Decoupling of a wideband circularly polarized (CP) conformal array is studied by single-negative (SNG) metamaterial (MTM) isolator. The consists two CP antennas, which are assembled on an arched carrier, and SNG structure placed between the antenna elements for coupling reduction. four wheel-shaped units concentrically. bianisotropic, its constitutive parameters tailored to form wide isolation band. By using proposed structure, mutual reduced up 25 dB at 4.5 GHz, improved in 3.9-5.05 GHz In...
A dual-band gyrotron traveling wave amplifier (Gyro-TWT) can reduce the size, cost, and weight of a transmitter in radar communication systems. In this paper, dual-mode input coupler for K/Ka is designed. This structure composed two different types couplers, one coaxial Ka-band TE2,1 Gyro-TWT other Y-type K-band TE1,1 Gyro-TWT. For reducing backward mode reflecting into to influence operating bandwidth, Bragg reflector with strong selective characteristic inserted between these which make...
The previously proposed resonance-based reflector (RBR) antennas have the merits of wide impedance bandwidth, low-profile, and unidirectional pattern; however, their front-to-back ratio (FBR) bandwidths are narrow. In this paper, a wideband RBR is for FBR bandwidth enhancing antenna with low profile. consists metallic ring three stubs printed on substrate. It has ±90° in-phase 63.57% (3.23-6.24 GHz) its reflection magnitude values range from -0.02 to -11.5 dB within band (-90° <; φ 90°)....
The gap plasmon resonance can generate a local enhanced electric field and make the electromagnetic energy mostly confined in microfluidic, thereby increasing interaction between detection sample terahertz wave.

Simulation results show that this new design can reduce dimensions by 25% compared conventional M-shaped structure capacitance-loaded.
This paper presents a dual-band broadband circularly polarized antenna applied to Chinese Compass Navigation Satellite System (COMPASS). It is based on the study of ring and combined with eigenmode theory analysis, frequency band broadened complex feed networkby simplified by using stacked circular polarization characteristics can be achieved in both bands. The measured impedance bandwidth this 1.195-1.235GHz 1.495-1.665GHz, maximum in-band gain 6.6dB, which two civil signals B1c B2b COMPASS.
A novel compact ridge waveguide band-stop filter with harmonic suppression is presented in this paper. The composed of a waveguide, and some stagger-placed tuning screws. To validate the structure, an order-3 designed, simulated optimized as example. stop-band 18-20GHz pass-band frequency range 8-12 GHz. In addition, we have designed order-11 to demonstrate bandwidth can be improved by increasing number orders.
