Slots A novel printed Yagi-Uda antenna fed by balanced microstrip line is proposed. All the active dipole, reflector and director are printed on the same side of a dielectric substrate. The feeding line printed on the same side with the dipole is directly connected to one of active dipole's branches, while the other feeding line is printed on the other side and connected to another branch through...
A novel T-type fractal boundary wide-slot broadband circularly polarized printed antenna for L-band applications is proposed. The T-type fractal boundary wide-slot is fed by a L-shaped metal microstrip, and the broadband CP is obtained by co-acting of the L-shaped metal microstrip and the T-type fractal boundary. This antenna is designed by simulations and experiments. And results show that the impedance...
Slots which are parallel with the bottom side are loaded at the two equilateral sides of the monopole isosceles triangle printed antenna to achieve multi-band in the operating frequency. The antenna is simulated by CST MICROWAVE STUDIO®, a 3-dimentional full wave electromagnetic simulation software, the simulated results indicate that the central frequency of the pass-band, as well as the bandwidth...
