“…The high‐frequency applications, mostly preferred transmission line is SIW, other names are laminated waveguide and post‐wall waveguide, and it is one from of substrate‐integrated circuits (SICs), etched two rows of vias connected in top to bottom plane through substrate and also implemented for active, passive components, and antenna due to system on substrate (SOS) technology used to develop. The slot antenna are best suited for wireless communication due to its advantages like less loss, more bandwidth, and low loss compared to other antennas.…”

In this article, a compact SIW‐based H‐spaced head‐shaped slot antenna is proposed, and slot is etched into the top, proposed design printed by RT‐Duriod 5880 substrate (εr = 2.2), which is accountable for achieving millimeter‐wave wireless applications, small size, and broadband operation. The SIW‐based slot antenna with a compacted dimension of 14 × 8 × 0.381 mm3 is fabricated and tested. The testing results show that the design proposed, having occupied frequency range from 58.5 to 61.72 GHz, respectively, covers V‐band (millimeter wireless communications applications). The testing and simulation result bandwidth range of a proposed design is 4.22 and 4.19 GHz. It has fine radiation characteristics for both E‐field and H‐field in all the preferred operational bands and generates superior performances compared to the existing design antenna in the reviews.

2018

This letter presents a slot‐based self‐diplexing MIMO (multiple‐input multiple‐output) antenna for dual‐band operation. In the first step, a self‐diplexing antenna is designed with two microstrip fed quarter wavelength slot‐antenna elements. Next, this self‐diplexing antenna is replicated to obtain the characteristics of a MIMO antenna. The designed self‐diplexing MIMO antenna with optimized dimensions operates at 5.1 GHz and 5.7 GHz. The peak gains obtained at two frequencies are 2.02 dBi and 2.96 dBi. Minimum isolation at both the operating bands is better than 15 dB. The proposed antenna offers a frequency ratio of 1‐1.62.
