“…Microstrip array antennas fed by microstrip lines were developed for automotive radars [23], [24], where a simple feed structure was introduced by placing the feed line and the radiating elements in the same substrate. A multilayer parasitic microstrip antenna array was discussed on polytetrafluoroethylene (PTFE) substrate [25], where the multilayer parasitic structure would increase the antenna size without feed lines.…”

SUMMARY Array antenna technology for wireless systems is highly integrated for demands such as multi-functionality and high-performance. This paper details recent technologies in Japan in design techniques based on computational electromagnetics, antenna hardware techniques in the millimeter-wave band, array signal processing to add adaptive functions, and measurement methods to support design techniques, for array antennas for future wireless systems. Prospects of these four technologies are also described. key words: array antenna, multiple antenna, computational electromagnetics, millimeter-wave, antenna measurement, signal processing

“…DBF systems need vertically-long sub-arrays arranged in horizontal plane. As the antenna gain of the sub-array is relatively low, both microstrip [8] and waveguide antennas [9], [10] are possible as shown in Figs. 1 (a) and (b), respectively.…”

Two types of millimeter-wave planar array antennas for electronic beam-scanning systems are developed in this work. Several vertically-long sub-arrays are arranged horizontally for beam forming in array signal processing of horizontal plane. On the other hand, the vertically-long subarrays are developed in travelling-wave design. The travellingwave feeding system is advantageous for simple configuration and low-loss operation in millimeter-wave band. Waveguide antennas and microstrip antennas are developed for sub-arrays of electronic beam-scanning systems. Features and advantages of microstrip antennas and waveguide antennas designed for beamscanning systems are discussed in this paper.

“…This antenna is composed of a waveguide-to-microstrip mode transition which is for direct feeding from a waveguide, equi-spaced radiation elements on both sides of a microstrip line and a terminated element. This type of antenna was proposed previously [3]- [4] due to low-cost configuration and mass productivity, but the bandwidth was narrow, if thin film substrate is used. The symmetrical side-coupled parasitic elements on both sides of each radiation element and an end-coupled parasitic element at edge of the element are set for bandwidth enhancement.…”

In this paper, a microstrip comb-line array antenna with parasitic elements for bandwidth enhancement at 60 GHz band is proposed. The antenna is fabricated on liquid crystal polymer (LCP) substrate due to its low dielectric loss. The antenna consists of a waveguide-to-microstrip mode transition, 16 radiation elements which construct an one-dimensional array and a terminated element. Two side-coupled parasitic elements are set symmetrically on both sides of each radiation element and an end-coupled parasitic element is set at the edge of the element for the sake of bandwidth enhancement. The antenna can be made consistently for the emerging market in the near future. Good agreement between simulated and measured results is obtained. Around 5% impedance bandwidth for |S 11 | less than -10 dB and 10% gain bandwidth for maximum gain over 10 dBi are finally obtained.
