Effect of slots on microstrip antenna

microstrip antenna,these slots are square rectangula r,cross ,U,H etc.The effect of changing The slot length and width are studied on parameters like gain,return loss, radiation efficiency,antenna efficiency etc.A coaxial probe feed is used at different points by changing the feed locations and their effect are seen on

Effects of Square- and Rectangular-Shaped Slots Kept Over ...

The most commonly employed microstrip antenna is a rectangular patch which looks like a truncated microstrip transmission line. It is approximately of one-half wavelength long. When air is used as the dielectric substrate, the length of the rectangular microstrip antenna is approximately one-half of a free-space wavelength. Broadband Slot Cut Rectangular Microstrip Antenna Variation of E-shaped Microstrip antenna, a broadband rectangular Microstrip antenna cut with three unequal length rectangular slots is proposed. A detail analysis to study the effects of rectangular slots that realizes broader bandwidth is presented. What is the difference between slot antenna and patch antenna ... Before one explains what the question asks, for let us compare the solitary dipole antenna with the slot antenna, each of the same length. One may look at the dipole as a length of conductive material equal to half a wavelength, placed and surrounded by a large sheet of insulating space, if one considers one plane in which the dipole is placed. How does a slot effect an antenna’s bandwidth? - Quora

Microstrip Antennas – Part 2 - McMaster University

This paper presents the numerical simulation of double U-slots microstrip patch antenna for WiMAX application. The proposed antenna is feed by the Transmission line. The total area occupies by the antenna 40mmx47mm. In this design two slots and one bridge elements have been ap-

In order to design a microstrip patch antenna at first the designer is to select the substrate material and it’s thickness. So, if the designer has a clear conception about the effect of changing substrate material and it’s thickness on the performance of the antenna, it will be easier to design an antenna.

Effect of Open Stub Slots for Enhancing the Bandwidth of Rectangular Microstrip Antenna 225 bandwidth of 24.62% when compared to BW6. Hence the use of closed slot at the centre of TSRMA is more useful in enhancing the secondary band i.e. BW8 of antenna. Since the separation between BW7 and BW8 is quite large Microstrip Antennas – Part 2 - McMaster University
