“…There are a number of methods proposed to tailor the properties of EBG cells such as interdigitation [6,16,17], trimming [9], and much less commonly, thickening [5,18,19]. In this section, these methods are applied to the thin via-less mushroom-like EBG cell in Fig.…”

“…Maintaining the radiation efficiency (originating from the ohmic loss) of a small antenna is also a challenge in antenna miniaturization. Consequently, considerable effort has been dedicated to the design of efficient and compact passive RF components [1][2][3][4][5][6][7][8][9][10]. A number of size reduction methods have been studied, including using fractal-shaped patterns [10], applying dielectric [2] or magnetic [11] materials around the element, utilizing lumped [2] or parasitic [1] elements, applying metamaterial based ideas [9], enhancing the slow-wave behavior through periodic loading [12], etc..…”

“…The electromagnetic bandgap (EBG) concept [3][4][5][6][7] has also demonstrated remarkable potential for size reduction and various other advantages such as bandwidth and gain enhancement, surface wave suppression, and loss mitigation. More specifically, it has been repeatedly shown that incorporating EBG cells into RF structures can reduce their resonance frequency (f r ) [6][7]13].…”

“…Miniaturization techniques to reduce the resonance frequency of the basic unit cell using a Bloch-based cell modeling approach are presented. Improved, compact EBG cells are applied to the structure of a new-type of antenna called self-excited EBG resonator antenna (SE-EBG-RA), first presented in [5]. The original SE-EBG-RA with the basic EBG cell [5] is compared to the new version developed here with improved cells.…”

Abstract-The paper presents a methodology to achieve efficient low-profile electromagnetic bandgap (EBG) antennas based on thick EBG unit cells. The EBG cells are composed of thick metal patches separated by narrow high aspect ratio (HAR) gaps, and positioned on a PEC-backed substrate. This approach yields new miniaturized EBG cells with considerably reduced electrical size. The miniaturized cells are employed to demonstrate new compact self-excited EBG resonator antennas with considerably reduced operating frequencies. Full-wave simulations and experimental results demonstrate the design approach.

A compact patch antenna periodically loaded by air gaps is presented. The gaps are arranged to create EBG cells, which affect the dispersive behaviours of the patch (as a transmission line). This causes waves to travel faster along the patch, and increases the cumulative radiation from the structure. The proposed antenna is compared with its conventional counterpart, considering the efficiency, electrical/physical size and the potential to achieve an electrically small footprint. Experimental results validate the analyses.

Aabstract -An efficient planar array antenna composed of thick electromagnetic bandgap (EBG) antenna elements is proposed. The element, called SE-EBG-RA, is an efficient EBG antenna introduced in literature. The array comprises equallyspaced series-fed elements designed to have broadside radiation. A computationally efficient approach is presented to form the array in series with negligible mutual coupling between elements. To this end, first the terminated version of SE-EBG-RA element is introduced. Then, it is shown that how such elements can structure the series array effectively. Results show that the application of EBG cells and thick traces yields high efficiency, alleviated mutual coupling, and a symmetrical broadside pattern with reduced numerical computation load.
