“…The measured radiation patterns at 9. 5 Figure 7 illustrates that the gains of the 16 ϫ 16 X-band array is 30 Ϯ 0.4 dB from 9.4 to 10.7 GHz frequency range for both polarizations, which implies an aperture efficiency of about 55%. It is slightly lower for horizontal polarization than that of the vertical one, probably due to the lower slot coupling excitation efficiency.…”

“…We investigate electromagnetic plane-wave excitation with different polarizations incident on a homogeneous rectangular box phantom (corresponds to the average trunk of an adult man, CENELEC [3]), a homogeneous prolate spheroid phantom (average man [4], widely used simplified model of a human), and a realistic heterogeneous model of a man (Visible Human, developed at Brooks Air Force Base Laboratories [5]). Plane-wave excitation is a worstcase situation, necessary for the evaluation of safety compliance [2,3].…”

A 30-GHz amplifier has been successfully designed and measured using TSMC standard 0.18-m CMOS process. Through accurate device model and full-wave EM simulation including transmission lines, MIM capacitors, and pads, the frequency response of LNA can be precisely expected. To the author's best knowledge, this LNA achieved the best performances among the previous works concerning in operating frequency, gain, IP 1 dB , IP3, and noise figure. This work proves the standard CMOS process has great potential for millimeter-wave applications. A 24-GHz 3.9-dB NF low-noise amplifier using 0.18-m CMOS technology, IEEE Microwave Wireless Compon Lett 15 (2005), 448 -450. 2. X. Guan and A. Hajimiri, A 24-GHz CMOS front end, IEEE J Solid-ABSTRACT: The design and development of a broadband dual-polarized 16 ϫ 16 element microstrip antenna array for X-band application is introduced. The measured bandwidth is about 17.8% for voltage standing wave ratios Ͻ1.5. The polarization isolation is better than 45 dB. The cross-polarization component is at the level of Ϫ37 dB below the main lobe.ABSTRACT: A correction factor dependent upon frequency, type of phantom, and incident polarization, which should be applied to the mea-sured specific absorption rate is proposed for homogeneous phantoms. It is shown for an application of occupational exposure in the neighborhood of a base station antenna that this correction factor not underestimates realistic exposure of workers.

“…In [4] a design strategy can be found allowing to achieve bandwidth in excess of 25°k. Different techniques can be found in literature which allow for achieving high isolation between ports generating orthogonal polarization in either aperture coupled or probe-fed patches [5], [6], [7]. In [5] and [6] two H-shaped slots placed orthogonally in a 'T' configuration are used for improving isolation between ports exciting vertical and horizontal polarizations.…”

An integrated dual-band dual-polarized antenna element for SAR applications is presented. The antenna operates in Land C bands in which 8%and 7% bandwidths are achieved respectively. In order to ensure wide bandwidth of the radiating elements stacked patches in both frequency ranges are used. The L-band radiating elements (both driven and parasitic patches) have been perforated in such a way that can be integrated with four C-band elements. In order to achieve high isolation between ports exciting orthogonal polarization dual-probe technique has been applied in L-band and orthogonal placement of two coupling slots has been applied in C-band. To allow for further integration within a larger array the feeding network has been designed in multilayer stripline structure. The measured results of the manufactured antenna element are in good agreement with the calculated ones.

“…These antennas require high isolation and low cross-polarization. Due to the poor isolation between the two ports (about 20dB) of conventional rectangular patches excited along two orthogonal edges, a few multilayer microstrip antennas have been studied: slot-coupled stacked patch antenna [1] and a multilayer feeding network structure [2]. However these structures are too complex.…”
