This paper presents the design of a V-band hybrid integrated high-gain antenna. This antenna is designed to meet the system-on-chip applications in a quad flat no-lead (QFN) package. The antenna consists of an on-chip loop radiator, a dielectric resonator (DR), and an off-chip ground plane. The on-chip radiator is fabricated to excite the DR using the standard 0.18-$\mu \text{m}$ CMOS technology...
In this paper, a miniaturized frequency selective surface (FSS) composed of convoluted element of dipoles is proposed. The FSS is printed on one face of a single-layer substrate with a relative permittivity of 2.65. The novel FSS has promising miniaturization characteristics with the unit cell dimension 0.042λ×0.042λ, where λ represents the free-space wavelength corresponding to the resonant frequency...
In this paper, we take the typical LCCC electronic package structure as the research object, which is under the load of temperature cycle, and evaluate the thermal fatigue life of its solder joint based on the strain fatigue model and finite element method (FEM), and then predict its thermal fatigue life by using the engineering algorithm of electronic package structure. The results show that the...
In order to reveal the transformation of heavy metals in rice-crab ecosystems and to maintain the sustainable development of crab industry, it is important for evaluating the environmental quality of rice-crab production base of the Liao River Delta. Therefore, the contents of heavy metals in water, soil and aquatic plants of the rice-crab production base in the Liao River Delta were monitored from...
