—In this paper, we propose a method to use 1-D dielectric slabs, instead of metallic Frequency Selective Surfaces (FSSs), to produce Partially Reflective Surfaces (PRSs) with positive reflection phase gradients. The structure is realized by a single kind of dielectric substrate. It is modeled as cascaded transmission lines and then analyzed by virtue of the(More)
An L-Sloted Dual-Band microstrip antenna for WiMAX 3.5G/5.8G applications is demonstrated in this paper. A prototype has been designed, fabricated and tested. The measured results show that the operating frequencies of the antenna are 3.45–3.65GHz and 5.6–5.9GHz for an S-Parameter of better than −10 dB. Satisfactory radiation patterns(More)
In this historical cohort study, 236 patients with primary rheumatoid arthritis were treated with the tumor necrosis factor inhibitors, etanercept or infliximab (n = 80), or by conventional methods (n = 156). Results revealed that 11 patients developed varying types of peripheral neuropathy at 1-2 years post-treatment (mean 16 months). The incidence of(More)
