A novel wideband balanced filter based on modified coupled lines structures is proposed. The presented modified coupled lines structures are implemented by loading open/ shorted stubs at the end of the traditional open coupled lines to perform bandpass and bandstop response. To obtain the high selectivity and good out-of-band suppression for the differential mode, four full-wavelength open stubs are introduced to achieve multiple transmission zeros and further improve the suppression level over a wide frequency band due to the all-stop transmission characteristic for the common mode. A prototype with 3-dB fractional bandwidth of 38% for the differential mode is designed and fabricated for demonstration.

A novel rectenna based on the grid-array antenna is presented in this paper. The grid-array antenna provides the feasibility to tilt the radiation beam. Two isolated feed points are designed in the grid-array antenna so as to generate two different beams separately. In this way, the rectenna can harvest more wireless RF energy from different directions. Finally, a prototype is fabricated and measured. Under the power density of 1 μW/cm2, it can produce over 50 μW dc power when the incident angle of incoming wave ranges from −10° to 10° at the E-plane.

This paper implements a time-interleaved ADC (TI-ADC) system with embedded 16GHz wideband track-hold (T/H) front-end. The TI-ADC is characterized with 32GS/s total sampling rate, by time-interleaving 16-channel sub-ADCs with 2GS/s individual sampling rate and 8-bit resolution. A digital blind post-calibration technique based on frequency domain analysis of the TI-ADC output is proposed, which is characterized using a comprehensive TI-ADC behavioral model. The model takes into account the timing, gain and offset mismatch errors. All the three mismatch errors are characterized using the specific basis functions. Without the need of training sequence, a blind calibration model is developed during an iterative loop to extract the mismatch errors, which are subtracted from the measured TI-ADC output successively. A maximum of 3-bit improvement for the effective number of bit (ENOB) has been achieved, resulting in a 6.5 bit ENOB at low-end frequency and 4.5 bit ENOB at high-end frequency. Further, the proposed technique is also effective to wideband signal's sampling.

A novel polarization rotation technique based on an artificial magnetic conductor (AMC) structure is proposed. A new polarization-rotation AMC (PRAMC) with a height of only 0.04 λ0 is designed and a large polarization rotation bandwidth of 29.1% can be achieved. Firstly, the PRAMC is applied to design a low-profile circularly polarized dipole antenna with a broad axial ratio bandwidth and beamwidth. In addition, combining a PRAMC-based multi-polarized dipole antenna with a switch network, a novel polarization-reconfigurable antenna is achieved, in which three polarization states of right-handed, left-handed circular polarization (RHCP, LHCP) and +45° linear polarization (LP) can be realized by controlling the dc bias of the switches accordingly. Moreover, a new active corner-cut PRAMC loading with several varactors is proposed to achieve a novel frequency- and polarization-reconfigurable dipole antenna for applications in multi-function wireless communication systems.

Balanced/balanced-to-single-ended networks have been used widely in modern communication systems due to their ability of easy connection in balanced systems as well as differential-mode power division, common-mode suppression. Furthermore, filtering balanced or balanced-to-single-ended networks have become increasingly of interest for the advantages of multiple functions and compactness. In this paper, the filtering balanced-to-single-ended power dividers and the balanced branch-line couplers realized by replacing the transmission line structures with filtering structures are reviewed and discussed.

A dual-mode bandpass filter with compact size is proposed by using a new type of rotational symmetric dual-mode rectangular resonator. Due to the feed structure, two transmission zeros are generated near the lower and upper passbands to improve the skirt-selectivity of the filter. By adjusting the mutual coupling between the loading meander-line loop resonators, one transmission pole and neighboring transmission zero can be controlled. Two capacitors are added between each meander-line loop resonator and feedline to improve in-band performance. Based on this topology, a compact filter for GPS/Compass (BeiDou)/GLONASS applications has been designed, analyzed and fabricated. Measured results verified the validity of this design methodology. This proposed filter exhibits the small size of 0.11 λg×0.10 λg.

In this paper, we propose a multi-band impulse detection technique to improve the detection of small objects. The choice of frequency bands is based on millimeter ultra-wideband (UWB) normalization and is related to the radar cross section of the objects to be detected. A nomadic impulse architecture associated with the detection principle is proposed. By using two orthogonal polarizations, our results show that multi-band impulse method offers better performances in terms of continuous detection surface compared to conventional single band detection system.

Stub-loaded ring resonator and its application to miniaturized wideband BPF are presented in the paper. Detail analysis shows that the presented stub-loaded ring resonator can allocate three resonant modes within the desired frequency range, and due to the dual path effect of the ring resonator, two transmission zeros can be introduced at the upper and lower cut-off frequencies, resulting high passband selectivity. A tri-mode wideband BPF is simulated, fabricated, and measured. The EM simulated and measured results are presented, and an excellent agreement is obtained.
