A novel co-linearly polarized full-duplex antenna is presented in this paper, which has a high isolation between the transmitting port and the receiving port. This antenna relies on a metal patch which is printed on a dielectric plate for radiation. To achieve a high isolation, a vertical metal wall with slot etching on it has been used. By loading this structure, the isolation between the two ports has been improved to over 30dB. The realized gain in the direction that we expected can be up to 5.5dB. This antenna can be applied to many applications,such as radars working in L-band. This antenna can also be used to construct reconfigurable antenna with PIN diodes because of its radiation characteristics.

In this letter, a broadband bandpass Wilkinson power divider (WPD) with DC block performance is introduced. The proposed topology could provide in-band equal-ripple performance of S11,S22 (S33) and S32, three transmission zeros of S11,S22 (S33) and three isolation zeros of S32 will be realized simultaneously. Owing to the existence of coupled lines and short-circuit stubs, the proposed WPD provides perfect DC isolation. Amplitudes of reflection and isolation are controlled below - 15 dB and - 20 dB, respectively. For verification, a broadband bandpass WPD with DC block performance has been simulated, fabricated, and measured. Measured and simulated results matched reasonably well.

A dual frequency filtenna (filtering antenna) for the fifth generation (5G) millimeter wave (mmWave) applications is proposed. The proposed antenna with a size of 6×6mm consists of a rectangle patch and a substrate integrated waveguide (SIW) cavity. The resonant mode in SIW cavity are TE102 (for N258 band) and hybrid TE202 mode (for N260 band). The antenna is low profile with only 0.789 mm thickness including two dielectric layers and a bounding layer. The introduction of round and rectangle slots enhanced the frequency filterability. The operating frequency band is from 24.61 GHz to 27.74 GHz and 39.50 GHz to 42.15 GHz, almost covering 5G N258 (24.25-27.5 GHz) and N260 (37–40 GHz) mmWave bands with reflection coefficient less than -10 dB. The average gain in passband is 4.5 dBi and 1.6 dBi and the relative impedance bandwidth is 11.96% and 6.49%, respectively. The merits make the proposed dual frequency filtenna a good candidate for 5G mmWave applications.

The combination of digital predistortion (DPD) techniques and crest factor reduction (CFR) techniques can simultaneously meet the linearity and efficiency requirements for power amplifiers (PA) in future high-speed wireless communication systems, and therefore has received wide attention. This paper propose a novel in-band and out-band combination (IOC) technology that process the in-band and out-band parts of the predistorted signal separately to reduce the impact of CFR on DPD. The simulation results show that the IOC technology can reduce unnecessary peak clipping and greatly improve the linearization performance.

A dual-port rectenna designed for simultaneous wireless information and power transfer is proposed in this paper. The antenna is a printed structure in the form of a patch, and the structure consists of a patch and a dipole arm. The antenna realize function of simultaneous data communication and energy harvesting through two ports. The antenna collects energy at 1.95GHz and communicates data at 2.4GHz. In both operating frequency bands, the coupling of the two ports is low. Compared with the traditional rectenna, the antenna combines communication and energy harvesting functions, which can reduce the size of the antenna and is more suitable for use in some devices for internet of things.

In this paper, a high-gain sinuous antenna is proposed for 1–10 GHz applications, which is mainly composed of a planar sinuous antenna, a cone-shaped reflective backplate and a dielectric lens. The operation mechanism of the ultra-wideband lens antenna is analyzed in detail. The simulated and measured results demonstrate that the VSWR of the antenna is less than 2 in the whole operation band, and the maximum gain approaches 12 dB.
