“…The simulated cross-polarization is extracted from φ = 45°cut after aligning the Cartesian coordinates with the main beam's direction. This is done to capture the maximum cross-polarization [32]. An attempt to capture both E-plane and H-plane of the measured results is done by compensating for the beam tilt.…”

“…5 shows the co-polar and the cross-polar radiation patterns at (φ = 45 • ) for four different frequencies using Ludwig III definition. The 45 • cut has been chosen because it shows all the radiation pattern information and according to the Body of Revolution (BOR) theory, the peak level of cross-polarization is at 45 • [25]. Therefor, the whole radiation pattern of the desired antenna can be reconstructed from 45 • cut in E and H plane.…”

A wideband differential fed patch antenna with high cross-polarization discrimination is proposed at mm-wave range. For the purpose of increasing antenna bandwidth, capacitive coupling technique is used. Also, the differential feeding is utilized to ensure broadside radiation and low cross-polarization. The designed antenna has an ultra-wide bandwidth of 55% around 30 GHz with S 11 ≤ −10 dB, and a peak gain of 8 dBi. The radiation pattern has a cross polarization level less than −20 dB over the operating frequency band. The differential feeding technique depends on equal power division and 180 • phase difference for all the antenna bandwidth. Due to the wide bandwidth of the differential feeding antenna element, two designs of the feeding circuits (which include rat race and probe strip line transition) are used to cover the whole frequency band of the antenna. A gain enhancement has been achieved by adding a horn to the designed antenna with an efficient aperture efficiency. The designed antennas have fractional bandwidths of 28.73% (at center frequency 25.64GHz) and 26.3% (at the center frequency 32.2 GHz), for the lower and the upper bandwidths, respectively. An average gain of 14.5 dBi has been achieved for the frequency band from 21.8 GHz to 36.5 GHz. The antenna performance is verified through fabrication and measurement, where the simulated and measured results are in a good agreement. INDEX TERMS Law cross polarization, differential feeding, wide band antenna, and hybrid antenna.

In this work, a novel computer‐aided design methodology for probe‐fed, cavity‐backed, stacked microstrip patch antennas is proposed. The methodology incorporates the rigor of a numerical technique, such as finite element methods, which, in turn, makes use of a newly developed procedure (multipurpose admittance matrices) to carry out a full‐wave analysis in a given structure in spite of certain physical shapes and dimensions not yet being established. With the aid of this technique, we form a training set for a neural network, whose output is the desired response of the antenna according to the value of design parameters. Last, taking advantage of this neural network, we perform a global optimization through a genetic algorithm or simulated annealing to obtain a final design. The proposed methodology is validated through a real design whose numerical results are compared with measurements with good agreement. © 2008 Wiley Periodicals, Inc.
