چکیده
A new planar antenna with double access and three separated bands is presented in this article. The first access operates over two bands, a narrow band for GPS standard (1.575 GHz), and a wideband covering PCS (1.85-1.99 GHZ) and UMTS (1.92-2.17 GHz) standards and also six sub bands of the new norm 3GPP (LTE). The second access operates over a wideband covering WLAN applications (2.4-2.484 GHz) and a sub band of LTE (called also IMT-2000). In total, this antenna covers eleven standards. A new analysis method for bandwidth improvement techniques (parasitic patch) using the equivalent cavity modal analysis is also presented. Simulation and measurement results are proposed.

متن کاملAn Improved CPW-Fed Printed UWB Antenna With Controllable Band-notched Functions
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...

Band-notch characteristic has been of great interest recently to overcome the electromagnetic interference of Ultra-wideband systems (UWB) with other existing ones. In this paper, we present a novel microstrip-fed antenna with band rejection property appropriate for UWB applications. Band-notch characteristic has been achieved by adding a rectangular resonant element to the ground section. A pr...

متن کاملModified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band
The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
