“…Recently, for the planar configuration; substrate integrated waveguide (SIW) technology serves as an outstanding and prominent candidate for microwave and millimeter‐wave based applications, which provides miniaturization, low insertion loss, minimum mutual coupling, high isolation level and low cross‐polarization with stable gain as compared with multilayer geometry, EBG and defected ground structures. So, now a day SIW based cavity‐backed self‐triplexing antennas introduced as the most emerging topic for researchers. Kumar and Dwari introduce a SIW based self‐triplexing antenna having bow‐tie‐shaped slot with two microstrip feed lines and a coaxial feed, which is not suitable for planar configuration .…”

A planar substrate integrated waveguide (SIW) based cavity‐backed self‐triplexing slot antenna is proposed for X‐Ku band applications. The antenna comprises of the SIW cavity, radiating slots, and feeding networks. The radiating slots; that are etched on the upper metallic plane of the SIW, are backed up by the three radiated quarter cavities (QCs). The radiating slots in the respective QCs are of different lengths, excited by three separated orthogonal feed lines to resonate at three different frequencies as 11.01, 12.15, and 13.1 GHz. By fine‐tuning the antenna parameters, an intrinsic input port isolation of better than 26 dB is realized which helps in achieving the self‐triplexing property. The behaviors of individual cavity modes at three resonant frequencies are explained with the help of Z‐parameter. The proposed antenna layout is easy to integrate with the planar circuit. The proposed antenna is fabricated and measured results display a close concern with the simulated results. Moreover, a unidirectional radiation pattern and gain of 5.1, 5.54, and 6.12 dBi at resonant frequencies are realized.

This letter presents an improved planar circularly polarized antenna with broad impedance and axial ratio (AR) bandwidths. Four rectangle slots backed by a substrate integrated waveguide (SIW) cavity are fed by a sequentially rotated feeding network to realize the circular polarization. Besides, TE110 and TE210 modes are excited in the SIW cavity and thus an impedance band from 5.24 to 6.44 GHz (20.6%) and an AR band of 5.29 to 6.19 GHz (15.7%) are realized. The antenna also has some other advantages, such as compact size, low profile, and easy integration with other planar circuits, which make it has the potential for some wireless systems.

In this article, a novel design of single layer, compact, multiple input multiple output (MIMO) half-mode substrate integrated waveguide (HMSIW) cavity backed quad element slot antenna with high front-to-back ratio (FTBR) is proposed. The proposed antenna consists of four rectangular SIW cavities with semi-taper radiating slots. The antenna elements are placed in a fashion to achieve high isolation. This antenna is designed for WLAN vehicular communication system to cover the frequency range of 5.84 GHz to 5.96 GHz. It has high front to back ratio (FTBR) of more than 25 dB without using any external metallic reflector. It has more than 37 dB isolation in between orthogonal elements and more than 24 dB in between parallel elements. The envelop correlation coefficient (ECC) and diversity gain are 0.003 and 9.99 dB respectively in between all the elements. Moreover, the antenna has high gain and efficiency of more than 8 dB and 94%, respectively, in 10 dB impedance bandwidth. It can be tuned in a wide range of frequency.
