An ultra-wideband Vivaldi antipodal antenna with high gain is presented. A CSRR array and T-shaped strips were developed to embedded in the tapered slot antenna, which improves VSWR and gain performances, especially in the low frequency regions. Simulation results have been presented with a fractional impedance bandwidth of 186% from 1 GHz to 28 GHz for VSWR<2 and gains better than 2dB. The simulated antenna gain of up to 17.3dB is achieved, making the antenna suitable for metrology and test in the fifth generation mobile communication.

In this paper, a low-profile lightweight wide scanning microstrip antenna is proposed, which can be widely used in space-borne and airborne platform. The results of simulation indicate that the antenna achieves 15% bandwidth while scanning to ±60° in E-plane and ±20° in H-plane, subject to active VSWR<2.5. The gain is within 3 dB of the theoretical limit in all scan-planes. Measured results are presented for a prototype 8× 4 array, showing good agreement with simulation.

In this letter, a differentially coplanar-fed antenna using integrated substrate gap waveguide (ISGW) is proposed for millimeter-wave applications, which has high gain and low cross polarization. The antenna consists of the differential power divider and radiation patch, and the power divider is deployed to excite the differential feeding antenna. The differential power divider is designed using rectangular-shaped coupling slot to achieve a stable 180° phase imbalance and 15% fractional operating bandwidth. The differentially coplanar-fed cross-shaped patch antenna has high gain and good radiation patterns. A fractional bandwidth of about 8.3% at the center frequency of 24 GHz and a peak gain of 10 dBi are obtained.

In this paper, a substrate integrated waveguide (SIW) slot antenna array combined with fin-shaped heatsink is designed. It consists of four 1×8 SIW slot antenna elements. The heatsink structure enclosed in the design enhances heat dissipation capability of the antenna array while maintaining the radiation performance of the original structure. The simulated −10 dB impedance bandwidth of the antenna array with and without heatsink are 6.5% and 6.4%, respectively. In addition, the realized gain are 19.16 dBi and 18.04 dBi at 28 GHz, respectively.

This paper presents the defected ground structure (DGS)-based band-stop filter (BSF) which is developed using RO4350B and has a small board area of 20 × 10 mm2. The performed analysis of the proposed DGS shape shows that the size of the DGS has a huge impact on the quality factor. The cascades of the defects and incorporation of external capacitors aid in achieving the dual-band BSF. Furthermore, the developed BSF demonstrates the ability of wide-band rejection from 6.45 GHz to 12.75 GHz.

This paper presents the retrospect and prospect on the trend of some representative mm-Wave antenna solutions, AiP, AiME, AiAiP, and AoD, to cellular phones. The main trigger factors for generation of these solutions are the constrains (e.g., the path losses and blockage) on the mm-Wave applications. Strategically, the underlying philosophy for the above solutions is the part integration; tactically, the underlying philosophy for design variants of the solutions is the capability expansion.

A varactor-tunable bandpass frequency selective surface with wide tuning range is presented in this paper. The proposed Frequency Selective Surface (FSS) is composed of three stacked metallic layers. In the top and bottom layers, four varactors are loaded between the cross-shaped patch and the inductive wire grid of the FSS unit cell, respectively. The wire grid in each layer is connected by a via, which forms a bias network. The advantage of this network is that no additional DC bias network is needed, which can effectively reduce the frequency offset caused by DC bias. The passband can be tuned by changing the capacitance of varators loaded in the unit cell. Full-wave simulations show a 59% wide tuning range from 11.4 to 6.2GHz with an insertion loss between 0.3-2.3dB by changing the varator capacitance from 0.1 to 0.4pF.

An active bandpass frequency selective surface (AFSS) is proposed in this paper based on the coupling principle, with good angularly and switching stabilities. Taking the wrench -shaped patch as the basic unit, AFSS tuning function is realized by changing the traditional structure and arrangement of wrench -shaped patch. Parameter analysis and equivalent circuit model are illustrated to explain the resonance behavior of the proposed AFSS. Numerical analysis software CST showed that by rotating the upper patch at 0°—120°, AFSS can be tuned in 6.36GHz -- 8.81GHz. It is demonstrated that the insertion loss can be reduced by changing the arm width of the unit, and the insertion loss can be kept within a certain range during tuning. According to the simulation and calculation, the FSS structure maintains good angularly stability within 0°—80° and has good switching stability during frequency band switching.
