## Abstract The use of an asymmetrical feed probe is shown to significantly increase the impedance bandwidth of a square planar monopole antenna. The feed probe is offset from the center of the planar element. The optimum location of the feed probe is shown to increase the impedance bandwidth by a

β¦ Synopsis
This paper describes a printed rectangular-plate monopole fed by microstrip line. The effect of varying the plate width, feedgap height, and feedline width on the impedance bandwidth is examined. It is shown that for a fixed ground-plane size, that optimization of these parameters can yield an impedance bandwidth ratio of 4.3:1, without using any broadbanding techniques.

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 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 article presents the comparative study of impedance bandwidth of rectangular microstrip antenna comprising different shaped slots on the patch. It is found that the rectangular slot on the center of patch is effective for the enhancement of impedance bandwidth in comparison with el
## Abstract Printed antennas are very popular for commercial and military RF (radio frequency)/microwave communication systems because there is an enormous evolution in printed circuit technology. In this study, printed monopole and filamentary excited dipole, which are basic models and easily appl
## 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
