A common technique to realize wideband microstrip antenna is by introducing slots at an appropriate position inside the patch. In this communication a stacked configurated microstrip patch antenna with slots similar to ISI shape introduced on a square radiating patch with a microstrip line feed is presented. The slots introduced in the radiating patch of the proposed antenna increase the fringi...

Microstrip patch antennas are well known for their advantages in terms of small weight, low profile and ease of manufacture. However, the main limiting factor in implementing these antennas in many applications is their low impedance bandwidth (typically 2-3%). One popularly used technique of enhancing the bandwidth is to use multi-layered microstrip[1,2]. The most widely accepted structure in ...

This paper present a circular patch microstrip array antenna operate in KU-band (10.9GHz – 17.25GHz). The proposed circular patch array antenna will be in light weight, flexible, slim and compact unit compare with current antenna used in KU-band. The paper also presents the detail steps of designing the circular patch microstrip array antenna. An Advance Design System (ADS) software is used to ...

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...

The dual band microstrip antenna is realized by placing the open circuit stub or by cutting the slot inside the patch. The compact microstrip antenna is realized by placing the shorting post or plate along the zero field line at the fundamental mode of the patch. In this paper, a compact variation of equilateral triangular microstrip antenna, a shorted 600 sectoral microstrip antenna is discuss...

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 ...

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

Asymmetric-circular shaped slotted microstrip patch antennas with slits are proposed for circularly polarized(CP) radiation and radio frequency identification reader applications. A single-feed configuration based asymmetric-circular shaped slotted square microstrip patches are adopted to realize the compact circularly polarized microstrip antenna. The CP radiation can be achieved by slightly a...

In this paper, the cavity model of a microstrip patch antenna in conjunction with the reciprocity theorem is used to develop a fast analytical solution for the radiation field of a microstrip patch antenna loaded with a novel artificial magnetic superstrate and to investigate the effect of the engineered superstrate layer on the directivity and radiation pattern of the printed patch antenna.
