This paper proposes a monopole antenna with photonic crystal structure as substrate for ultrawide band application with dual band notched characteristics.Improvements in all the main parameters of the antenna were obtained when using a PC.The measured results reveal that the presented dual band-notch monopole antenna offers a very wide bandwidth with two notched bands, covering 3.5/5.5-GHz WiMA...

A compact ultra wideband (UWB) monopole antenna with dual band-notched characteristics is presented. The antenna consists a square radiating patch with L shaped slots on the radiation patchand a U shaped slot as the feedline. By cutting two C-shaped slots in the ground plane, additional resonance is excited and hence much wider impedance bandwidth can produced, especially at the higher band, wh...

This paper represents microstrip antenna for dual band applications such as Global Positioning System (GPS) and Bluetooth applications. The designed antenna must perform dual frequency operation i.e. 1.57 GHz and 2.45 GHz. So antenna resonates at frequency 1.57 GHz for GPS and 2.45 GHz for Bluetooth applications. Using CAD-FEKO electromagnetic simulation software, antenna has been optimized for...

This paper introduces the design of a new dual-band internal printed monopole antenna structure as a candidate for WLAN (wireless local area network) USB (universal serial bus) dongle applications. The proposed antenna structure is based on the second iteration of Peanotype space-filling geometry. The antenna has been printed on a substrate with relative permittivity of 2.33 and thickness of 0....

Abstract—In this paper, we use the concept of stub loadings of planar microstrip antennas to convert a single band antenna into a dual-band antenna used for WLAN. We load a planar triangular monopole (PTM) antenna by combline stubs attached to the edges of patch in order to obtain a second resonance frequency. The simple PTM antenna is first designed to produce the lower resonance frequency and...

The dual band microstrip antenna is realized by placing the open circuit stub or by cutting the slot inside the patch. The compact microstrip antenna is realized by placing the shorting post or plate along the zero field line at the fundamental mode of the patch. In this paper, a compact variation of equilateral triangular microstrip antenna, a shorted 600 sectoral microstrip antenna is discuss...

Microstrip antennas are low in profile and light in weight and they are now developed for many applications. The main difficulty of the microstrip antenna is its narrow bandwidth. Several modern applications like satellite communications, remote sensing and multi-function radar systems will find it useful if there is a dual band antenna operating from a single aperture. Some applications requir...

A compact dual-band dual-polarized antenna is proposed in this paper. The two pair dipoles with strong end coupling are used for the lower frequency band, and cross-placed patch dipoles are used for the upper frequency band. The ends of the dipoles for lower frequency band are bent to increase the coupling between adjacent dipoles, which can benefit the compactness and bandwidth of the antenna....

A dual-band Planar inverted-F antenna (PIFA) for wireless applications has been presented in this paper. The proposed antenna is compact in size and design on FR4 substrate. The antenna consists of a slotted radiator supported by shorting walls and a small ground plane. Square shaped slot in radiating patch have been used to introduce dual band operation into the proposed antenna. The structure...

A coupled-line-based planar antenna for single-band and dual-band operation is presented. The well-known uniplanar coupled inverted-L antenna (UCILA) has a simple and specific mechanism to achieve the dual-band ratio that was not described in the past. The UCILA which shunted a short stub in the slotline portion can provide switchable modes among single-low band (3.4% for WLAN 2.44GHz), single-...
