The cost and installation space. As a result, a dual-polarized antenna with a wide band of 1.71–2.69GHz is important for wireless communication systems. Different kinds of dual-polarized antennas have been proposed by antenna researchers, including crossed dipole antennas in 2,3, patch antennas in 4,5, and slot antennas in 6,7. Abstract—A new design for a wideband dual-polarized aperture-coupled patch antenna with dumbbell shaped coupling slots is presented. The printed antenna consists of two stacked patches and an aperture slotted ground plane which is excited using a microstrip line feed. A two-slot dual polarized antenna with a. Abstract: A compact wideband dual-polarized slot-coupled stacked patch antenna is presented in this communication. Two orthogonal U-shaped feed lines are used to excite a cross-slot to obtain dual-polarization. The cross-slot consists of two orthogonal slots whose long sides vary as exponential curves. We developed wideband dual-polarized Tapered Slot Antenna operating at 0.65-9GHz. Single element of TSA is larger than the previously designed one in other researches, but developed antenna covers low frequency. It needs simple feeding network, and the number of divider can be small and insertion loss is a little.

A Wideband Dual-polarized Slot Antennas

Abstract

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.
