چکیده
In this paper, the design and analysis of a compact size coplanar waveguide (CPW)-fed antenna for ultrawideband (UWB) applications is presented. The antenna has a compact size of 20×20× 1.5 mm and provides a good impedance matching over the entire bandwidth of 3.2–14.3 GHz. The characteristics parameters, i.e. return loss, VSWR and radiation pattern, are analyzed using HFSS 11.0 software. Keywords—planar antenna, ultra wideband, wireless communication.

Compact CPW-fed Circular Patch Antenna for UWB Applications
In this paper, a novel CPW-fed antenna is presented for UWB applications. The antenna mainly comprises of a simple circular patch and a modified ground plane. The inclusion of two novel symmetrical rectangular slots with inner area of 3×2.8 mm2 to the top corners of the antenna creates a new path for the current and consequently leads to the bandwidth enhancement. A rectangular stub is also ado...

A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...
متن کاملDesign of A Compact CPW-FED UWB Antenna with WiMAX and WLAN Band-Notched Characteristic Evaluated in AHP Framework
In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators. The proposed antenna can operate from 2.82 to 11 GHz (118%), defined by VSWR< 2, except two notched bands around 3.5 GHz (WiMAX) and 5.5 GHz (WLAN)...

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...

In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition) a...
