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...
A planar complementary magnetic-electric dipole antenna structure is proposed. The proposed antenna is composed of a folded dipole antenna and a periodical capacitive loaded loop antenna. The current along the periodical capacitive loaded loop is uniform in amplitude and phase, therefore, the loop antenna is equivalent to a magnetic dipole, the radiation pattern of which is complementary to that of...
A novel conical horn antenna loaded with ball cone dielectric is designed in this paper. The design method of the dielectric surface equation is given. The comparison between the smooth wall conical horn antenna and the four types of horn antennas, the dielectric lens-corrected horn antenna, the dielectric loaded horn antenna, the cone dielectric loaded horn antenna, and the ball cone dielectric loaded...
This letter presents the design of a novel wideband horizontally polarized omnidirectional printed loop antenna. The proposed antenna consists of a loop with periodical capacitive loading and a parallel stripline as an impedance transformer. Periodical capacitive loading is realized by adding interlaced coupling lines at the end of each section. Similarly to mu-zero resonance (MZR) antennas, the periodical...
A high gain hybrid monopole-dielectric resonator antenna is introduced. By loading a half-ring-shaped dielectric resonator over a monopole element in the vertical plane, two high-order modes are excited in the DR together with the self resonance of the monopole antenna. The achieved −10dB impedance bandwidth is 25%, covering the frequency range of 5.88 to 7.58 GHz. The simulated gain is about 7.3...
This paper presents a novel design of compact dual-polarized antenna incorporating an aperture-coupled annular ring patch antenna for left-handed circular polarization (LHCP) as well as a disk-loaded monopole vertical polarized (VP) antenna. Both antennas operate in the same frequency range from 2.320GHz to 2.345GHz, while CP antenna reveals good broadside radiation patterns and the VP antenna shows...
