*Dual-polarized Slot Antenna For Millimeter Waves Wave
*Dual Polarized Slot Antenna
For the most common dual-polarized Vivaldi antenna shown in Figure 6 (a), in order to avoid the feeding lines overlapping each other, Vivaldi 2 is ahead of Vivaldi 1 with mm. Based on the parameter study of, which is the distance between Vivaldi 2 and Vivaldi 1, the isolation between two antenna ports is shown in Figure 7 (a).
*The design, fabrication and performance of mixers and components for low noise dual-polarized and balanced receivers at millimeter and submillimeter wavelengths both in quasi-optical and waveguide con gurations. The quasi-optical receiver utilizes a novel cross-slot antenna on a silicon hyperhemispherical lens, two junction tuning.
*Index Terms — millimeter wave, waveguide slot array, dual polarization, orthomode transducer, 40GHz 1. Introduction A dual-polarized corporate-feed waveguide slot array antenna was proposed and fabricated as a low-profile high-efficiency planar antenna for effective frequency reuse in the 60 GHz and 120 GHz bands 1 2.

A new technique for designing wideband dual-polarized cavity-backed slot antennas is presented. The structure is in the form of a double-resonant, dual-polarized slot antenna backed by a shallow substrate integrated cavity with a depth of approximately one tenth the free space wavelength. The presence of the cavity behind the slot enhances the antenna’s directivity and reduces the possibility of surface wave propagation in the antenna substrate when the element is used in an array environment. Moreover, the dual-polarized nature of this radiating element may be exploited to synthesize any desired polarization (vertical, horizontal, RHCP, or LHCP). The double-resonant behavior observed in this substrate-integrated cavity-backed slot antenna (SICBSA) is utilized to enhance its bandwidth compared to a typical cavity-backed slot antenna. A prototype of the proposed antenna is fabricated and tested. Measurement results indicate that a bandwidth of 19%, an average gain of 5.3 dB, and a wideband differential isolation of 30 dB can be achieved using this technique. The principles of operation along with the measurement results of the fabricated prototype are presented and discussed in this dissertation. The SICBSA is investigated as a candidate for use as an array element. A uniform two element phased array is demonstrated to locate the main beam from boresight to thirty degrees. The potential effects of mutual coupling and surface wave propagation are considered and analyzed.Notes
