Slot Microstrip Antenna for 2.4GHz RFID Reader Application

Microstrip Antenna - an overview | ScienceDirect Topics Return loss and radiation pattern are measured with the microstrip antenna as the receiver and shown in Figures 10.34 and 10.35, respectively. A transmitter made of traditional dipole antenna is used and the transmitter–receiver distance is 42 m. The radiation pattern and … Wideband Radiation Reconfigurable Microstrip Patch Antenna Wideband Radiation Reconfigurable Microstrip Patch Antenna Loaded With Two Inverted U-Slots Abstract: A wideband rectangular microstrip patch antenna with reconfigurable radiation patterns is proposed in this paper, which contains two symmetrically inverted U-slots, and incorporates two coaxial probes along the resonant length of the patch.

diodes are used to control the radiation pattern of a planar annular slot antenna keeping constant the operation frequency. II. DESIGN CONCEPT The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line,

Antenna Theory - Radiation Pattern - tutorialspoint.com Radiation is the term used to represent the emission or reception of wave front at the antenna, specifying its strength. In any illustration, the sketch drawn to represent the radiation of an antenna is its radiation pattern. One can simply understand the function and directivity of an antenna by Design of Circular Micro strip Patch Antenna with - ijert.org

The radiation pattern of the Slot antenna is Omni-directional, just like a half-wave dipole antenna. Take a look at the following illustration. It shows the radiation pattern of Slot antenna drawn in Horizontal and Vertical planes respectively

Design And Analysis Of Compact U Slot Microstrip Patch 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. Antenna Theory - Slot - Tutorials Point The terminal impedance is quite desirable for the radiation. Radiation Pattern. The radiation pattern of the Slot antenna is Omni-directional, just like a half-wave dipole antenna. Take a look at the following illustration. It shows the radiation pattern of Slot antenna drawn in Horizontal and Vertical planes respectively. Advantages Antenna Theory - Micro Strip - tutorialspoint.com
