CPW‐FED compact bent monopole antenna for UWB applications

Abstract

A compact CPW‐fed planar antenna suitable for ultra‐wideband (UWB) applications is presented.The proposed design is a modification of the simple monopole antenna where the monopole is folded and the asymmetric ground plane dimensions are optimized for UWB performance. The simple geometry and its compactness make the antenna good candidate for portable applications involving integration with microwave monolithic integrated circuit (MMIC) devices. The antenna fabricated on FR4 substrate shows almost identical radiation characteristics in the entire band with an average gain of 2.5 dBi. © 2012 Wiley Periodicals, Inc.

Design and performance analysis of broadband rectenna for an efficient RF energy harvesting application

“…The CPW fed slot antenna is used as a receiving element which receives the RF energy from the environment. Microstrip line, coplanar strip line (CPS) and coplanar waveguide are the transmission lines used for the rectenna . Compared with the CPS and the CPW, the microstrip line needs a ground via for connecting the active components present in the rectifier.…”

Four-element planar array antenna for UWB application

“…The feeding network with a large size and compact structure [3][4] is not convenient for highly integration. Several research literatures about the planar antenna with various feeding structure [4][5][6] Fig.6, there is a similar trend between the simulated and measured result, but the measured result is inferior to the simulated result. It is interesting to note that the proposed antenna has a lower low cut-off frequency than the simulation.…”

Very compact palmate leaf‐shaped CPW‐FED monopole antenna for UWB applications

“…The ground plane of the proposed antenna is designed to have nonrectangular shape by cutting the upper left and right corners of the rectangular shape. The truncated ground plane effectively enhances the antenna impedance bandwidth .…”

“…The CPW feed line is preferred due to its small size, low profile, low radiation loss, and easy integration with microwave monolithic integrated circuit (MMIC). Hence, many planar CPW‐fed antenna configurations have been designed and developed .…”
