“…To measure the materials/radomes at oblique incident angles, the thru response (TR) calibration technique is used. Finally, after each calibration method, time gating technique is implemented to eliminate the effects of the reflections from the system [29]- [31]. Fig.…”

This paper presents an accurate procedure to design, characterize and test a radome for millimeter-wave applications. In this procedure, an accurate analytical model is presented to design a radome structure that takes into consideration the bandwidth, losses, reflections and depolarization factor as a function of frequency and incident angle. To guarantee a good operational electrical performance, the proposed procedure includes a material characterization and accurate test procedure based on the free-space Gaussian beam method and time gating filtering technique. Four radomes (two-monolithic and two A-sandwich) at 82 GHz and 94 GHz are designed, characterized and tested to validate the proposed technique. Results obtained with this procedure are compared with numerical simulations and experimental results. This method is shown to be accurate and versatile for radomes in mm-Wave applications.

“…Also, it is worth noting that, the antenna performance and the accuracy of weather measurement could be affected by radome conditions (e.g., wet radome) and several investigations have been conducted to illustrate these effects on antenna radiation pattern and the polarimetric biases [21]- [23].…”

The design and development of a high-performance, dual-polarization, hybrid aperture-coupled microstrip patch antenna are presented. In the presented design, the horizontal and vertical polarizations are excited using the aperture coupling method. The isolation level of better than 51 dB and cross-polarization level of less than −30 dB are achieved from the measurement results of the designed single element. To achieve better cross-polarization levels, the 2 × 2 element subarrays of the proposed unit cell, while the horizontal polarization ports are mirrored, are designed and fabricated, and a lower than −39-dB cross-polarization level is achieved in the measurement results. Finally, to characterize the scan performance of the unit cell and subarray, a 4 × 10 element array of the proposed single element is fabricated and a better than −45-dB cross-polarization level is observed while scanning up to 45 •. INDEX TERMS Dual-polarized, aperture coupled, high isolation, array antenna, differential feed, phased array radar, cross-polarization suppression, image arrangement.
