“…[16] used the co-design to simultaneously optimize the avionics characteristics and the control of an earth observation satellite, finding that the optimized controller and avionics could meet the challenging requirements. [17] adopted the co-design strategy to optimize the filtering antenna of the modern wireless communication systems, based on which a novel two-layer filtering antenna is proposed. [18] employed the nested strategy to perform the co-design of the multi-motor driving system and corresponding experimental results demonstrated the efficacy of the nested co-design.…”

Design optimization of structure and control combined systems are coupled problems. The conventional sequential design strategy (structure design sequentially followed by control design) usually neglects the coupling effects between structure and control and can only produce sub-optimal designs of the complex systems. Nevertheless, simultaneous design strategy with a reasonable and explicit optimization iteration management can ensure global optimization designs of the coupled system. In this study, a surrogate based co-design is explored to achieve the simultaneous optimization, which transforms continuous optimal control problems into discrete nonlinear programming problems. The discrete control parameters combining with the structure parameters can be simultaneously optimized and the co-design strategy can be achieved by introducing necessary and reasonable dynamic constraints. Here, the proposed surrogate based co-design is tested using a practical engineering case study, a heavy-load face-shovel excavator (FSE). The case study is built upon existing FSE design problems by incorporating detailed structure and control design variables while satisfying the system dynamic equations. The proposed surrogate based co-design is implemented and compared with the conventional sequential design strategy and an existing co-design strategy. Results indicate that the surrogate based co-design is accurate and efficient enough to achieve better performances than the conventional sequential design strategy by making FSE's structure more compact with relatively small vibrations.

“…6,7 Owing to effective and efficient use of transceiving signals in various positions, omnidirectional radiators are widely utilized in various types of communication devices. 8 At present, the techniques for implementing the filtering radiators are generally divided into two categories, one is to load the filters on the feedline, and the other is integrating the filter and radiator. Adding a filter to the feedline of the antenna is an effective way, however, it requires additional electronics components (diodes, conducting stripline) and biasing circuits, remains challenging to integrate along with the existing print planar circuits and switching to other operating band requiring additional matching networks.…”

This article presents a printed planar lowpass filtering monopole antenna with wide stopband for automotive communications. This monopole radiator exhibits hybrid geometry and is constructed using a circular slot and corner edged slot. The fundamental radiator's ground plane is defected to enhance the VSWR bandwidth and four rectangular patches with two open-circuit stubs is being used to construct a lowpass filter with wide stopband. The filtering characteristics are further improved by incorporating circular complementary splitring resonator (CCSRR) on the ground plane. The proposed lowpass filtering antenna is obtained by integrating the lowpass filter with a super wideband (SWB) monopole antenna and experimentally validated with the measured reflection coefficient as <−10 dB in 0.67 to 4.15 GHz (69.25%). In this operating spectrum, the radiation pattern characteristics of the filtering antenna is identically stable and the passband average gain is >4.45 dBi. Further, the prototype filtering antenna bandwidth and radiation characteristics are analyzed in housing effects. The filtering antenna can be conveniently printed along with the existing printed circuit board or it can be located inside the shark fin housing thereby eliminating the need for a dedicated location in vehicular communications.

“…The main and most common technique is to combine the radiated element as the filter's last order resonator or called synthesis approach. The cascading mismatch of filters and antennas may be minimized by air coupling instead of direct coupling between elements [14][15][16][17][18][19][20][21][22]. The filtering antennas feature small loss and compact volume with no extra circuits to match the impedance.…”

This paper proposes and demonstrates a compact integrated filtering antenna built on a square ring resonator coupled with a capacitors loaded microstrip line filter. A microstrip filter module is connected to feeding line of the conventional patch without adding extra space. Thus, the combined configuration possesses radiating and filtering functions simultaneously. The proposed filtenna has a fractional bandwidth (FBW) of 3% at center frequency 2.4 GHz with 2.5 dB of maximum gain. The obtained result shows that the proposed design shows good stopband gain rejection, good selectivity at band edges, and smooth passband gain. Furthermore, the introduced filtenna has advantages of a small size and a simple structure, which makes it ideal for interconnection with different wearable devices operating within 2.4 GHz wireless system range.
