In this paper, a method for simultaneously realizing the sum and difference patterns which are required in the monopulse radar sensor systems, is presented by using single taper array antenna with rectangular microstrip patches. The widths of patches are first determined by the voltage weights which are synthesized for the fundamental array factor patterns to be applied to the monopulse operation by using the sidelobe levels(SLLs) control technique. As the bi-directionally series-fed technique is applied and the lengths of connecting lines between patches are appropriately adjusted, the single array generates two phase-shifted beams which activates out-of-phase and in-phase ports of a 180° hybrid coupler to synthesize the sum and difference patterns. The simulated results on the configuration designed at 9.5 GHz are compared with measured results showing the validity of the proposed method.

“…This frequency is convenient in that it is a harmonic of existing beamlines (" 32 × SLAC "), making possible certain tests with beam. Moreover, research in W-Band benefits from years of development for applications throughout society (11), as well as recent scrutiny for accelerator applications (12)(13)(14). By our choice of frequency, we do not mean to suggest that higher frequencies are somehow less interesting.…”

We recall the motivation for research in high-gradient acceleration and the problems posed by a compact collider. We summarize the phenomena known to appear in operation of a solid-state structure with large fields, and research relevant to the question of the ultimate gradient. We take note of new concepts, and examine one in detail, a miniature particle accelerator based on an active millimeter-wave circuit and parallel particle beams.

“…The rapid expansion of wireless communications and personal communication networks has led to tremendous demands of miniaturization, portability, low-manufacturing cost and high performance in RF and millimeter-wave (mmW) wireless systems [2]. Especially, the appeal for transmitting multimedia information using high-speed digital data and wideband image signals has motivated the development of 60 GHz wireless communication systems because of their high potential for achieving compactness and wide bandwidth [3].…”

-In this paper, a new class of compact cavity-based three dimensional (3D) filters and enhanced-performance antennas is proposed for 60 GHz miniaturized front-ends for multilayer low-temperature co-fired ceramic (LTCC) V-band modules. The low-loss cavity resonator consisting of via fences as sidewalls has been designed to be used as a filter. The probe excitation is employed for the feeding structure and is demonstrated as an attractive option for wideband applications due to its relatively wide bandwidth performance (1.8%) compared to the slot excitation with a g /4 [1]. Its low loss performance is verified through an insertion loss lower than 0.95 dB over the 3-dB pass band. Plus, an aperture-coupled patch antenna integrated with a soft surface and an underlying stacked cavity below the antenna substrate has been demonstrated on a novel LTCC composite multilayer technology with variable layer dielectric constant as a potential enhanced-performance antenna topology with a higher gain (~7.6 dBi) and a significantly lower backside radiation (at least 5.1 dB) as compared to the use of soft surface only. The proposed compact antenna topology is easily extendable to array configuration for point-to-point applications in short-range indoor wireless personal area networks (WPAN) Index Terms -cavity resonators, low-temperature cofired ceramic (LTCC), V-band, three dimensional (3D) integration, probe excitation, patch antenna, soft surface, composite substrate, mm-wave, WPAN.
