This paper introduces a new geometry of a rectangular microstrip patch antenna that improves the performance of a conventional microstrip patch antenna .This antenna is designed to operate at 5.38 GHz with enhanced bandwidth of 11.15%. For the desired result, a triangular notch is inserted into the patch antenna. The proposed geometry provides improvement in other radiation parameters like gain...

Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...

This paper presents the design of rectangular, fractal Microstrip patch antenna and their backscattering reduction. These antennas have been designed on εr = 4.3, h = 1.53 mm substrate with rectangular patch dimension 36.08 x 29.6 mm and its 2 iterative fractal patch. The experimental resonant frequency of 2 iterative fractal patch is observed 2.11 GHz in comparison to rectangular patch 2.42 GH...

The microstrip patch is one of the most preferred antenna structures for ofordable and compact design for wireless system and RF applications. This paper compares the rectangular patch antenna and equilateral triangular microstrip antenna in terms of their return losses and radiation pattern. For the comparative study the Ansoft HFSS V11 is used. Keywords— rectangular micro strip antenna, retur...

The paper presents a broadband microstrip patch antenna for wireless communication. In its most basic form, a microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side. The patch is generally made of conducting material such as copper or gold and can take any possible shape. A rectangular patch is used as the main rad...

Despite the many advantages of microstrip patch antennas, they do have some considerable drawbacks. One of the main limitations with patch antennas is their inherently narrowband performance due to its resonant nature. With bandwidth as low as a few percent; broadband applications using conventional patch designs are limited. So for the antenna miniaturization and bandwidth improvement H-shaped...

In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...

In this present work, Rectangular Microstrip Patch antenna loaded with symmetrically cut H and hexagonal shaped metamaterial (MTM) is proposed for better improvement in the impedance bandwidth and reduction in the return loss at operating frequency 1.794 GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane. At 1.794 GHz, the bandwidth is increased up to 27 MHz in compa...

This paper proposes the rectangular microstrip patch antenna suitable to operate in different frequency bands. The rectangular microstrip patch antenna is designed and simulated using IE3D simulation software. The result obtained shows that the designed antenna is suitable for operation in four different frequency bands with bandwidth of 6.90%, 2.33%, 12.02% and 2.74% .The resonating behavior i...
