Substrate Integrated Waveguide Cavity Backed Slot Antennas (SIW CBSA) are emerging candidates for planar Integrated Circuit (IC) technology in Millimetre-wave (MMW) bands. This peculiar antenna holds the advantage of conventional metallic cavity-backed antennas, with high gain, high front-toback ratio, and low cross-polarization level. SIW CBSA structures are the best option for planar integration with a low profile, and low fabrication cost in the design of MMW systems. This paper discusses various forms of SIW CBSA structures, their operating mechanism, and methods of improving their performance in terms of gain, bandwidth, size reduction, beamforming capability, and multiple bands of operation. From this discussion, we can select the antenna with the required characteristics in terms of gain, dual-band, and dualpolarization suited for present and future-generation applications.

The design of an equilateral triangular slot-based planar rectangular antenna is presented for wideband millimeterwave (mm-wave) applications. The front-side of the proposed antenna is composed of a rectangular patch radiator with an equilateral triangular slot fed using a 50Ω microstrip feeding line, while the bottom side of the antenna consists of a partial ground plane. To achieve maximum impedance matching in the operating bandwidth, the position of the feeding line is shifted from its normal location. The overall dimensions of the antenna are noted to be 6.5×8.5 mm 2 . From the simulation results, it is demonstrated that the -10 dB impedance bandwidth of the proposed antenna is 16.86 GHz, ranging from 22.28 GHz to 39.14 GHz, while at -15 dB, it is equal to 12.82 GHz in the frequency range of 24.18-37 GHz. The gain of the proposed antenna fluctuates in the range of 3.89-6.86 dBi with an antenna efficiency of >85%.

“…If the variation in amplitude and phase caused by temperature drift exceeds a certain value, the transmission quality of the signal will decline, leading to large errors. Moreover, at high frequencies, microwave resonant cavity suffers from low gain, poor radiation efficiency and narrow bandwidth [15,16]. Therefore, it is of great necessity to enhance the temperature performance of the resonant cavity [17].…”

Resonant frequency varies significantly due to temperature changes for microwave resonant cavities. Hence, temperature robustness enhancement is of great importance. In this paper, a resonant cavity with enhanced temperature robustness is proposed by applying the dual-material strategy to the middle cavity. Compared to the single-material cavity, the dual-material cavity can demonstrate better temperature robustness with a decrease of 72.7% in the frequency shift over the temperature range of −20 to 80°C. Moreover, the |S11| < −10 dB impedance bandwidth is 6.3% (3.39–3.61 GHz) and the gain is 20.4 dBi at 3.5 GHz for the manufactured dual-material cavity, which are much better than those of the manufactured single-material cavity. Finally, an experiment is conducted to measure the resonant frequencies with the sample solution tube of the dual-material cavity filled with nothing or 30 mg/dl CuSO4 solution, the measured values are consistent with the simulated ones. The influence of temperature drift is significantly reduced, and the feasibility of the dual-material strategy is verified.
