Slot antenna - Wikipedia 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. Dual Band Semi Circular Disk Patch Antenna Loaded with L-Shaped…
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...
Micro strip slot antennas (MSAs) have the advantages of being able to produce bidirectional and unidirectional radiation patterns with larger bandwidth and very low cross polarization (typically -35dB) as compared to microstrip patch antenna [2]. In, Microstrip slot antenna, the strip and slot combination offer an additional degree of freedom ... Electronic Warfare and Radar Systems Engineering Handbook RADIATION PATTERNS. Patterns are normalized to the maximum graph value, 0 dB, and a directivity is given for the antenna. This means that if the side lobe level from the radiation pattern were down -13 dB, and the directivity of the antenna was 4 dB, then the sidelobe gain would be -9 dB. Design of a Rectangular Microstrip Patch Antenna Using ... Microstrip patch antenna. The design and simulation of patch antennas is widely used in mobile cellular phones 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. Slot Antenna Uses Dual Polarization | Microwaves & Radio ... The antenna radiates in a broadside direction and features almost symmetrical radiation patterns in both the E- and H-plane directions. As Fig. 4 shows, the antenna’s cross-polarization remains under -35 Db; the front-to-back ratio is less than 18 dB; and the half-power beamwidth is about 108 deg. in the E-plane and 92 deg. in the H-plane.

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 ...
