“…A full-wave moment method code called Monurbs, included in the NewFasant simulation computer suite [18], has been used to carry out the numerical simulations. This code has been validated in many benchmark experiments to check its reliability [19][20][21][22][23], showing high accuracy when comparing with measurements. Fig.…”

A metal‐only Fresnel zone plate antenna (FZPA) to operate at millimetre wave frequency bands is presented in this work. The proposed antenna is a very attractive alternative to parabolic reflectors and reflectarrays because of its several advantages such as low profile, low cost, easy to manufacture and lossless. A centre‐fed Fresnel zone plate whose diameter is 300 mm has been designed and analysed at 75 GHz providing a gain of 44.29 dBi, an aperture efficiency of 48.42% and a cross‐polarised level lower than −40 dB for the diagonal plane (ϕ = 45°). A second prototype has been designed and analysed from 54 to 68 GHz to evaluate the performance of the proposed antenna compared with an already published FZPA.

“…As compared to planar near‐field measurements, a cylindrical near‐field (CNF) measurement has a simpler mechanical structure, and it is more suitable to measure the one‐dimension array with a broad beamwidth in the horizontal ( ϕ ) plane. For traditional CNF measurements, an open‐ended waveguide (OEWG) is often used as a probe to collect the near field samples of the antenna under test (AUT) . However, the OEWG designed at S band is large as well as heavy, and it needs to scan the AUT twice to perform two‐polarization antenna measurements.…”

A cylindrical near‐field antenna measurement using a probe with switchable polarization is described. The probe is a dual‐feed crossed‐dipole antenna with wideband operation, and its polarization can be switched between dual orthogonal linear polarizations by selecting one feed as the signal input port. The system layout for the proposed near‐field antenna measurement is shown. Two S‐band antennas, including a standard gain horn and a 1 × 8 planar array, are respectively selected as the antenna under test, and the radiation patterns obtained from the constructed near‐field measurement system have good agreements with the simulated results. In addition, the use of the polarization reconfigurable probe can eliminate the need of rotating the probe by 90°, and consequently the test time is obviously reduced. © 2016 Wiley Periodicals, Inc.
