In Japan, ultra-high-deflnition television (UHDTV) satellite broadcasting will be launched in the 12-GHz band in 2018. An intermediate frequency (IF) band of 1.0 to 3.2 GHz is used in the receiving systems for 12-GHz-band satellite broadcasting. In view of frequency sharing with other services that use the same frequency band, it is important to suppress emission of radio waves that leak from the components of receiving systems. However, it is difficult to measure the low-level emission power of leaked radio waves that are wideband-modulated. In this paper, we propose a system for measuring low-level and wide-band modulated power by using direction of arrival (DOA) estimation and a correlation between a receiving signal and a leaked radio wave. From the results of evaluating our proposed system, it is shown that the accuracy of the estimated arrival angle and the measured power were less than 0.3 degrees and 1.8 dB, respectively.

We study the performance of a MIMO communications system that uses electrically-small biomimetic antenna arrays (BMAAs). We show that MIMO systems using BMAAs can outperform those that use conventional antenna arrays with the same aperture sizes. This is shown to be due to the efficient extraction of the maximum available power from all linearly-independent modes of excitation of the array, which results in the natural decoupling of the elements. As a proof of concept demonstration, we examine the use of a two-element BMAA consisting of two λ/4 monopole antennas as part of a MIMO communication system. The capacity that can be achieved from a MIMO system using this antenna is compared with the capacity obtained if the MIMO system uses a conventional antenna array with the same aperture dimensions. This is done through computer simulations by designing prototypes of both antennas and using them in an emulated MIMO communications systems. These results demonstrate that using the BMAA in the MIMO system results in considerable capacity enhancement.

A compact ultra-wideband (UWB) antenna with triple wideband-notched characteristic is presented. The three notched wide bands are respectively obtained by loading U-shape slot, L-shape stubs, and nested semielliptical slots on the ground plane with a rectangular slot and a hexagon patch, which is fed by a coplanar waveguide (CPW). The simulated results show that the antenna achieves the 10dB impedance band from 2.7 to 10.7 GHz in which three notched wide bands of 3.3∼3.8 GHz, 4.75∼5.9 GHz, and 7.25∼8.4 GHz for return loss (RL) less than 10 dB are obtained. The z-direction gains of the antenna at the operating frequencies of 3.1, 6.7, 9 GHz are larger than 2.7, 2, 4.4 dBi, respectively. While the z-direction gains of the typical frequencies of 3.4, 5.2, 7.8 GHz in the three notched bands are −7.5, −6, −9dBi, separately. The surface current distributions at the operating frequencies and the typical notched frequencies are presented for verifying the design method and principle of the antenna. Consequently, the mutual interference between the narrowband systems of WiMAX/WLAN/5G/X-band satellite communication and UWB communication system can be reduced significantly. Moreover, the design has the smaller size of 26×25 mm2, compared with existing triple band-notched UWB antennas. Therefore, the antenna is very promising for modern UWB communication applications.

Utilizing the transmission /reflection measurement method, we investigated the complex conductivity of conductive ink films at microwave X-band. The results show that the frequency dependence of the complex conductivity is in good agreement with the Drude model. However, the retrieved plasmon frequency ωp and the collision frequency Wt are much lower than those of metal materials. The effect of surface morphology of the films on complex conductivity was investigated. The study provides a solid foundation for the applications of conductive ink films, such as wideband absorber designs.

Conceptual design of planar wide beam circularly polarized (CP) antennas with end fire radiation is proposed. The fan-shaped magnetic dipole of 270° and a V-shape open loop is employed to achieve a wide 3-dB AR beam width within the whole elevation plane. Then, quantitative relation between the thickness of the open loop and the value of δ (which means leading phase between the different arms of the loop) is accomplished and the fitted equation is also presented. According to this, preliminary design of antenna is accomplished. The modeling simulation results eventually verified the antenna design approach.

This paper presents a simple and efficient method for the design of a frequency tunable self-diplexed antenna based on loading asymmetric grounding-vias. The structure consists of two antenna elements loaded with two asymmetric grounding-vias, specifying the uplink and downlink operation frequencies. By choosing the appropriate positions of the two grounding-vias, high isolation between the two antennas can be achieved. Results verify the multi-functionalities of the proposed compact structure in terms of frequency-tunability, high isolation and low cross-polarization discrimination.

In this paper, a frequency selective polarization conversion metasurface is designed based on E-shaped high permittivity ceramics. A frequency selective polarization conversion is realized in 10.95GHz∼12.069GHz. Two magnetic resonances are generated, which lead to the cross-polarization reflection. The simulated results show that the maximum conversion efficiency is nearly 100% at the two resonant frequencies. In this paper, high permittivity ceramic material is used to design all-dielectric metasurface in microwave band. As an alternative method to design frequency selective polarization conversion metasurface, high permittivity ceramics provide potential applications in high temperature or high power.

This work reports our recent progress in 3D thermoacoustic imaging based on compressive sensing. Thermoacoustic imaging has been extensively research in the past 15 years and has developed numerous applications especially in biomedical engineering. Pursuing a fast data measurement in the experimental process of thermoacoustic imaging is very meaningful. Compressive sensing based 3D thermoacoustic imaging technique holds great promise to achieve this goal. Detailed procedure of the novel method is introduced. Simulation results show that only 10 measurements are enough to obtain a good thermoacoustic image of four spherical objects.

A compact broadband circularly polarized (CP) antenna over the artificial ground structure (AGS) is investigated. The CP radiation patch is comprised of a truncated corner square patch loaded by an extended strip. The AGS which is comprised of a 4 × 4 slot-loaded square metal patches changes the reflection phase in accordance with the polarization state of the incident wave. Broad bandwidth including impedance bandwidth, 3-dB axial ratio (AR) bandwidth, and gain bandwidth is achieved by properly combining the transmitted wave from the patch antenna and the reflected wave from the AGS. The measured results show that the AR bandwidth of the antenna is 14.0% (2.84–3.26 GHz), while the impedance bandwidth is 41.3% (2.48–3.72 GHz). The antenna gain at boresight is 5.35 dBic at 2.9 GHz. The gain fluctuation is less than 1 dB in the whole operating bandwidth. The overall antenna volume is 0.40 × 0.40 × 0.048λ0 at 3 GHz.

A sparse Bayesian learning (SBL) based method with a novel grid deriving strategy is proposed in this paper for joint direction of departure (DOD) and direction of arrival (DOA) estimation in bistatic MIMO radars. Directly applying compressed sensing methods to MIMO radars leads to a heavy computational load because of high dimensional matrix operations. To solve this problem and improve the estimation accuracy, we first construct a coarse grid with some proper initializations, and then resorts to an off-grid SBL model to handle the off-grid gap, where an expectation-maximization (EM) algorithm is utilized iteratively for grid refining aiming to narrow the gap between the true and the estimated DOD and DOA. Simulation results verify the efficiency of the proposed method.
