This paper focuses on the optics design for a 3 x 3 millimeter-wave focal plane array for the Delingha 13.7-m telescope. Three optical schemes, such as that with relay optics consisting of focusing mirrors or lenses, or that without relay optics, have been evaluated using ZEMAX, with a comparison to that from GRASP9. The conclusion drawn from the two software tools agree well with each other.

A reflectarray antenna consists of the elements of double-layer rectangular patches with slot loading of different lengths, printed on the upper- and down-surfaces of a single- layer substrate respectively, and suspended over a ground plate is proposed and designed for bandwidth enhancement. It has 15% bandwidth for -1 dB gain-drop from the peak value, is obviously wider than that of conventional reflectarray.

Applications of millimeter-wave radar, imaging and communication technology requires cost effective implementation of intelligent scanning antenna systems. This paper presents the design and measurement results of a new type nonlinear antenna array based on injection-locking theory. The required phase relation for each array element is obtained by electronic tuning through injection-locking technique, and the beam-scanning capability is demonstrated, so a shifterless beam scanning method is proposed, and an 1 X 4 element phase array verifies its feasibility.

This paper presents a novel design of an antenna with an array of slots, radiating circularly polarized conical beam. The structure of the antenna is simple and suitable for mass production. The radiation characteristics such as radiation pattern and directivity are found to be conical beam radiation, which is omni-directional in the circumferential direction. The polarization characteristics are investigated to perform the circularly polarized radiation. At the operation frequency 35 GHz, the antenna gets a circularly polarized omni-directional radiation pattern at thetas=77deg, the gain is about 1.70-5.08 dB, and the axial ratio is less than 3 dB in the azimuthal plane.

A 15 GHz coaxial Bragg reflector corrugated with sinusoidal ripples is studied by the coupled mode theory. Numerical analysis is carried out to compare with the software CST microwave studio. It is found that, although the results obtained by the coupled mode theory and the software are in agreement, both the calculation time and memories used by the coupled mode theory are much less than that needed by the software CST, and especially, the coupled mode theory is still valid for higher-order mode and higher frequency up to hundreds giga hertz, whereas the software CST needs tremendous number of mesh cells and hence can hardly process in a PC.

An all-optical frequency up-converter utilizing a four-wave mixing effect in a semiconductor optical amplifier is experimentally demonstrated. In order to characterize a spurious free dynamic range, the third-order inter-modulation distortion signal power is measured by a two-tone test. The spurious free dynamic range of the photonic frequency up-converter is 81 dB-Hz2/3 for the optical LO power of -10 dBm and the optical IF power of -16 dBm. The scheme shows a positive conversion efficiency of 5.77 dB for the optical IF power of -22 dBm and the optical LO power of-13 dBm.

The performance study of a 60 GHz band 1.25 Gbps radio-over-fiber system is presented in this paper. The bit error rate of a 60 GHz millimeter wave transmission radio-over-fiber system with and without an optical fiber under different single mode optical fiber lengths is investigated. The RF output power of the photo-detector is also presented when the tone signal (58.1 GHz, 60 GHz and 62.9 GHz) is input to the radio-over-fiber system.

The effect of LFM jamming on PRPPM-PRBC compound systemic fuze is analyzed. It is found that the correlation curve is deteriorated when LFM jamming power is larger than the anti-jamming limit of the fuze system. It is necessary to excise LFM jamming before correlation. Through the analysis of fractional Fourier transform result of LFM signal, the method of excising LFM jamming in fractal rank domain is put forward. Through simulation analysis, it is found that the method proposed can effectively excise the LFM interference and ameliorate the correlation curve.

The dot type GaAs Schottky diode shows that total resistance is 18.3 Omega, ideality factor is 1.41 at the room temperature and cut-off frequency is 435 GHz. The simulation result of designed single balanced mixer structure shows a good conversion loss of 6.28 dB.

Novel circuit model and design method for miniature LTCC UWB bandpass filter were presented. The filter prototype is simply composed with several semi-lumped elements (transmission lines and capacitors) for easy fabrication in LTCC process as size of 3.2times2.5times1.0 mm3 and half-circuit synthesis was also proposed for transmission zero and reflecting poles discussions. Two parallel capacitors added on general Chebysheve bandpass filter contributed two additional zeros to extend stop band in higher band The filter measurement agreed with the EM simulation as expected and behaves an ultra wider 3 dB bandwidth range from 3.1~10.6 GHz with the insertion loss less than 1.0 dB cross centre band and 20 dB minimum of rejection on zeros.The wider stop band in higher band also achieved due to additional two zeros contribution in novel design.
