Aug 18, 2011 · Abstract: A compact open-slot antenna for bandwidth enhancement is presented. Multiple resonances are generated by using an asymmetrical rectangular patch with the U-shaped open-slot structure. Two bevels are cut on the patch to improve the impedance matching. Printed Wide-Slot Antenna Design with Bandwidth and Gain Feb 13, 2014 · This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement. An I-shaped microstrip line is used to excite the square slot. Enhancing the Bandwidth of a Microstrip Patch Antenna dielectric constant of 9.4 and loss tangent of 4.0e-4. The proposed antennas may find applications in Wireless Local Area Network (WLAN). Keywords: - bandwidth, dielectric constant, microstrip antenna, slot patch, substrate I. INTRODUCTION Communication can be broadly defined as the transfer of information from one point to another [1]. How can I increase the bandwidth of a microstrip patch

In this paper, we design and simulation of an improved bandwidth V-slotted Patch Antenna for WiMAX which is operated for WLAN applications is used as a based model. It is proposed that by the use of the corner truncated patch scheme we can widen the operational bandwidth of the antenna and can achieve
Antenna designs were achieved for wideband operation by the use of a coplanar patch-slot antenna, fed by a coplanar waveguide. This design is easily tuned to operate at 2.45 and 5.75 GHz, with wide bandwidth for wireless systems. The oper- ating frequency is controlled by modifying the patch dimensions. How do I change the antenna structure to improve bandwidth? With decrease in dielectric constant both the resonant frequency as well as the bandwidth increases. so try using a subtsrate with low dielectric constant. OR. feed the antenna using aperture slot coupling. aperture slot coupling has the advantage of providing increased bandwidth compared to any other feeding mechanisms. OR Rectangular Microstrip Antenna on Ridge Ground Plane to ...
