Radiation mechanism of slot antenna

By Guest

circular disc antenna oﬁers narrow bandwidth, an oﬁset microstrip-fed line is used and a strip is inserted at the radiating edges in the circular slot patch to enhance the wideband characteristics of the slot antenna. The proposed slot antenna greatly demonstrates to cover the widebands of UHF and microwave for RFID application. 3.

I am a beginner. Can anyone suggest me materials to refer, to understand the radiation mechanism of microstrip antenna. I have tried some materials but couldnt understand better. Integrated Solar Panel Antennas for Small Satellites typical radiation pattern and return loss for slot antenna is shown in Fig.3 and 4 respectively. It is seen that the slot radiates in both planes (both sides of the PEC). Fig.2: Slot antenna and its complementary dipole. Fig.3: Radiation pattern from a slot antenna. Fig.4: Resonance frequency of 2.4 GHz slot antenna. RESONANT LENGTH CALCULATION AND RADIATION PATTERN SYNTHESIS ...

If the slot antenna is superimposed on its complementary dipole antenna structure, one would obtain an infinite conducting plane. Interestingly, employing certain symmetry in Maxwell's equations and realizing the complementary nature of the above two structures, it can be shown that the fields of a...

Written by: Vishal Bhavsar Nicholas Blas Huy Nguyen Under the Guidance of: ProfessorAntennas are a fundamental component of modern communications systems. By definition, an antenna acts as a transducer between a guided... Radiation Characteristic Improvement of X-Band Slot … International Journal of Antennas and Propagation is a peer-reviewed, Open Access journal that publishes original research articles as well as reviewThis shows that the FSS screen is like a good reflector to the slot antenna inside the X-band. Here, the simulated radiation efficiencies (as well as...

enter the antenna and have associated with them electric charges and corresponding currents. If we remove part of the antenna structure, as shown in Figure 1.11 (b), free- (a) Antenna and electric field lines (b) Antenna and free—space wave ø Figure 1.11 Source, transmission line, antenna, and detachment of electric field lines.

Slot antenna - Wikipedia Slot 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 microwave frequencies instead of line antennas when greater control...
