This paper presents a novel dual slant polarized antenna for millimeter-wave (mmWave) base stations. Compared with the traditional slant polarized mmWave antennas, the proposed antenna offers the advantages of high cross-polarization discrimination (XPD), good aperture efficiency, simple structure, and low profile. The corner-fed substrate integrated waveguide (SIW) cavity is adopted to improve the port isolation and XPD of this slot-coupled antenna. Four corner-truncated patches connected by a thin cross strip are placed over the SIW cavity to increase the operation bandwidth. Then, a 2 × 8 antenna array is designed to exemplify the antenna element performance. To improve impedance matching, a shorted patch is introduced in designing the series feeding network and the power divider. The experimental results show that the 2-dB-down gain bandwidth of the proposed antenna array reaches 6.0% and the port isolation is better than 20 dB. The gain and XPD of the antenna array measure 16.7 dBi and 25 dB at the center frequency, respectively.

In this paper, a method for substrate permittivity and loss tangent characterization applicable for frequencies in the subterahertz range is presented. Planar transmission lines fabricated on three different printed circuit board (PCB) materials and four different on-chip/on-wafer materials are being used for measurement along with a wafer probing station equipped with on-wafer probes and frequency extenders. A comprehensive procedure for calculation of substrate permittivity, total loss, characteristic impedance, and dielectric loss tangent is presented. Measurement data up to 67 GHz is given in case of PCB and up to 500 GHz in case of on-chip/on-wafer materials and compared against reference data and competitive materials from recent publications.

“…However, the traditional resonator methods based on rectangular substrate integrated waveguide (RSIW) resonators suffer from single frequency or narrowband applications. For example, the frequency bandwidth must meet the limitation that: f H /f L < 2.12 [18]- [21]. To extract wideband material characteristics, a large number of cavities, which are designed to resonant at different frequencies, have to be used in the experiment.…”

In order to accurately design microwave, millimeter-wave components and circuits, a simple and accurate method for extracting extremely wideband characteristics of the printed circuit board (PCB), including relative dielectric constant, dielectric loss tangent, and equivalent copper conductivity, is proposed and validated in this paper. By properly selecting wideband distribution of multiple TM mn0 modes in the designed circular substrate integrated waveguide (CSIW) cavities, extremely broadband properties of PCB can theoretically be extracted with only one pair of CSIW cavities. The proposed method overcomes the limitations of conventional methods that only support narrowband applications, require a large number of cavities, and have relatively large errors. The experiments show that the proposed method is able to extract, accurately and efficiently, 8-110 GHz characteristics of a TLY-5Z substrate-based PCB and the extracted results are verified by designing and measuring the fourth-order Chebyshev filter at X-band. INDEX TERMS Dielectric constant, dielectric loss tangent, equivalent conductivity, circular substrate integrated waveguide (CSIW) cavity, wideband characteristics.
