381 Abstract— A monopole triangular shaped, broadband, compact microstrip patch antenna with shorting pin is presented in this paper. By defecting the ground plane bandwidth of 38.7% with respect to center frequency of a Microstrip patch antenna has been achieved which can be used for WLAN application. 82.4% size reduction has also been achieved by using shorting pin of a microstrip patch anten...

In this paper, an optimal approach to design wideband tapped-delay line (TDL) array antenna is proposed. This approach lets us control the array angular and frequency response over a wide frequency band. To this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. The optimal weights of the TDL proce...

This article develops a broadband absorber by fully using the radiation features of monopole antennas for ultrawide-angle absorption application. A unit cell (UC) based on is proposed, and its working polarization analyzed with antenna reciprocity method image theory. wide-angle impedance matching layer also introduced to further enhance at large angles. The optimized monopole-based UC reveals ...

In this manuscript, a novel design of ultra-wideband (UWB) monopole antenna with dual frequency band-stop performance is proposed. The proposed antenna consists of an ordinary square radiating patch with a pair of rotated T-shaped slits, and a modified ground plane with an inverted Ω-shaped and a pair of rectangular-ring slots. In the presented structure, by cutting a pair of rectangularring sl...

In this paper, we present a compact and low-profile monopole antenna with a simple structure for the 2.6-2.73 GHz frequency band, the Worldwide Interoperability for Microwave Access (WiMAX) and the Wireless Local Area Network (WLAN) applications. The first configuration of our antenna mainly consists by three radiating elements: inverted L-shaped Stub1, L-shaped Stub2 and a rectangle Stub3. By ...

Folded monopole antennas have been used for many years in medium frequency amplitude modulation broadcast applications. These antennas offer a grounded radiating structure with a height approximating a quarter wavelength. Folded monopoles have been studied exhaustively during a recent effort in an attempt to characterize the input impedance and directivity characteristics as a function of monop...

The monopole resonator antenna which is used to radiate in the omni directional pattern is used for multi broadcasting. Ultra wide band antenna technology is used for transmitting ...

Anultra-wideband (UWB) bowl-shaped monopole antenna with a sturdy, simple, and lightweight structure is proposed, then used to compose the 3 × multiple input output (MIMO) antenna. The wide bandwidth determined by outline of monopole, which has quarter wavelength high-order modes. inner part removed for light weight. simulated measured results show that an ultra-wide band 2.3–8.1 GHz (5.8 GHz, ...

This paper presents the design equations for lower band-edge frequency for all the regular shapes of printed monopole antennas with various feed positions. The length of the feed transmission line is a critical design parameter of these monopole antennas. Design curves for the length of the feed transmission line for various lower band-edge frequencies for all these regular shaped monopoles hav...

Abstract— Miniaturized structure and multiple band performance of a patch antenna are primary requirements for modern wireless communication systems. In this paper, a novel design of monopole dual band microstrip patch antenna with circular ring has been proposed for S and C band applications. For dual bands (4.0 GHz and 4.68 GHz), proposed patch antenna shows quite satisfactory radiation perfo...
