A slot antenna configuration is proposed for UWB applications. The slot has a hybrid shape of the combination of a close-ended circle and an open-ended rectangle. The feeding structure of the slot is comprised of a 50 Ω microstrip connected to a circular patch and an open-ended patch, forming an inverted-L shape with circular corner. The antenna has a compact size of 21×26 mm2 printed on a 0.8 mm thick FR4. The measured -10dB bandwidth of the proposed antenna covers 3.03-11 GHz.

This paper presents a low power multi-channel chirp-UWB (C-UWB) transmitter for short range communication systems. The C-UWB transmitter generates a wideband FM signal with a steep spectral roll-off, while enabling a duty-cycled operation. To achieve an optimum duty-cycle control, burst-mode transmission and steep digital gradient generation techniques are employed. A 5-to-9GHz C-UWB transmitter is implemented in 65nm CMOS for multi-channel operation with a channel bandwidth of 500MHz. The transmitter achieves 1Mb/s data rate, consuming 0.5mW from a 1V supply.

In this paper, two multi-basis weighted memory polynomial models are proposed for radio frequency power amplifiers' behavioral modelling. In these models, the conventional memory polynomial function of the generalized and hybrid memory polynomial models is replaced by a weighted version of it. Experimental validation was performed on a power amplifier prototype exhibiting strong memory effects, and driven by a 20 MHz LTE signal with 1001 configuration. Proposed weighted generalized memory polynomial and hybrid memory polynomial models show superior performance when compared to their memory polynomial based conventional counterparts. Indeed, an NMSE improvement of 2 dB to 3 dB is obtained for the same complexity, and a reduction of almost 50% in the number of coefficients are achieved for the same performance.

This paper presents the design of broadband stacked microstrip antenna with E-shaped patch for digital terrestrial TV broadcasting transmission system (DTTB-TS) in UHF-band. By using the stacked structure, the E-shaped patch and the washer on the probe of the feed, the impedance bandwidth of the proposed antenna for |S11| ≤-23 dB is extended to 18.2 %. To validate the structure, an antenna operating from 544 MHz to 653 MHz was designed. The attractive feature of this design lies in the introduction of microstrip patch antenna for the DTTB-TS, which greatly reduces the cost and simplifies the structure of the digital terrestrial TV broadcasting transmission antenna (DTTB-TA), meanwhile handling high input power.

We present the design, fabrication, and characterization of two multimode waveguide-integrated terahertz (0.75-1.1 THz) resonators. Our first resonator has a size of 250μm × 125μm × 250μm, and our second resonator is a 250μm3 cube. We designed each resonator to be excited through a coupling neck of size 250μm × 10μm × 180μm in a 250μm × 125μm rectangular waveguide. We used a terahertz vector network analyzer to characterize these resonators. We deduced the resonant modes in our resonators with an electromagnetic solver. Our resonators can be used as terahertz notch filters and in klystron-like terahertz amplifiers.

A miniaturized printed antenna with dual inductor-loaded monopoles is proposed in this paper. The two monopoles contribute two adjacent resonances, which result in a broadband performance of the antenna. Each monopole is embedded with a chip inductor. The inductors introduce large inductance, which greatly decrease the resonant frequencies of the monopoles. Some important parameters are studied for better understanding of the working mechanism of the antenna. Both simulated and measured results are given, which shows the antenna is a good candidate for mobile terminals.

Two novel bandpass filters (BPFs) with the same structure but different bandwidth are presented in this paper, they are based on multilayered printed circuit boards. In this work, an H-shape coupling slot is used to realize hybrid coupling, two substrate integrated waveguide (SIW) cavities in different layers are used for resonators, and the coplanar waveguide (CPW) in input and output port is used for feeding line. Due to the size and location of coupling slots changed, the second filter has narrower bandwidth and better suppression in stopband. With the 3D environment, the proposed filters overcome the drawback of large circuit size of traditional waveguide filters, and can be effectively used for 3D Multi Chip Model (3D-MCM) in Ka band. The simulated results show that the 3dB bandwidths are 1.88 GHz (FBW=5.4%) and 0.42 GHz (FBW=1.2%) respectively, and the insertion losses at central frequency are about 1.4 dB and 4.3 dB respectively. The circuit sizes of the two filters excluding feed lines are the same, which are about 0.5λg × 0.5λg, where Ig is the guided wavelength at the central frequency.

The conventional microstrip bandpass filter has very narrow passband, and its performance is not excellently good. This paper presents a novel ultra-wideband (UWB) filter with good performance by using periodic uniplanar compact photonic bandgap (UC-PBG) cells and multi-interdigital structures. This novel filter owns a passband of 5.6GHz (1.2-6.8GHz) whose fractional bandwidth is 140%. The simulation results and measurement data verified the proposed UWB filter. In addition, the proposed UWB filter only occupies one and a half wavelength in length or 24.2 mm.
