A wideband planar monopole antenna with an L-shape ground plane is presented. The antenna also has a frequency-notching characteristic. By etching a half-wavelength U-shaped slot in the interior of the radiation element, the frequency-notching characteristic has been created. This paper presents the design and experimental results of the proposed antenna. Moreover, the study also investigates t...

A novel modified printed monopole antenna with variable frequency band-notch characteristic for ultra-wideband (UWB) applications is presented. The proposed antenna consists of a truncated ground plane and a radiating patch with two tapered steps. To generate a notch band at 5–6GHz with good level of band-notch a new T-shaped parasitic element placed on the back layer of the substrate along wit...

The fractal antennas that have the multiband operation due to the self-similar property in fractal geometry, which plays a key role to create a fractal circular monopole patch antenna. The other important property that is, Space-filling property which actually determines the reduction in the size of the antenna. This property adds more electrical length in less volume which reduces the size of ...

In this paper we have investigated compact printed semicircular disc monopole antenna, which is basically printed microstrip antenna with etched ground plane for UWB applications. In particular we have simulated very compact semicircular disc monopole antennas for UWB communication. Simple rectangular microstrip line is used for feeding the printed monopole antenna and its frequency bandwidth u...

In this paper, a compact UWB printed monopole antenna design is proposed. The monopole antenna has the form of an E-shaped structure printed on a substrate with relative dielectric constant of 3.38, and thickness of 1.52mm. The matching through the UWB response is satisfied using a reduced ground plane. The proposed antenna is fed by a 50 Ω unsymmetrical microstrip line. The ground plane is pri...

Abstract A simple low profile defected ground structure based monopole circular-shaped patch antenna is proposing for ultrawide-band applications. The design allows a and compact on the FR-4 substrate material. proposed initially has meager gain bandwidth. To increase bandwidth gain, defective implemented with four dumble-shaped slots. Parametric analysis considered to find radius of circular t...

In this letter, a compact planar ultra-wideband mobile antenna with L-shaped extended ground stubs is presented. The proposed handset antenna consists of two planar meandered monopole radiating elements, i.e., main antenna and auxiliary antenna respectively, located at the diagonal corners of mobile phone printed circuit broad with standard size of 136 × 68mm2. Each radiating element is compose...
