A single layer monpole slotted patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting three equal slots which are same hexagonal structure at the upper right, upper left, lower left corner and a circle at the center from the conventional microstrip patch antenna. It is shown that the simulated results are in acceptable agreement. More imp...

This paper presents air gap aperture coupled microstrip antenna for dual-band operation over the frequency range of (2.9 to 6.0 GHz). This antenna differs from any other microstrip antenna with their feeding structure of the radiating patch element. Input signal couples to the radiating patch trough the aperture that exists on the ground plane of microstrip feed line. The dual-band achieved by ...

Microstrip antenna is gathering a lot of interest in communication systems. Genetic algorithm is a popular optimization technique and has been introduced for design optimization of proximity coupled antenna. Patch length, patch width are taken as optimization parameters. Return loss and radiation pattern for the optimized antenna are verified using IE3D software. Accuracy of the results encoura...

some analysis has been presented on a circularly polarized microstrip antenna with T slot configurations in detail. Here we will design a T-slot coupled circularly polarized microstrip antenna in the frequency 1.575 GHz. The upper patch i.e. the radiating patch would be circular. There is no closed form expression so that by using that expression the dimensions of the proposed antenna could be ...

This paper demonstrates the Dual band Broadband microstrip patch antenna with air gap for wireless applications with improved bandwidth and gain. The antenna have dual bandwidths of 860MHz (4.40GHz – 5.26GHz) or 17.61% and 1670MHz (5.33GHz – 7GHz) or 27.08% covers four bands of WLAN and one band of Wi-Max and one band of IMT. The designed antenna has four resonant frequencies 4.52GHz, 5.67GHz, ...

Abstract:In telecommunications, there are several types of microstrip antennas, the most common of which is microstrip patch antenna. Patch antennas are also relatively inexpensive to manufacture and design because of simple 2D physical geometry. In this paper Two L slits are introduced at the both edge of the patch to reduce the resonant frequency. The proposed antenna is developed to operate ...

In recent years, microstrip antennas become very popular because of their interesting advantages of low cost, low profile, light weight, easy fabrication and ease of analysis. Electromagnetic Band Gap (EBG) substrate is used as a part of antenna structure to improve the performance of the patch antenna. Usually, the performance of a patch antenna depends on the parameters such as Return Loss (R...

A new Sierpienski & Crown Square Fractal Shapes Slotted Microstrip Patch Antenna is proposed. A patch antenna is a narrowband, wide-beam antenna. These antennas are low profile, conformal to planar and non-planar surface, simple and inexpensive to manufacture using modern printed circuit technology, mechanically robust when mounted on rigid surface, compatible with MMIC designs and when the par...

We present microstrip patch antenna loaded with multiple split ring resonator substrate and superstrate. We analyze how the loading of split ring resonator superstrate and substrate can improve the bandwidth compared to the simple microstrip patch antenna and microstrip patch antenna loaded with split ring resonator superstrate. Another important observation is made for multiple split ring reso...
