“…A few conventional designs have utilized rat-race couplers in conjunction with an antenna to achieve self-interference cancellation. However, this approach either results in interconnection complexity or the fourth port being dormant [2,17]. In contrast, the proposed SIW power combiner directly interconnects with the antenna simplifying the design considerably.…”

“…Achieving higher SiC in propagation domain can relax the requirements down the transceiver's chain and has been a focus of recent research [2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17]. One approach utilizes ferrite based circulators to isolate the Tx and Rx; however, they are non-planar and thereby, not aligned with today's miniaturization requirements [14].…”

“…One approach utilizes ferrite based circulators to isolate the Tx and Rx; however, they are non-planar and thereby, not aligned with today's miniaturization requirements [14]. Microstrip based planar antennas and circuits constitute the second more common approach; however, most reported designs are limited to sub 6 GHz bands [2,16,17]. Moreover, the contradicting requirements of substrate permittivity for antennas and adjoining cancellation circuits further complicate the design and are prohibitive at mm-wave frequencies.…”

In-band full duplex offers a new approach of meeting the ever-increasing data rate demands by operating the transmitter and receiver at the same frequency at the same time, potentially doubling the spectral efficiency. However, self-interference is the fundamental bottleneck of such systems. In contrast to non-planar or sub 6 GHz microstrip designs reported so-far, this paper presents an all SIW based antenna system for in-band full duplex systems. The proposed design integrates a dual linear polarized three port differential antenna, three port SIW common-mode power combiner and a 180°phase shifter at 28 GHz. Operating the antenna in TE201 mode provides inherent isolation between the differential receive and single-ended transmit port. The residual coupling is further reduced through use of TE101 based power combiner and a 180°phase shifter. Implemented on a 0.508 mm thick RT Duroid 5880 substrate, the antenna occupies a foot-print of 48 × 80 mm2. Demonstrating a measured gain of 6.95 dBi and 3.42 dBi for Tx and Rx mode of operation, respectively, the proposed design offers a self-interference cancellation (SiC) of better than 36 dB over a 177 MHz bandwidth.

“…1 The novel orthomode transducer is integrated in SIW horn antenna and TE 01 and TE 10 modes are generated by feeding different ports to achieve dual-polarization. 2,3 In, 4 patches are placed at the inner space between two parallel coupled microstrip feedlines. When phases on the two feedlines are same or opposite, vertical linear polarized wave (VLP) and horizontal linear polarized wave (HLP) can be generated.…”

This article presents a 37 GHz compact patch antenna array which can generate dual-linear-polarization (LP) from a single radiating aperture for mm-wave applications. The antenna adopts dual-layer structure to achieve miniaturization and also to design the feeding network. The substrate integrated waveguide (SIW) feeding network is built in the bottom layer. On the top layer, multi-strip ±45 polarized series-fed patch subarrays are fabricated. Patches with variable width and two eight-way unequal power dividers are employed to suppress the sidelobe level (SLL) in two planes. A 90 3 dB coupler with a 90 electric length of SIW is adopted to realize same phase and opposite phase.Thus, two polarized waves, namely vertical linear polarized wave (VLP) and horizontal linear polarized wave (HLP) can be generated. Finally, a prototype SIW patch antenna array is fabricated. The antenna gain is about 24-25 dBi for both VLP and HLP and SLL is under -12 dB in the frequency range of 36.5-37.5 GHz.

A novel dual-polarization edge-fed microstrip patch antenna was designed in this letter. In order to increase the isolation between the two ports with different polarizations and reduce the working modes affected by the feed line, two-section continuous current strips were separated from the metal ground plane. The measured result shows that the antenna has a port-to-port isolation better than 28.9dB from 5.725GHz to 5.875GHz, and particularly better than 32.6dB at 5.8GHz, which is improved more than 12dB compared with traditional antennas. Besides, a dual-polarization excitationcan be realized within the single patch antenna for a single layer dielectric structure.
