A small and compact microstrip-fed monopole antenna, which consists of a rectangular patch and a truncated ground plane, is presented for ultra wideband (UWB) application. The antenna occupies a compact size of $mathbf{26 mmtimes 32 mm times 0.762 mm}$, including the feeding mechanism. Proposed antenna, which is printed on Rogers substrate with a relative permittivity of 2.2 has been easily fabricated and has low manufacturing cost. Measured results show good agreement with the simulated results and the proposed antenna has an impedance bandwidth of 3.8-14.8 GHz for a voltage standing-wave ratio less than 2. Furthermore, good radiation patterns indicate that the proposed antenna is well suited to be integrated within various portable devices for UWB application.

This paper presents a high-efficiency broadband Doherty Power Amplifier (DPA) architecture for the S-band covering from 3.3GHz up to 3.55GHz, aiming on 5G applications. The DPA based on low-pass like output matching structure and modified higher back-off combining network was designed and fabricated. Continuous Wave (CW) measurement results show that the proposed PA delivers a saturated output power of more than 47.5dBm, and holds a Power-Added-Efficiency(PAE) of more than 600% (at 7.5dB back-off) at all frequencies except 3.3GHz, which is about 53% with a saturated PAE range of 47%-58% within bandwidth. Also the 20 MHz LTE modulation signal measurement achieves the high efficiency and linearity performance of DPA, with a PAE of more than 50.6% at 8.5 dB back-off and an ACPR of -46.7 dBc.

A new method aimed to design wideband microstrip antennas with low radar cross section (RCS) is proposed in this paper. The reflection phase inverse points and the 0° phase reflection points of the AMC unit cells can be designed to obtain 180°(± 30°) effective phase difference over broadband frequency range. The antenna is fabricated on a chessboard configuration which is structured with two AMC unit cells. Both simulated and measured results show that the proposed antenna possesses more than 7 dB RCS reduction with 69.2% relative bandwidth for both polarizations, covering the working band of the original antenna. The maximum reduction is 31.4 dB. Meanwhile, the radiation properties of the antenna are almost not changed.

In this paper, a novel wideband omnidirectional circularly polarized (CP) antenna is proposed. The designed antenna consists of the $2times 2$ dipoles. The $2times 2$ dipoles are fed with equal amplitude and phase arranged in circles. And the current directions of the two pairs of opposite dipoles are opposite to each other, which generate the omnidirectional CP. The VSWR of proposed antenna is less than 2 within 4.33GHz-5.38GHz, whose relative bandwidth is 21.6%. The 3-dB axial ratio bandwidth is 4.53-5.84GHz (25.3 %). Due to the omnidirectional radiation of the proposed antenna, the antenna can be used in indoor communications and automotive vehicles mounted antenna.

In this paper, a novel high efficiency millimeterwave bean steering antenna array for 5G communication systems is presented. The design idea of a single antenna element comes from the UWB disc monopole antenna. A 1×8 antenna array is designed and simulated. Simulated results show that the reflection coefficient is lower than -10dB within the frequency range from 20 to 30.5 GHz, which covers the 24.25-27.5 GHz band proposed by lTV and the 27.5-28.35 GHz band proposed by FCC for 5G. The total radiation efficiency of the proposed array is higher than 80% in a wide frequency range from 25GHz to 30GHz. The gain of the antenna array varies from 8.23 to 9.91 dBi over the frequency range of 25–30 GHz. The simulated results also illustrate good beam steering performance across the wide frequency band. The main beam can scan from -50°to 50°with 1.68 dB gain fluctuation in the E-plane.

A newly developed high power ultra-wideband solid state amplifier is presented in this paper. We discuss three main techniques, thermal design, ultra-wideband power combining and multifunctional power management. We've designed a high performance radiator with several bended heat pipes located both on surface and inside the radiator, this new radiator can quickly dissipate 1000W heat and control the temperature rise under 30 degrees with proper fans. And also a new ultrawideband power combiner is developed. With one N-type connector and twenty 3.5mm connectors, it can efficiently work at the band range of 6GHz-18GHz. For the huge power management, we've designed a multifunctional power management module to keep the whole system working safely. We've finally assembled the complete power amplifier system. The experimental results show that the typical output power of 150W is successfully achieved.
介绍了一种新型的大功率超宽带固态放大器。讨论了三种主要技术:热设计、超宽带功率组合和多功能电源管理。我们设计了一种高性能散热器,在散热器的表面和内部都有几个弯曲的热管,这种新型散热器可以快速散发1000W的热量,并通过适当的风扇将温度上升控制在30度以下。并研制了一种新型的超宽带功率合成器。采用1个n型连接器和20个3.5mm连接器,可在6GHz-18GHz的频段范围内高效工作。对于庞大的电源管理,我们设计了一个多功能的电源管理模块,保证整个系统的安全运行。我们终于组装好了完整的功放系统。实验结果表明,成功地实现了150W的典型输出功率。

A broadband model for Ground-Signal-Ground (GSG) pad in InP HBT technology is presented. The inductive parasitics of the structure is considered. A method to analytically extract the model parameters is proposed. For model extraction convenience, the pad is designed as structure of one-side. The model renders excellent agreement with the measured and simulated data over 1 to 325 GHz, for a pad structure manufactured in 0.5um InP HBT technology.
提出了一种基于InP HBT技术的地-信-地(GSG)发射台宽带模型。考虑了结构的感应寄生。提出了一种解析提取模型参数的方法。为了便于模型提取,垫块设计为单面结构。对于采用0.5um InP HBT技术制造的衬垫结构,该模型与1至325 GHz范围内的测量和模拟数据非常吻合。
