“…Apart from this, a defected structure [7][8][9][10][11][12][13][14][15][16][17] is considered on patches and grounds for effective and simple methods to miniaturize the antenna size and to attain additional resonant modes. A crescent-shaped planar monopole antenna 7 is proposed with defected ground structure (DGS).…”

“…The corrugated Y‐shaped patch antenna 15 operates for triple band with enhanced gain. An ultra‐miniaturized tunable slot‐based antenna 16 was considered to operate the antenna for IoT application. A miniaturized triband antenna 17 with a meander shape line and inverted G‐shape is added to the patch and a rectangular slit is considered on ground plane to attain the triband frequencies.…”

The investigation of two half circular patch (HCP) antenna with defected ground structure to operate dual bands is presented in this study for wireless communications. The crescent slots etched on the HCPs are proposed to operate the dual bands of below −10 dB reflection coefficient, with the impedance bandwidth of the first band being 740 MHz (3.01–3.75 GHz) and of the second band being 7120 MHz (6.74–13.86 GHz). The proposed HCP antenna was resonates of 3.36 and 12.17 GHz with −33.9 and −35.47 dB reflection coefficients. This antenna produces a maximum gain of 5.46 and 6.61 dB for these resonating frequencies, respectively. The simulation and measured radiation pattern results are also presented for proposed HCP antenna and it operates for wireless communications and internet of things applications.

Tunable SIW-Based Evanescent-Mode Cavity-Backed Slot Antenna With Contactless Tuning

et al. 2023

This paper presents a frequency reconfigurable evanescent-mode cavity-backed slot antenna (ECBSA) with a wide tuning range, high-power handling capability, and simplified manufacturing. The tuning mechanism consists of external long-range linear actuators and a contactless tuner disc to vary the capacitive loading of an evanescent-mode cavity. The antenna's operating frequency is tuned by changing the cavity's critical gap size. Radiation occurs through an annular slot aperture on the cavity's ground plane. The design is realized on a printed circuit board (PCB) using substrate-integrated waveguide (SIW) technology to facilitate easier system integration with other planar circuits. The fabricated prototype of the antenna shows 40% tuning from 1.71-2.58 GHz when the contactless tuner is displaced vertically across a distance of 508 µm. Measurement results for the peak realized gain of ECBSA is as high as 5.48 dB at the maximum operating frequency of 2.58 GHz. Due to a larger range of the cavity's critical gap sizes, achieved using external linear actuators, the power handling capability is higher than the typically used piezoelectric disk tuners in ECBSA design. The proposed antenna also exhibits the largest tuning range among the highpower mechanically-tuned cavity-backed slot antennas presented in the literature.INDEX TERMS Tunable slot antennas, evanescent-mode cavity, high-power, contactless tuning, substrateintegrated waveguide (SIW)
