## Abstract Wideband planar monopole antennas have recently been proposed for use on digital mobile terminals. The square planar monopole is the simplest to analyze, and suffers little degradation of radiation pattern within the impedance bandwidth. The addition of a bevel on one or both sides of t

Abstract
This paper presents a new technique to improve the impedance bandwidth of a rectangular planar monopole. The method involves beveling one part while keeping the other edges near the ground plane, which is connected to the antennaβfeeding port. The measured impedance bandwidth of the monopole can reach a ratio of 14:1 for a voltage standing wave ratio (VSWR) equal to 2:1. The measured radiation patterns of the antenna retain the typical monopole characteristics throughout the bandwidth. Β© 2005 Wiley Periodicals, Inc.

illumination on S 21 near pinch-off voltage. As the input optical power is increased, the forward gain is also increased. However, the phase of S 21 is insensitive to illumination, as is evident from Figure 4. Further, we plotted the variation in the remaining parameters (S 12 , S 22 ) with illumina
## Abstract Significant effects of groundβplane dimensions on the impedance bandwidth of a planar invertedβF antenna for a UMTS (1920β2170 MHz) mobile handset are presented. Experimental results show that, by varying the groundβplane length, the antenna studied can have an impedance bandwidth (10 d
A number of new study designs have appeared in which the exposure distribution of a case series is compared to an exposure distribution representing a complete theoretical population or distribution. These designs include the case-genotype study, the case-cross-over study, and the case-specular stud
