“…For example an integrated lens with an array of aperture coupled rectangular patches is feed by a microstrip feeding network at 28 GHz (Nguyen 2011) or at 60 GHz (Artemenko 2013a;Artemenko 2013b). …”

“…However, in this case the Nyquist criterion is not fulfilled. There are also some applications requiring multi-beam antennas but with a lower density of detectors like for a lens with an electrically reconfigurable beam shape (Nguyen 2011) or some degree of electrical controlled discrete beam steering (Costa 2008a;Artemenko 2013a;Artemenko 2013b).…”

Dielectric lens antennas are attracting a renewed interest for millimetre-and submillimetre wave applications where they become compact, especially for configurations with integrated feeds usually referred as integrated lens antennas. Lenses are very flexible and simple to design and fabricate, being a reliable alternative at these frequencies to reflector antennas. Lens target output can range from a simple collimated beam (increasing the feed directivity) to more complex multi-objective specifications.This chapter presents a review of different types of dielectric lens antennas and lens design methods. Representative lens antenna design examples are described in detail, with emphasis on homogeneous integrated lenses. A review of the different lens analysis methods is performed, followed by the discuss ion of relevant lens antenna implementation issues like feeding options, dielectric material characteristics, fabrication methods and a few dedicated measurement techniques. The chapter ends with a detailed presentation of some recent application examples involving dielectric lens antennas.

“…However, as a rule, one should implement a mechanical system to provide a continuous beam steering capability [9]. Another way is to use several feed antennas to provide discrete switching of the beam position [10]. Both approaches lead to an increase in the system's complexity as well as cost.…”

“…The principles of lens antenna design are the origins of designing so-called "quasi-optical" beamforming devices (QOBD) in micro-and millimeter-wave bands. There are a lot of different QOBD constructions with various beamforming functions such as focus lenses [10], deflectors [11], polarization controllers [12], etc. The realization of tunable QOBD beamforming functions relies on the use of nonlinear elements such as PIN diodes [13], semiconductor or ferroelectric (FE) varactors [14], and microelectromechanical systems (MEMS) [15].…”

agaltynnikov@etu.ru (A.A.); abkozyrev@etu.ru (A.K.) * Correspondence: raplatonov@etu.ru; Tel.: +7-812-234-4809 † These authors contributed equally to this work. Abstract:The advanced design of a millimeter-wave quasi-optical beamforming device (QOBD) based on the ferroelectric ceramic was elaborated and considered. Among the advantages of the proposed design are simplicity and cost-effectiveness in contrast to conventional analog and digital beamforming devices based on array antennas. The use of ferroelectric ceramic in the QOBD design allows operating in a wide frequency range up to 100 GHz. The advanced topology of discrete radiotransparent electrodes to provide a realization of different beamforming functions such as beam focusing and beam scanning was considered. The prototype of the proposed QOBD was designed to operate at 60 GHz. The measured radiation pattern of the QOBD prototype is in good agreement with the simulated one. Measurements demonstrate decreasing of beamwidth of the primary antenna radiation pattern by the lens prototype operating in the beam focusing regime.

International audienceAn antenna array operating at 60 GHz is proposed. The proposed array covers impedance bandwidth of 5 GHz (57.5–62.5 GHz) with maximum gain of 16.25 dBi at 61. 5 GHz. With the proposed array 15 distinct radiation patterns in azimuth plane can be achieved, each having 3-dB beamwidth of 24° and 3-dB cross over. The beam scanning capability can be achieved by activating each array element one by one. Each array element consists of a conventional microstrip patch antenna (MPA) integrated with extended hemispherical Teflon lens. The Teflon lens is utilized to enhance the gain of conventional MPA as well as to achieve the desired elementary radiation pattern of array to cover full azimuth plane. A very good agreement between the measured and simulated results is observed. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:116–120, 2017. © 2016 Wiley Periodicals, Inc
