“…Further crossed dipole configurations for dual band operation at 26/ 28 GHz and MIMO operation at 28 GHz have been proposed for SICL in [15] and [16]. Studies on SICL based slot antenna arrays at mmWave frequencies to generate unidirectional [17] and bidirectional [18] beams are also reported. In this paper, we propose a simple passive approach to design an In-Band Full Duplex (IBFD) antenna using novel HMSICL cavity fed monopole antenna at 28 GHz.…”

In this paper, we propose a novel Half Mode Substrate Integrated Coaxial Line (HMSICL) cavity fed monopole antenna at 28 GHz. A SICL cavity is bisected along its symmetric magnetic wall (PMC) to create an open-ended Half Mode SICL (HMSICL) cavity. The proposed HMSICL cavity is used to excite a tapered monopole antenna to radiate in endfire direction with a gain of 6.4 dBi at 28 GHz. For dual beam application, it is integrated with unidirectional broadside Half Mode Substrate Integrated Waveguide (HMSIW) antenna exhibiting a gain of 5.1 dBi that provides spatial diversity to the proposed design. To achieve high gain, two co-located 1 × 4 linear HMSICL and HMSIW array are placed sideby-side such that the proposed design produces simultaneous endfire and broadside beams for In-Band Full Duplex (IBFD) applications. The proposed passive Signal Interference Cancellation (SIC) technique is utilized to minimize the overlap of simultaneous dual beam at 28 GHz by orienting the two antennas within a compact footprint. The full duplex antenna array achieves a gain of 10.8 dBi in endfire and 10.3 dBi in broadside direction with high isolation below 45 dB over 500 MHz bandwidth. The presented antenna array is a potential candidate for relay where the transmitting and receiving signals are in two different directions.

Communication in urban cities is possible through an efficient multi-hop link between Non-Line-of-Sight (NLOS) end-users. Relays with simultaneous dual beam establish a communication link between two end users for NLOS communication [1] as shown in Fig. 1. An In-Band Full Duplex (IBFD) antenna array used in streetlight deployment and over building is the upcoming easy cost-effective solution for deployment in Ka-band for faster Vehicle-to-Vehicle communication. However, IBFD antennas have been regarded impractical in the past due to the strong Self Interference (SI). Several active and passive suppression techniques such as passive suppression through antenna isolation, active suppression via analog and digital cancellation [2] have been proposed to compensate for self interference. The basic passive suppression technique is the physical separation of the

In this Letter, a novel compact slot antenna has been realised using substrate integrated coaxial line (SICL) cavity. SICL technology helps to achieve cavity size of 0.41λ0×0.48λ0 while maintaining its inherent advantage of self shielded and low loss transmission line at millimetre frequencies. A SICL cavity is designed by shorting the middle conductor at the two edges and keeping the other two edges separated from the sidewall. The eigenmode analysis affirms the presence of a dominant TEM mode at 28 GHz along with the presence of SICL even and odd modes. A half wavelength diagonal slot is etched on the bottom plate of the cavity to disturb the TEM mode surface current at 28 GHz. Measurement results show the SICL cavity backed slot antenna exhibits a gain of 5.6 dBi at 28.6 GHz and high front‐to‐back ratio better than 17 dB. The SICL‐based cavity exhibits millimetre wave resonance with much smaller size, which helps to improve the compactness of the design. The proposed antenna can be used for millimetre wave applications like handheld mobile devices at millimetre‐wave frequencies.
