Design of Monopulse Radial Line Slot Antennas Manuel ... Abstract: The authors propose the design of one radial line slot antenna with two simultaneous beams, one broadside beam and one conical beam. The antenna is a radial line slot antenna, with the slots placed on the upper plate in concentric rings. The radiation element is a slot pair, designed for getting left hand circular polarization. 23PM2B-04 Study of a High Gain Radial Line Slot Antenna in ...

A Reconfigurable Radial Line Slot Array Antenna for WiMAX Application 55 achieves a higher gain in comparison to the divisive broadside pattern. Figure 8 depicts the 3D simulation of the far field radiation patterns of the proposed antenna which is aligned with the measured radiation patterns as shown in figure 6 and figure 7. However, the

Each antenna element is preferably a dual polarization octagonal patch antenna element disposed on a common surface of the antenna aperture layer. Antenna (radio) - Wikipedia The end result is that the resonant antenna will efficiently feed a signal into the transmission line only when the source signal's frequency is close to that of the design frequency of the antenna, or one of the resonant multiples. Dipole antenna - Wikipedia In radio and telecommunications a dipole antenna or doublet [1] is the simplest and most widely used class of antenna. [2] [3] The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary … Antenna Calculators : Antenna design calculators - The DXZone…
