Abstract—A compact wide-slot antenna fed by microstrip-line for wideband operation is proposed and studied. The proposed antenna consists of a microstrip-fed line and a wide rectangular slot with a reverse L-shaped slot. The proposed antenna resonates the 10-dB bandwidth from 2.17 GHz to 6.25GHz, and these frequency bands cover the standard IEEE 802.11b/g (2.4–2.485 GHz) and IEEE 802.11a (5.15–...

In this paper hexagonal patch shape with hexagonal slot, ultra wideband antenna is proposed. The total dimensions of antenna are 55×43.5mm. Sides of hexagonal patch are taken 13mm each and hexagonal slot sides are taken as 3mm each. The antenna resonates at two frequencies in ultra wideband range (UWB). There is enhancement in BW in upper range ultra wideband frequency from 6.2 GHz to 8.2GHz du...

Metamaterial structures have unique properties in controlling the propagation of electromagnetic waves. In this work, we analyze the effect of artificial magnetic conductor (AMC) surface strips on the bottom face of an oversized parallel plate waveguide to enhance the wave guidance within it. The results using these configurations in a linear slot array antenna fed by a rectangular parallel pla...

In this paper, an efficient implementation of the spectral domain moment technique is presented for computing the self and mutual coupling between slot antennas on a dielectric half-space. It is demonstrated that by the proper selection of the weighting functions in the method of moments, the analytic evaluation or simplification of the transverse moment integrals is enabled. This results into ...

A low-gain crossed-slot microstrip patch antenna integrated with the solar-array panel has been successfully developed for the Mars rover application at the frequency of 400 MHz. It achieved a very low mass of 0.5 kg and occupied very small real estate (6.5 percent) of the solar panel. The electrical and mechanical characteristics of several other omni-directional low-gain antennas also are dis...

Different fractal based structures have been widely used in numerous antenna designs for various applications. In this paper, a printed slot antenna has been introduced as a candidate for use in the dual band wireless communication applications. The antenna slot structure is in the form of a Sierpinski gasket of the first iteration. The antenna has been fed with 50Ohm microstrip transmission li...

This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...
