A broadband printed angled-dipole array antenna is presented in this communication. The printed two-element dipole array is fed by an adjustable integrated balun to maintain the broadband performance. The measured results show that the proposed antenna achieves 39.5% of banwidth, and stable radiation pattern with a peak gain of 4.42dBi–6.33dBi over the operating band. With the proper 45°angle of dipole...
A novel dual-polarized dielectric resonator antenna fed by bowtie-shaped slots is investigated, which exhibits high isolation of greater than about 40dB with a broad bandwidth of wider than 26%. Its measured maximum gain is 6.65dB with a gain variation of 1.25dB over the bandwidth. Its good polarization purity and broadside radiation patterns are also confirmed.
In this article, a circularly polarized (CP) dielectric rod antenna (DRA) is proposed and analyzed. Based on the analysis results, a CP rod antenna is designed and fabricated. The reflection, polarization, and radiation characteristics of the antenna are studied. A good agreement between the simulated and measured results is achieved, and a measured return loss of greater than −10dB is obtained over...
A high-efficiency microstrip-fed angled-dipole antenna has been developed. The printed dipole with an integrated balun features a broad operating bandwidth. The simulation of the antenna show that 7.4–10.5GHz band with VSWR less than 2 is obtained, and gain is more than 4.8dB. With choosing the proper dipole arms angle and with a radome, we can get the widest E-plane and H-plane beamwidth. Comparing...
