This paper proposes a compact printed monopole antenna with dual band-notched characteristics for ultrawideband application. The proposed antenna consist two inverted T-shaped slots in radiating patch, which provides dual band-notched characteristics and partial ground plane with a slit, which provides large usable fractional bandwidth 129% (2.8-13.1 GHz).The upper inverted T-shaped slot provid...

Several wideband antennas are presented for either wireless application. This paper presents the performance of a simple monopole antenna loaded with an annular dielectric resonator as a wideband transmitting/receiving antenna. By adjusting the length of the monopole and load arm, a 10-dB bandwidth of 94% is achieved while maintaining monopole-like radiation pattern, which covers UWB applicatio...

In this paper a microstrip transmission line fed compact monopole antenna for the wide-band (2. 5 GHz 11 GHz) communication system is designed and its performance is verified. In particular, we have simulated four types of wideband monopole antennas: rectangular, modified rectangular, circular and modified circular disk monopole antennas. Simple rectangular microstrip lines are used for feeding...

In this article, a printed ultra-wideband (UWB) monopole antenna with dual band-notched characteristics of size 26mm×35mm is presented. The prototype consists of pincers-shaped radiation element and corner rounded ground plane. By inserting a pair of flexuous slots on the radiation element and a C-shaped slot on the ground plane, the 3.5/5.5 GHz dual band-notched characteristics are achieved, r...

This article describes the construction of a dual-band planar monopole antenna. A microstrip patch antenna with feedline impedance 50 ohm and composed G-shaped inverted L-shaped strips is used to make suggested ultra wideband for frequencies ranging from 3.1 10.6 GHz. In order design antennas, we need know dimensions 40x40x1.6 mm3 thickness ground plane (0.035 mm) (5.2 GHz). There method alteri...

A compact size low profile microstrip-fed crossed monopole antenna for ultra wideband communication is presented. The impedance bandwidth of a microstrip crossed monopole antenna has increased with a suitable dimension of ground plane and rectangular patch. The aim of this paper is to improved bandwidth and return loss of a Crossed Monopole Microstrip patch antenna and study the effect of anten...

A high performance monopole antenna fabricated using a folded wire line and metal patch as radiator is presented. A prototype of the proposed monopole antenna with a compact area size is implemented, and the multi-band WLAN antenna shows a wide operating bandwidth of about 530MHz and 3400MHz for low band and high band, bandwidth, making it easy to cover the IEEE 802.11a, IEEE 802.11b, IEEE 802....
