A pearl millet inbred germplasm association panel (PMiGAP) comprising 250 inbred lines, representative of cultivated germplasm from Africa and Asia, elite improved open-pollinated cultivars, hybrid parental inbreds and inbred mapping population parents, was recently established. This study presents the first report of genetic diversity in PMiGAP and its(More)
Earlier, we established that a major drought tolerance QTL on linkage group 2 of pearl millet is also associated with reduced salt uptake and enhanced growth under salt stress. Present study was undertaken to re-assess the performance of drought tolerant (PRLT 2/89-33) and drought sensitive (H 77/833-2) parents along with two QTL-NILs (ICMR 01029 and ICMR(More)
—In this communication, a new compact UWB monopole antenna with dual band rejection is presented. The antenna is designed using FR4 substrate with dielectric constant 4.4, loss tangent 0.02 and a height of 1.59 mm. Initially the UWB antenna is designed to obtain a 153% fractional bandwidth from 2.4 GHz–21.7 GHz. The ground plane beneath the patch is etched(More)
—In this paper, a compact, planar ultrawideband (UWB) monopole microstrip antenna is proposed which offers dual band notch characteristics with enhanced rejection at frequency bands centered at 3.4 GHz and 5.5 GHz. To realize enhanced band notched characteristics at 3.4 GHz, a pair of filters is incorporated which includes an inverted 'L' shaped slot and a(More)
This paper presents analysis of non-focal Rotman lens antenna design. A ten beam prototype feeding an 20-element antenna array working in ISM band has been simulated using RLD v1. 7 software. Simulation results show that the designed lens shows good performance in the operating frequency band of 2. 4Ghz showing a return loss of-17db.
