Radiation pattern of microstrip slot antenna

Slot Microstrip Antenna for 2.4GHz RFID Reader Application

SpecificationsEdit. The radiation from a rectangular microstrip antenna may be understood as a pair of equivalent slots. These slots act as an array and have the highest directivity when the antenna has an air dielectric and decreases as the antenna is loaded by material with increasing relative dielectric constant. A Hexagonal Shape Microstrip Slot Antenna for ... - IJSER 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.

2. Radiation Pattern Of Different Slot Microstrip Antennas. The E&H plane radiation pattern of cross shaped slotted patch antenna at 2.5GHz is shown in fig.11. This radiation pattern is similar to that of a conventional half wavelength dipole antenna which has a figure eight radiation.

A. Antenna Design A resonant narrow slot antenna is equivalent to a magnetic dipole, and at its first resonant frequency it has an equivalent length of ( is the guided wavelength in the slot). If the slot antenna is fed near an edge by a microstrip line and the slot width is properly chosen, at a frequency above the first slot res- Design of Slot Antenna for Wideband Applications - ERNET

In telecommunication, a microstrip antenna (also known as a printed antenna) usually means an antenna fabriciated using microstrip techniques on a printed circuit board (PCB). It is a kind of internal antenna. Slot Microstrip Antenna for 2.4GHz RFID Reader Application Fig 5 shows the radiation pattern of the antenna with slot and shorting wall. There is a strong electric field at the top of the antenna where the slot is present This shows that the slot acts as a capacitive coupling structure so as to produce the required electric field at the required frequency. Figure shows the radiation pattern of the antenna without slot and shorting wall. There is lack of electric field at the top of the antenna which is not suitable for detecting the tags. Fig6 ... Basic Antenna Theory - Wireless •The radiation pattern of antenna is a representation (pictorial or mathematical) of the distribution of the power out-flowing (radiated) from the antenna (in the case of RADIATION PATTERN OF PATCH ANTENNA WITH SLITS
