Radiation pattern of microstrip slot antenna

By Publisher

gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency.

A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern. Often the radio waves are provided by a waveguide, and the antenna consists of slots in the waveguide. Slot antennas are often used at UHF and ...

Progress In Electromagnetics Research, Vol. 144, 319{328, 2014 Frequency Reconflgurable Microstrip Patch-Slot Antenna with Directional Radiation Pattern Design And Analysis Of Compact U Slot Microstrip Patch Antenna For ...

In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source. This antenna shows a strong electric field at the top of the antenna where the slot is present.

As stated earlier, an antenna cannot radiate more total energy than is delivered to its input terminals. Antenna radiation patterns are typically presented in the form of a polar plot for a 360 degree angular pattern in one of two sweep planes. As shown in figure: 7 the value of Directivity is 5. 32dB. Design and Development of an Annular Slot Antenna (ASA ... the radiation pattern of an Annular Slot Antenna (ASA) keeping constant the frequency of operation. The planar antenna is fabricated on the top side of a Duroid substrate and the microstrip feeding line with the matching network is fabricated on the back side of the board. The design frequency is 5.8 GHz.

Directivity. • Quality Factor, Bandwidth, and Efficiency. • Antennas for Mobile Communications ... A microstrip patch antenna is a metallic strip or patch mounted.

Design of Substrate Integrated Waveguide Multi-band Slots ... Index Terms—Array, slot antenna, substrate integrated waveguide, transition. I. INTRODUCTION. Antenna is one of the important elements of the communications systems. Thus, antenna design has become one of the most active fields in the communication studies. However, there is a need for more focused radiation patterns
