“…The performance of the proposed EBG is compared with earlier reported unit cells in Table 1. Compared to unit cells in [4,[6][7][8][9][10][11], the proposed geometry achieves a higher bandgap with comparable unit-cell periodicity and thickness. Moreover relative to mushroom-type EBGs in [4,[6][7][8], the proposed uniplanar configuration has an added advantage of less fabrication complexity due to the absence of metallic via.…”

“…EBG is broadly classified as mushroom [2] and uniplanar type [3], which exhibits properties such as surface wave suppression within its frequency bandgap and in-phase reflection for plane wave incidence. EBG is integrated with a planar array for mutual coupling reduction [4] and low profile compact antenna design [5]. In recent years, different miniaturized mushroom [6][7][8] and uniplanar EBG [9][10][11] geometries are reported and their applications are presented in detail.…”

This paper presents a broadband miniaturized Fabry–Perot cavity resonator antenna (CRA) made of novel electromagnetic bandgap (EBG) superstrate as partially reflecting surface (PRS) and reactive impedance surface (RIS) backed rectangular patch antenna. To the best of the authors' knowledge, the proposed EBG exhibits the highest stopband bandwidth (BW) with a bandgap existing between 7.37 and 12.4 GHz (50.9%). Frequency-selective property of the EBG is utilized under plane wave incidence to demonstrate it as PRS superstrate in CRA antenna. The cavity is excited with a rectangular microstrip antenna which is made of two dielectric substrates with an additional RIS layer sandwiched between them. The RIS provides wideband impedance matching of the primary feed antenna. A 7 × 7 array of the EBG superstrate is loaded over the patch antenna having an overall lateral dimension of only 45 × 45 mm2 or 1.62 λ0 × 1.62 λ0 where λ0 is the free space wavelength at the center frequency of 10.8 GHz. The proposed Fabry–Perot CRA (FP-CRA) achieves gain enhancement of 6.59 dB as compared with the reference antenna and has a 10 dB return loss BW of 23.79% from 10.07 to 12.79 GHz. A prototype of the FP-CRA is fabricated and experimentally tested with single and dual layers of EBG superstrate. Measured results show BWs of 21.5 and 24.8% for the two cases with peak realized gain of 12.05 and 14.3 dBi, respectively. Later a four-element antenna array with corporate feeding is designed as the primary feed of the CRA. The simulation result shows a flat gain of >13 dBi with gain variation <1.2 dB over the impedance BW of 13.2%.

This paper presents the design of antenna for Internet of Things (IoT) applications. The performance of conventional antenna is limited by surface waves due to which it produces a low gain. An attempt is made to reduce the surface wave excitations in conventional antennas with the use of integration of Electromagnetic Band Gap (EBG) cells. The proposed work involves the design of Edge via EBG unit cell at 5.2 GHz and it is simulated with High Frequency Structure Simulator (HFSS) software. The simulation results show that the gain is enhanced by 10% and S11 is reduced by 72%, approximately in the rectangular microstrip patch antenna with Edge via EBGs.

A design method of metal coaxial resonator antenna (MCRA) is proposed in this article. According to this method, a broadband MCRA working in highorder modes is designed. The proposed antenna fuses two frequency bands of different high-order mode pairs, thus achieving 30% fractional bandwidth. The measured operating frequency band of the antenna is 2.95-4.1 GHz, in which the gain is more than 8.5 dBi. In addition, in order to improve the gain, a lowprofile dielectric lens (DL) is designed. With the DL loaded, the À10 dB S11 band shifts to 3.1-4.1 GHz, and the gain of is more than 11 dBi. A close agreement has been achieved between the measured and simulated results.
