“…The corresponding structure is an asymmetric SIW waveguide shown in Figure 1(b) named half‐mode substrate integrated waveguide (HMSIW) [11]. This guide is equivalent to a structure of the microstrip line with short‐circuited edge [12] illustrated in Figure 1(c). A novel configuration of a SIW waveguide using corrugated microstrip stubs pattern on the edges of the waveguide instead the via‐holes was proposed in [13] and shown in Figure 1(d).…”

BACKGROUND: This study assessed BRCA1 and BRCA2 mutation prevalence in an unselected cohort of patients with triple-negative breast cancer (BC). METHODS: One hundred ninety-nine patients were enrolled. Triple negativity was defined as <1% estrogen and progesterone staining by immunohistochemistry and HER-2/neu not overexpressed by fluorescence in situ hybridization. Having given consent, patients had BRCA1 and BRCA2 full sequencing and large rearrangement analysis. Mutation prevalence was assessed among the triple-negative BC patients and the subset of patients without a family history of breast/ovarian cancer. Independent pathological review was completed on 50 patients. RESULTS: Twenty-one deleterious BRCA mutations were identified-13 in BRCA1 and 8 in BRCA2 (prevalence, 10.6%). In 153 patients (76.9%) without significant family history (first-degree or second-degree relatives with BC aged <50 years or ovarian cancer at any age), 8 (5.2%) mutations were found. By using prior National Comprehensive Cancer Network (NCCN) guidelines recommending testing for triple-negative BC patients aged <45 years, 4 of 21 mutations (19%) would have been missed. Two of 21 mutations (10%) would have been missed using updated NCCN guidelines recommending testing for triple-negative BC patients aged <60 years. CONCLUSIONS: The observed mutation rate was significantly higher (P ¼ .0005) than expected based on previously established prevalence tables among patients unselected for pathology. BRCA1 mutation prevalence was lower, and BRCA2 mutation prevalence was higher, than previously described. Additional mutation carriers would have met new NCCN testing guidelines, underscoring the value of the updated criteria. Study data suggest that by increasing the age limit to 65 years, all carriers would have been identified. Cancer 2012;118:2787-

“…The last filter DGS structure serves as quarterwave backshort of the MSL to uFIN transition. The 3r d harmonic signal of the Y -band multiplier propagates along the HE I waveguide [2], which acts as a highpass filter (HPF), to the WR-4 longitudinal E-field probe transition. The milled channels of the planar circuits ensure mono mode operation across the full D-band and 170 GHz to 250 GHz (part of Y band).…”

To extend the frequency range of existing short-range radar modules for industrial applications, millimeter-wave frequency multipliers based on cost-effective PCB technology are required. This paper describes a zero-bias D-band frequency doubler and Y -band frequency tripler based on pure PTFE material and the commercially available DBES105a diode from United Monolithic Semiconductors (UMS). At an input drive level range of 16 dBm to 18 dBm the multipliers deliver output power levels POUT E [5, -5] dBm from 100 GHz to 160 GHz and POUT E [-11, -20] dBm from 180 GHz to 230 GHz.

“…As a result, these methods might lead to fabrication problems and also require large PCB sizes [1]. Recently, some new HPFs using various physical structures and design methods have been reported successively [2][3][4][5][6][7][8][9][10]. A new approach to designing a maximally flat Butterworth HPF, which transforms an open-circuited series stub to short-circuited shunt stub, has been extensively investigated in [2].…”

“…A 6th-order pseudo HPF using balanced double-sided parallel-strip lines, for which the width of the dielectric layer is equal to the width of the conducting strips, has been described in detail in [4]. A concept of very simple planar HPFs using a microstrip with a short-circuited edge has been extended to the millimeter-wave filters with passbands beginning in the K and Ka bands, which has been reported in [5]. In [6][7][8], the complementary split ring resonator (CSRR) is used to design and implement the various HPFs.…”

Abstract-A novel and compact highpass filter (HPF) is proposed in this article. This filter is based on a hybrid-coupled dual-metal-plane microstrip/DGS (defected ground structure) on a single-layer substrate. The resonator etched in the grounding plane shows a wide-band dual-mode resonant response within the desired high-pass frequency band, and is composed of a modified U-shaped slot resonator embedded with an L-shaped slot. The wideband highpass filtering performance is achieved by the dual-mode resonator at the bottom of single-layer substrate coupled broadside to the top microstrip stubs. Simulated results from the electromagnetic (EM) analysis software and measured results from a vector network analyzer (VNA) show a good agreement, and an excellent performance with nearly 40 dB attenuation at the lower stopband has also been obtained across an ultra-wide highpass range. A designed and fabricated prototype filter, having a 3-dB cutoff frequency (f c ) of 5.9 GHz, shows an ultra-wide highpass range, i.e., from 5.9 to 15.52 GHz, and exhibits the highest pass-band frequency up to 2.6f c . The printed circuit board (PCB) area of the implemented filter is approximately 0.086 λ g × 0.13λ g , λ g being the guided wavelength at f c .
