The simulation in wide frequency band is tremendously faster if at each frequency the model is meshed again, and the number of unknowns is adjusted owing to special feature.
The built-in interpolation allows to simulate return loss with minimum number of frequency points. Design of the Sierpinski antennas is based on the Sierpinski triangle — a well-known planar fractal.
The Sierpinski antennas are commonly used in applications where operation at multiple frequencies is required. They can be easily fabricated with conventional printed circuit technology and found in cell phones and various Wi-Fi devices.
The simulation was done at regular desktop PC in just a couple of seconds per frequency point. The frequency range is from 0. The comparison of the measured and simulated return loss confirm excellent accuracy.
The model of hyperboloidal lens illuminated by choke horn antenna was successfully designed and simulated using WIPL-D Pro. Process of modelling includes using WIPL-D Pro built in objects, which ensures the optimal required number of unknowns.The presented results show that the XETS is a very good antenna candidate for UWB applications, being very compact (lambda0 times lambda0) where lambda0 is the lower bound of the frequency band, very stable radiation pattern and polarization for all observation angles and high output pulse fidelity. A compact printed antenna is described that exhibits adequate transient performance for ultrawideband (UWB) applications and it is further adequate for polarization diversity schemes. The antenna is based on an original combination of two crossed.

Such approach makes easier the modelling tapered and speeds up simulation. The radiation pattern of free space epxonentially horn was compared to the lens antenna, exponentially showing the focusing.
The effect is crossed shown by calculating the near field in front and after the lens. All simulations were carried out in several seconds at inexpensive desktop PC. Antenna design of dual-band antenna seems to be irreplaceable part of any Slot system.
UWB Crossed Exponentially Tapered Slot Antenna with WLAN Band Rejection
The antenna represents slot loaded microstrip patch antenna with coaxial feed. The result reveals S-parameter which is lower than dB in the L1 and L2 bands. The simulation with the default numerical kernel settings is done at rather low number of frequency points, due to built-in interpolation.Their combined citations are counted only for the first article. Performance of a crossed exponentially tapered slot antenna for UWB systems. JR Costa, CR Medeiros, CA Fernandes Compact tapered slot UWB antenna with WLAN band rejection. CR Medeiros, JR Costa, CA Fernandes. IEEE Antennas and Wireless Propagation Letters 8, The presented results show that the XETS is a very good antenna candidate for UWB applications, being very compact (lambda0 times lambda0) where lambda0 is the lower bound of the frequency band, very stable radiation pattern and polarization for all observation angles and high output pulse fidelity. One such antenna, a very compact printed planar slot-based UWB antenna has been previously presented. It is a balanced configuration that exhibits excellent spatial polarization and radiation pattern stability versus frequency. It is referred as the crossed exponentially tapered slot antenna (XETS).Cited by: 1.
It was carried out at regular desktop PC, eliminating any need for expensive workstations. At low frequencies, outer rings resonate, while at high frequencies the inner rings are resonant. At microwave frequencies coaxial cable unbalanced waveguide are most commonly used feeders.
Here we need balun to transform twpered input signal from unbalanced to balanced mode. Printed balun microstrip technologyis placed below the planar sinuous antenna.
We analyze two different baluns: Exponential and Klopfenstein taper. They yield return loss under dB in extremely wide frequency band. For the EM simulations, we use a regular desktop computer. The simulation was carried out at only 16 frequency points owing to the efficient built-in interpolation.
