An ultra-wide band planar monopole antenna is presented in this paper. This antenna uses a pentagonal patch as radiation unit and is fed by a microstrip line. The relevant simulation is performed by using Ansoft HFSS. The return loss curve and the radiation patterns of this new antenna are given. And the effect of the size of the various parts of the antenna on the reflection loss is analyzed. Experimental results show that the proposed antenna provides an ultra-wide bandwidth (1.70~12.90 GHz) for return loss less than -10dB (VSWR<2). It is suitable for current ultra-wide band communication systems.

This article deals with the various designs of a novel compact microstrip fed UWB antenna to investigate the corresponding return losses of different structures. The dimension of the designed antenna is 33 x 19 x 1.9 mm3 with FR4 substrate and it can be operated from 2.846 - 11.7458 GHz. The effects of varying the structure of antenna are to exhibit the investigation of corresponding return losses. Different structures of antenna are simulated in Ansoft HFSS simulator. The results of return losses and radiation patterns are explored with the ultra wide band (UWB) rectangular Stair slot antenna. The modified structure of antenna shows the minimized return loss with an enhanced bandwidth that satisfies good UWB characteristics. Antenna performance can also be explored from the radiation behavior of the antenna which is relatively omni-directional pattern for rectangular Stair slot antenna

This paper presents a wideband polarized antenna that is designed and analyzed for the cellular communication applications. The proposed antenna is designed with the coplanar wave guide feeding (CPW) by using the RT/ duroid 5880 material with a dielectric constant 2.2. It is observed that in the proposed model the return loss is -21.40dB for ungrounded CPW where as for the grounded CPW the loss is reduced to -39.13dB. The gain for the ungrounded CPW fed antenna is 2.95 dB and is enhanced to 3.2dB with  grounded CPW structure. It is observed that there is an improvement in the bandwidth upto 6.03 GhZ for grounded CPW when  DGS is applied. The antenna designing and simulation is done using ANSOFT HFSS software.
