Abstract :
A novel focusing lens conical horn antenna loaded with dielectric is designed in this paper. The design method of the dielectric surface equation is given. The comparison between the proposed antenna and traditional spot focusing lens antenna is well discussed. Simulations show that the proposed antenna has advantages of small reflection, low cross-polarization, symmetrical beam, and small focal spot. The antenna can be obtained very symmetrical focal spot. What´s more, the focal spot is approximately circular. The average electric field strength at the focal point of the antenna can be improved by about 1/dBVm than traditional spot focusing lens antenna. This article provides a new focusing lens antenna design ideas, with good reference value.
