چکیده
In this paper a low profile, small size polygon slot CPW fed antenna for broadband application is presented. The proposed antenna comprises of simple polygon radiator and rectangular ground plane. It resonates at 4.9 and 8.4 GHz frequency where return loss is well below to -10 dB. The proposed antenna is designed with FR4 epoxy substrate having dielectric constant of 4.4 and loss tangent of 0.02 and overall size 19x 21x 0.8 mm. The antenna is designed using simulation tool Mentor graphics 15.10 version which is based on method of moments (MoM). Simulation results show that the axial ratio (AR) bandwidth is as large as 115.4% (4.1 GHZ15.3 GHz) with VSWR≤ 2, which makes the antenna be used for broad band and ultra wideband (UWB) applications also.

CPW-Fed Circularly Polarized Slot ANTENNA with Elliptical-Shaped Patch for UWB Applications
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...

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...

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)...
