An improvement of the fractal antenna is made to enhance its gain and bandwidth. In this paper, a relative study of the fractal antenna which is excited by the CPW is done. The antenna that we proposed was designed and simulated using HFSS. Using the fractal concept and CPW-feed technique the compact size and the ultra wideband impedance matching is obtained. The final dimensions of the designed antenna measure 36.4mm x 40mm x 1.53mm.A low-cost FR-4 substrate is used in this design. The UWB characteristic of the antenna ranges from 3.137GHz-11.4332GHz with a notch band from 3.7716 GHz to 4.07 GHz. The designed antenna is mainly used for the UWB pulse based trans-receiving applications.

This article presents the design and analysis of frequency tunable circular monopole antenna with notch band characteristics. The proposed antenna consisting of slots on the radiating element to attain notch bands in the ultra wideband (UWB). The dimensions of the slots are properly adjusted and optimized to obtain the desired band rejection response. Two PIN diodes are connected between stubs and the feed line to obtain the tenability in the notch bands. The switching operation between the diodes, controlling the length of the radiating structure and intern affecting the reconfigurable behaviour in the antenna. The overall dimension of the antenna is very compact and occupying around 44X40X1.6 mm on FR4 substrate with dielectric constant 4.4 and loss tangent 0.02. The proposed antenna initially notching WiMAX and WLAN operating bands of 3.1-3.7 GHz and 5.1-5.8 GHz and frequency tenability is analyzed with diodes switching condition to notch other communication application bands. The simulation results of reflection coefficient, radiation patterns and gain obtained from CST microwave studio and real-time measurements from prototyped antenna demonstrates the excellent working characteristics of the notch band antenna with tunable behaviour.

Antenna miniaturization, which is a requirement of modern wireless communication systems, is usually concomitant with the reduction of impedance bandwidth. On the other hand, small antennas should also possess stable radiation patterns across a broad frequency band, such as in UWB systems. In this paper, we propose a UWB antenna structure with a novel feeding system composed of an open cavity resonator. It has a wide relative bandwidth (of about 120%) particularly at the lower frequency limits. The variation of radiation pattern across its operating bandwidth is also negligible. The proposed antenna with the novel feed system is smaller and has a wider frequency bandwidth than other available UWB antennas in the literature. Furthermore, another antenna is proposed, which has a feeding system composed of a surface integrated resonator cavity, fabricated on a two-layer microstrip structure. It has achieved better miniaturization and bandwidth, albeit somewhat lower gain. Three prototype models of the proposed antennas are fabricated and measured, of which the frequency response is in excellent agreement with computer simulation results.
