“…Increasing the electrical thickness of the substrate using the concept of dielectric resonator antennas (DRA) helps to minimize the reflectance response 39 . The addition of superstrate layers over the patch region helps optimize the fringing effect, which tends to affect the reflectance response 40 . In Sumathi et al, 12 the varying dielectric constant is identified by changing the material.…”

Summary The proposed work represents a simple and effective approach to achieve frequency tunability. The tunability is attained by the switching mechanism of the two PIN diodes. The biasing issue is reduced due to the usage of two PIN diodes. Simulation is carried by a high‐frequency structure simulator tool and compared with the fabricated structure for the authentication. Antenna fabrication is performed by low‐profile material FR‐4. Three modes were analyzed and compared in terms of resonating frequency, reflectance response, gain, bandwidth, and electric field based upon switching of PIN diodes. The proposed antenna structure provides a multiband response with the four frequency tunable bands along with maximum frequency tunability of 700 MHz and a minimum reflectance response of −28.22 dB. The proposed structure opens a new door of applications like satellite communication, military, and a sensor for the S, C, X, and Ku bands. The presented design was also compared with the previously published papers to identify the improvement.

The manuscript represents a novel superstrate metamaterial loaded microstrip patch antenna to achieve multiband frequency reconfigurability. The performance is observed for the frequency band of 4 to 8 GHz. Metamaterial property is enabled by engraving triangular-shaped split-ring resonators in the substrate. Frequency tunability is achieved based on the switching mechanism of three PIN diodes. Different materials are loaded in the split ring resonators like copper, distilled water, and seawater for the performance observation in terms of reflectance response, Bandwidth, gain and tunability. The design provides the reflectance response of À43.38 dB, Bandwidth of 220 MHz, and frequency tunability of 100 MHz. The proposed design is also giving the highest gain of 8.3 dB. The structure is fabricated using FR-4 to reduce the overall cost of the antenna, and it is tested using a vector network analyzer and anechoic chamber. Simulated results and fabricated ones are compared for reliability. The proposed design, with its flexible and reconfigurable capability, can be applicable in IoT applications.

A rotating magnet-based mechanical antenna (RMBMA) is a new promising paradigm which can significantly reduce both the size and the power consumption of the super-low frequency electromagnetic transmitter. To further reveal the effects of the rotational motion on transmission, this paper investigates the performance analysis of MSK (Minimum Shift Keying)-based RMBMA for the first time. Initially, based on the framework of MSK-based RMBMA, both the information loading of RMBMA and the control strategies of the motor are proposed, such that the impacts of the step response induced by the motor on the information loading are characterized. Then, the transmission capacity of the MSK-based RMBMA is derived in the closed form. The results indicate that increasing output torque or decreasing inertia load can enhance the transmission capacity. Finally, numerical simulations using a realistic system model demonstrate the validity of the proposed performance analysis. The simulation results show that when the inertia is less than 0.0128 kg∙m2 and the symbol rate is less than 4 bit/s, the bit error rate is less than 10%, thereby improving the transmission capacity. The proposed comprehensive design principles of RMBMA provide guidance for system design and practical implementation.
