteristics on the flexible surface under the condition of miniaturization. In this paper, a novel flexible miniaturized square-ring UHF RFID tag antenna with circular polarization operating at 912MHz-934MHz is proposed. This tag antenna consists of a chip, a double feed line, a meander line, and an inductive matching loading structure. The simulated results indicate the proposed antenna is more suitable for working on flexible surfaces than the compared tag antenna. The measured result shows the reflection coefficient of RFID antenna within 840MHz∼960MHz meet the target requirements.

In this paper, a leaky wave antenna based on Composite Right/Left-handed Structure(CRLH) is proposed. The equivalent series capacitance in the CRLH is realized by the ring slot on the microstrip and the metal vias realizes the equivalent shunt inductance. The special structure of CRLH makes the propagation constant in the region of lower frequency negative, showing the left-handed characteristics, and the phase velocity and the group velocity have the opposite direction. In the higher frequency region, the phase velocity and group velocity have the same direction, showing the right-handed characteristics. The structure achieves a frequency scanning angle of −60 degrees to 30 degrees and it achieves high gain in the working band of the antenna.

A 2×2 circularly polarized magnetic-electric dipole array which adopts sequential-rotated feeding technique to broaden the bandwidth with the total size of 1.68λ0 × 1.68λ0 × 0.08λ0 is presented in this paper. The antenna element utilizes an obtuse-triangular structure to reduce the antenna profile to only 0.08λ0. The simulated results show that an impedance bandwidth of 21.4% (VSWR<1.5) from 1.88GHz to 2.33GHz is achieved, which is overlapped by the 3dB axial ratio bandwidth of more than 28.6% from 1.8GHz to 2.4GHz. A stable gain of 11.6 ± 1.2dB is realized in this operation frequency bandwidth.

In this contribution, characteristic mode analysis is adopted to analyze antenna coupling in a systematic way. The mutual admittance is separated into several fundamental modes, and the contribution of each mode is evaluated through the modal mutual admittance (MMA). Some higher order modes, which contribute little to the in-band radiation but much to the out-of-band coupling, are discriminated and suppressed using lumped loads. For monopole-type antennas deployed on platform, the weighted engencharge distribution helps determining the suitable deployment positions for a smaller mutual coupling.

A low profile broadband dual polarized patch 1×4 sub-array in a 1-D infinite array is presented. It uses double differential L-probe coupled feeding technique to reduce cross-polarization levels and to enhance impedance bandwidth. The total size of proposed sub-array is 143×612.5×26mm3. The simulated results indicate a 14-dB impedance bandwidth of 300MHz (1.1–1.4GHz) for both polarizations. The isolation is better than 51dB. The realized gains are from 11dB to 13dB. The gain difference between the two polarizations is less than 0.25dB. The relative cross polarization levels are −37dB within the HPBW range for H-pol, and −40dB within ±30°for V-pol.

The antenna test is usually considered a different step compared to the antenna design. In this contribution a novel approach is proposed, in which antenna testing is part of an integrated product development process of the radiating system. Possible problems affecting the antennas are identified during the design. A set of bases are obtained for each cause of uncertainty or possible failure of the antenna. The union of such sets gives a dictionary of over-complete bases, from which a suitable subset able to represent the field radiated by the Antenna Under Test (AUT) is extracted using the Orthogonal Matching Pursuit (OMP) algorithm. This approach allows to optimize the measurement time in the antenna test procedure.

In this paper, a novel printed quasi log-periodic dipole antenna is proposed. It is based on a conventional log-periodic dipole antenna (LPDA) with modifications of the lengths of the dipole units. The proposed antenna has an exponential profile by cutting the opened ends of the radiating dipoles. Compared to the corresponding LPDA, it has improved gain of about 1.0–2.0 dB at high frequencies with the same antenna size and remains good matching in the operation band.
