A novel technique fitr the bat dividth enhancement of conventional rectangular microstrip antenna is proposed in this paper. When a high permittivity dielectric resonator of suitable resonant frequency was loaded over the patch. the % bandwidth of the antenna was increased by more than five tunes without much affecting its gain and radiation performance. A much more improved bandwidth was obtai...

In this paper, a rectangular slotted microstrip patch antenna with partially loaded metamaterial multiple-split ring resonator (MSRR) ground plane is presented. In unloaded condition, the rectangular slotted patch antenna resonates at 9.38 GHz. When the same antenna is loaded with MSRR in the ground plane, it resonates at lower resonant frequencies 4.60 GHz and 7.70 GHz respectively. The mutual...

A low-profile microstrip planar monopole antenna with triple-band operation for WiMAX and WLAN applications is proposed. The antenna has a simple structure which consists of a rectangular radiation patch with an L-shaped slot and an inverted L-shaped stub extending from the ground plane. By etching an L-shaped slot on the rectangular radiation patch, the antenna can excite two resonant modes. T...

Abstract: In this paper, a new design for microstrip antenna element with U-shaped rectangular patch for sectored coverage of base station antennas of 900 MHz system is proposed for improving antenna performance in terms of gain and bandwidth. A superstrate or dielectric cover is used to protect the patch against environmental hazard. We have present also another solution using air dielectric a...

This paper presents a Neural Network model for the design of Micro-strip Antenna for Ultra wideband (UWB) applications which can be operated in a desired frequency range between 2 GHz to 20 GHz. Artificial neural network based on back -propagation (BP) and radial basis network (RBN) algorithms have been used in designing rectangular patch antenna highlighting the difference between them and the...

A single feed compact square microstrip antenna is proposed in this paper. Two L slits are introduced on the right edge of the patch to study the effect of the slit on radiation behavior with respect to a conventional microstrip patch. An extensive analysis of the return loss, radiation pattern and efficiency of the proposed antenna is shown in this paper. For the optimize value of the slit par...

In this paper, microstrip patch antennas with six different shapes i. e. rectangular, circular, square, elliptical, pentagonal and hexagonal are implemented using Ansoft HFSS version 13. 0. 0 software. Antennas are designed on Rogers RT/duroid 5880 material with dielectric constant 2. 2 and thickness 3. 2 mm. The different performance parameters such as return loss, gain and bandwidth of these ...
