چکیده
In this paper, a circular slot antenna fed by an offset microstrip-fed line is proposed. The antenna exhibits dual-band characteristics. The two operating frequency bands are: 1.83–2.73 GHz and 5.36–7.63GHz, which are of impedance bandwidth 39.5% and 34.9% respectively. The bands are suitable for PCS, UMTS, IMT2000, ISM, Bluetooth, RFID and WLAN applications. A parametric study has been carried out by varying the location of the feedline to investigate its effect on the resonant frequency. Impedance, radiation and gain characteristics of the proposed antenna are also presented and discussed.

Multi Attribute Analysis of a Novel Compact UWB Antenna with Via-fed Elements for Dual Band Notch Function (RESEARCH NOTE)
A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...

An internal triple-band antenna fed by a microstrip line is proposed for operating PCS, IMT-2000, and Bluetooth bands. By using the two branchs of meander line, the desired resonant frequencies can be achieved. A broadband characteristic for each band is optimized by tunning the parts of radiating patch and size of each strip line segments. The proposed antenna and substrate are small enough to...

This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...
