“…The modern wireless communication system requires the multi-band antenna with better performance and high isolation between the ports in several applications (Mahant et al, 2020;Vala and Patel, 2020;Chen et al, 2008;Nandi and Mohan, 2017;Mukherjee and Biswas, 2016;Chaturvedi et al, 2018). The overall volume of the microwave system mainly depends on the size of passive components such as antenna, diplexer, filters and other elements.…”

“…It demands the design and development of multi-band microwave components, and one of the requirements is the development of dual-band antennas. To reduce the necessity of a diplexer in RF transmitter and receiver block, diplexer and triplexer antennas are proposed by various researchers (Vala and Patel, 2020;Chen et al, 2008;Nandi and Mohan, 2017;Mukherjee and Biswas, 2016). As it eliminates the requirement of the diplexer, it reduces the size of the RF system as well as the development cost.…”

Purpose The purpose of this paper is to design and develop half-mode substrate-integrated waveguide (HMSIW)- and quarter-mode substrate-integrated waveguide (QMSIW)-based antennas for wireless communication application. The developed antennas offer advantages in terms of compactness, high gain and better isolation between the ports. Design/methodology/approach Initially, the tri-band substrate-integrated waveguide-based antenna is designed using a slot on the ground plane. Then, the same structure has been bisected into two parts for the development of the HMSIW structure. Again the concept of the slot is used for the realization of a dual-band antenna. QMSIW-based structure is designed with further dividing HMSIW structure into two parts. Simulation has been carried out with the use of a high-frequency structure simulator (HFSS) software, which used a finite element-based solver for the full-wave analysis. Findings The proposed HMSIW-based dual-band antenna resonates at two different frequencies, namely, 5.81 GHz with 4.5 dBi gain and at 6.19 GHz with 6.8 dBi gain. Isolation between two ports is 20 dB. The overall dimensions of the proposed model are 0.39 λ × 0.39 λ. Similarly, QMSIW-based antenna is resonated at 5.66 GHz of the frequency with the 3 dBi gain. Frequency tuning is also carried out with the change in the slot dimension to use the proposed antenna in various C (4–8 GHz) band applications. Originality/value The proposed antennas can use C band wireless frequency application. The proposed structure provides better performance in terms of isolation between the ports, small size, high front-to-back ratio and higher gain. It is fabricated for the proof of concept with the RT Duroid 5880 substrate material having a 2.2 permittivity. Measured results show a similar kind of performance as a simulated one.
