We present design methodologies for directive millimeter-wave antennas using free-formed three-dimensional (3-D) electromagnetic bandgap (EBG) structures. Dispersion characteristics of 3-D EBGs have been computed by finite-difference time-domain (FDTD) simulations and the designed EBGs have been fabricated by using the extrusion free-forming technique. The fabricated EBG structures have been measured and integrated with a waveguide feed to form a Fabry-Perot cavity antenna. The prototype antenna demonstrated 10 to 14 beamwidths with measured gain of 13 dBi. The woodpile EBG antenna achieved a narrow beamwidth without resorting to complex arrays or bulky reflectors, which would make the antenna well-suited for millimeter-wave broadband mobile communications, imaging and space applications. Index Terms-Directive antenna, electromagnetic bandgap (EBG), metamaterial, millimeter-wave.

Electromagnetic bandgap structures (EBG) finds increasing number of applications in antennas and microwave devices. In this paper, we present an EBG resonator antenna based on woodpile structure at millimeter frequency. The dispersion characteristics of the woodpile structures have been analyzed using 3D FDTD codes with a periodic boundary condition (PBC). An annular slot antenna is used as the radiating element at 93GHz. For the construction of the woodpile structure, we use alumina rods (ε r = 9.6) with 0.4mm diameter. A new method is employed for the fabrication of the woodpile using extrusion freeforming technique. The freeforming technique is very useful to construct complicated 3D structures. The designed EBG antenna shows improved directivities. At 93GHz, directivity of 18dBi has been achieved, which is approximately 11dB improvement for the original antenna.

“…They are generally designed based on integrated circuits (ICs) [15][16][17], low-temperature cofired ceramic (LTCC) [18], micro-machined [7,19,20] or commonly used substrate technologies [5,8,11,14,[21][22][23]. The former two types infuse innovations into the mm-wave antenna technologies, but the latter are still the most popular ways so far for the majority of manufacturers and users due to their low investments on research and development.…”

Abstract-Although many directive antennas operating in a narrow band of millimeter (mm) waves were reported, e.g., antennas for 60-GHz wireless local area network (WLAN), their wideband counterparts are still unpopular. Cavity-backed antennas (CBAs) are widely developed and reported in microwave frequency bands, but handful of literatures can be found about mm-wave CBAs in spite that their many properties are quite suitable for mm-wave applications. This paper presents a wideband unidirectional CBA with a bowtie exciter, operating in a frequency band of 40 ∼ over 75 GHz, and it is carefully analyzed in terms of influences of all components on the radiation patterns, broadside gains, and reflection coefficients of the proposed antenna. Then, the antenna prototype is built by generic printed circuit board (PCB) technologies, and measurements prove the validity of simulations.
