Abstract-In this work, a millimeter wave microstrip frequency-mixer design based on graphene is presented. The desired frequency mixing behavior is obtained using a nonlinear component consisting in a microstrip line gap covered by a graphene layer. The circuit includes microstrip filters that have been designed to obtain a high isolation between the input and output ports. The nonlinear behavior of the frequency mixer has been experimentally evaluated in the 38.6-40 GHz input signal frequency range, for different values of the input power and local oscillator power.

“…A good match from 56 to 66.5 GHz can be seen from the simulated |S 11 | profile, which even leaves some tolerance margin against the target bandwidth. An excellent match from 55.5 to 65 GHz can be seen from the measured |S 11 | profile, which clearly demonstrates that the antenna has a sufficient bandwidth for the 60-GHz radios [23]. Figure 11 shows the complex input impedance of the antenna.…”

Abstract-This paper presents the development of a standard surface mountable ceramic ball grid array (CBGA) package with an integrated patch antenna in low temperature cofired ceramic (LTCC) technology for emerging single-chip 60-GHz radios. It addresses the challenges of low-loss wire bonding interconnections required between the chip and the antenna as well as the package to allow efficient utilization of available space for miniaturization. The compact package of size 12.5×8×1.265 mm 3 achieves good electrical performance. For instance, the package part exhibits insertion loss < 0.08 dB, return loss > 22 dB, and attenuation rate < 0.2 dB/cm below 5 GHz; while the antenna part demonstrates 8-GHz impedance bandwidth and 8 ± 2 dBi peak realized gain at 60 GHz. Simulated and measured results are compared. They agree reasonably well, indicating the feasibility of designing and manufacturing the integrated antenna package in LTCC for millimeterwave applications.

“…For the refractive SLA, an extended hemispherical lens (EHL) is considered, and its refractive index is 3.4205 (Si) [1,2]. After careful calculation and comparison, the resolution of the imaging system with the SLA is chosen as 0.25 • ; the diameter of the EHL is chosen as 0.86 mm; and the corresponding extended length is 0.13 mm.…”

In this paper, a binary diffractive small lens array (SLA), based on binary optical ideas, is introduced and designed for THz imaging. Compared with common refractive SLA, the designed binary diffractive SLA is easier to fabricate and has more design freedom. A hybrid numerical method, combining geometrical optics/physical optics (GO/PO) and two-dimension finite-difference time-domain (2D-FDTD), is adopted to design and analyze the THz imaging system, which is composed of an optimized objective lens and binary diffractive SLA. The numerical results show that, in the conditions of lower bandwidth requirements, the seven-step diffractive SLA can be considered a good substitute for the common refractive SLA. The numerical method has also been verified by the relative experimental results.
