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 Slots are basically used for Bandwidth enhancement and for compactness of antenna. The antenna is designed at some particular resonating frequency which gives some bandwidth then addition of slot overlaps the fundamental mode of antenna and create...

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- On the Use of Slots in the Design of Patch Antennas antenna design are based on one or more of the following principles: A. Thick substrates of low permittivity are used. B. A scheme is devised to reduce the mismatch problem associated with thick substrates. C. By means of parasitic elements or slots, either new resonances are introduced close to the main resonance or existing Frequency tuning and miniaturization of square microstrip ...

Broadband Slot Cut Rectangular Microstrip Antenna - CyberLeninka
An individual microstrip antenna consists of a patch of metal foil of various shapes (a patch antenna) on the surface of a PCB ... These slots act as an array and have the highest directivity when the antenna has an air dielectric and decreases as the antenna is ... Broadband Slot Cut Rectangular Microstrip Antenna - ScienceDirect 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. The slot reduces ...
This paper presents effect of slots on microstrip patch antenna and its parameters. The effect is shown on bandwidth, gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency.

Microstrip Patch Antennas - University of Texas at El Paso
antenna and improvement in bandwidth can be achieved by etching the slot in ground and patch of Microstrip antenna of proper length and width [5-7]. This paper concentrates on the effect on antenna resonant frequency and other antenna parameters due to slots in patch and ground plane to design the compact antenna with improved bandwidth and
