This paper presents a compact antenna with co-planar waveguide (CPW) feed line for ultra-wideband (UWB) applications. The proposed antenna consists of a beveled radiating patch with wide rectangular slit at its upper side and a partial ground plane with insertion of symmetrically two-step beveled tapers at its center and sides, which provides a wide operating bandwidth. to the standard one-wavelength CPW-fed slot antenna (Fig. 1). The generalized CPW open-end structure can be considered as a slotline resonator shorted at two ends and fed symmetrically on its length by the two slots of the CPW feed line. A compact CPW-fed ultra-wideband monopole antennas with band notch characteristics using Split Ring Slots (SRSs) are proposed in this manuscript. Initially, the antenna is designed by using a rectangular shaped patch, and it has been modified to obtain enhanced impedance bandwidth (VSWR ≤ 2) throughout the entire UWB frequency range.

Two metal stubs are introduced in the middle of the bow-tie slot in order to achieve a wider impedance bandwidth over the conventional CPW-fed bow-tie slot antenna. The antenna is fabricated and tested in the antenna measurement facility of UCL and experimental far-field results are presented showing low cross-polarisation levels. strip line fed circular slot can operate over the entire UWB band, i.e. from 3.1GHz to 10.6GHz. However, the antenna size is big and the slot diameter is 65.2mm. In this report we have used slot antenna having CPW feed and the shape of the slot antenna is circular. A CPW‐fed bow‐tie slot antenna is presented. Experimental results show that the widest bandwidth can be adjusted by the slot width when the extended angle is zero, while the far field is in the broadside direction and the cross polarization is kept at a low level.

CPW bow tie slot antenna is having more advantages over micro-strip antennas such as wide bandwidth, high gain, less dispersion, impedance matching. 5.We can achieve UWB with CPW fed…

The antenna pattern comprises a circular patch with the double stepped symmetric ground plane and is fed by a coplanar waveguide (CPW) technique on one-sided photo paper. The broadband characteristics are achieved using a coplanar‐waveguide (CPW)‐fed two‐arm spiral slot configuration. The spiral slot antenna and the feeding structure are fabricated on the same plane of the substrate so that the circuit process and the position alignment could be simplified. A compact CPW-fed slot antenna is proposed here. The antenna has a pentagonal patch nested within an asymmetrical slot along with a coplanar waveguide feed. The suggested antenna also has a circular polarization over a wide range. May 28, 2015 · A new coplanner waveguide‐fed broadband circularly polarized (CP) rectangular slot antenna is proposed. Circular polarization (CP) is obtained using L‐shaped feed line protruded from the signal line and rectangle‐shaped parasitic element (PE). A compact low-profile wideband circularly polarized slot antenna for global navigation satellite system (GNSS) is presented. The antenna comprises a planar slot radiator with a coplanar waveguide (CPW) feed and a modified ring-shaped reflector to achieve unidirectional radiation. single feed. Though some circularly polarized slot antenna designs have been reported, most of these reported antennas are fed by a microstripline [9–11]. The design fed by a CPW [12, 13] is relatively scant. Meanwhile, most of the reported CPW-fed slot antennas produce bidirectional radiation; as a result the antenna gain is relatively low.

Jan 01, 2020 · The proposed antenna contains two identical monopoles that are placed parallel to each other and which are fed by a 50-ohm coplanar waveguide (CPW). The MIMO antenna is fabricated on a low-cost flame resistant 4 (FR4) substrate with an overall size of 36 × 36 × 1.6 mm3.
