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 A 28-GHz U-slot Microstrip Patch Antenna for 5G Applications The slot thickness of proposed antenna is 0.25 mm. As the operating frequency is high,it needs to be designed with a simple structure; therefore, a microstrip coaxial feeding line is used. For this, radius of the inner coax is 0.009 mm, radius of the outer coax is 0.03 mm and coax feed length is 1.79 mm. Design of a Rectangular Microstrip Patch Antenna Using today, and our emphasis in this work is on optimization of a 2.4 GHz rectangular Microstrip patch antenna. The return loss and the various gain plots have been studied along with the radiation patterns. Keywords: Gain, Inset feed, Patch antenna, Radiation pattern, Return Loss. I. INTRODUCTION Slot antenna - Wikipedia Slot antenna. The slot antenna was invented in 1938 by Alan Blumlein, while working for EMI. He invented it in order to produce a practical type of antenna for VHF television broadcasting that would have horizontal polarization, an omnidirectional horizontal radiation pattern and a …
The half-wave rectangular microstrip antenna has a virtual shorting plane along its center. This may be replaced with a physical shorting plane to create a quarter-wavelength microstrip antenna. This is sometimes called a half-patch. The antenna only has a single radiation edge (equivalent slot) which lowers the directivity/gain of the antenna.

EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA
The antenna pattern (or radiation pattern) is the geometric pattern of the relative strengths of the field emitted by the antenna.This power variation as a function of the arrival angle is observed in the antenna's far field. As an example, consider the 3-dimensional radiation pattern in Figure 1, plotted... Design a Microstrip Patch Antenna for Ultra Wide Band Microstrip antenna (also known as a patch antenna) is one of the latest technologies in antennas and electromagnetic applications. It's used widely in theRadiation pattern or antenna pattern can be defined as graphical or mathematical function that represents the radiation properties of the antenna. Effects of slots on microstrip patch antenna Microstrip slot antennas invented in 1938 by Alan Blumlein.Microstrip slot antenna is simple in structure. It consist of microstrip feed that couples electromagnetic waves through theThe radiation pattern by slot show the diffraction effects from the edges of finite size ground plane only affects the...

proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of It is based on coupling of an aperture between the patch antenna and Microstrip slot line.
E. Radiation Pattern 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. This
The following image shows a micro-strip or patch antenna. The length of the metal patch is λ/2. When the antenna is excited, the waves generated within the di-electric undergo reflections and the energyis radiated from the edges of the metal patch,which is very low. Radiation Pattern.
