In this paper, a new dielectric resonator antenna (DRA) is designed for WLAN applications, where a simple Mshaped dielectric resonator (DR) is excited by a conformal patch connected to a microstrip line. The simulation process was done by using computer simulation Technology (CST) Microwave studio suite 2010.The simulated results show that the proposed DRA achieves an impedance bandwidth of about 31.32% for VSWR ≤ 2, covering a frequency range from 4.63 GHz to 6.35 GHz. The antenna also provides a gain range of 5.64-7.34 dB across the operating bandwidth. The proposed antenna is suitable for wireless local area networks (WLAN 5.15-5.30GHz) (IEEE 802.11a). It has also application in highperformance radio LAN (HIPERLAN) which operates across 5.15 to 5.30 GHz. Keywords-Dielectric Resonator Antenna (DRA), square patch feed, CST Microwave Studio suite 2010, WLAN.
Bardet–Biedl syndrome (BBS) is a rare disorder with a frequency of 1:1,60,000. The disease is inherited in an autosomal recessive manner. Less than 15 cases have been reported from India. We present a case of Bardet–Biedl syndrome presenting to the medical emergency with acute breathlessness because of de-compensated renal failure and salient features such as marked polydactyly, central obesity, retinitis pigmentosa, end-stage renal diseases, and mental retardation. Genetic study showed that the patient had BBS genetic variant 9 (MIM#615896), VUS variant. The patient was primarily treated for end-stage chronic renal failure with hemodialysis. We are reporting this case for its rarity and the presence of a novel genetic variant of an unidentified significance as per genome mapping. BBS is often not diagnosed at all or diagnosed late until end-stage renal failure sets in. Timely diagnosis might not help treat the condition but surely improve the quality of life for the patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
