The proposed array designs for 15, 28, and 60 GHz are printed on a same Rogers (RO3003) substrate with relative permittivity [[epsilon].sub.r] = 3, loss tangent 0.0013, and thickness 0.13 mm.

Under the condition of cross-polarization reflection coefficient great than -1dB, the operating band of the PCM is from 10.45 GHz to 32.15 GHz (relative bandwidth of 101.9%).

To accomplish mobility across the company, City Furniture wanted to upgrade from its existing Cisco 802.11g network to a high throughput, 5 GHz-capable solution which allows all showroom iPads and corporate laptops at City to utilize the 5 GHz frequency with minimal channel congestion and better throughput.

* Additional topics were raised for global flight tracking (1087-71092.3 MHz frequencies identified) and road safety (77-81 GHz frequencies identified for short-range high-resolution automotive radar).

Generally speaking, the rectangular micro-strips can generate transmission zero around 13 GHz. T and L slot-lines can create transmission zeros at about 18 GHz and 25 GHz.

The measured impedance bandwidths for [S.sub.11] [less than or equal to] -10 dB are about 250 MHz (2.40-2.65 GHz) resonated at 2.50 GHz, 705 MHz (3.3-4.05 GHz) resonated at 3.6 GHz, and 980 MHz (5.00-5.98 GHz) resonated at 5.1GHz, which can fulfill both the WLAN bands (2.4-2.485 GHz, 5.15-5.35 GHz, and 5.7255.825 GHz) and the WiMAX bands (2.5-2.69 GHz, 3.4-3.69 GHz, and 5.25-5.85 GHz).

A Network Analyzer (6 GHz ZVL of Rohde & Schwarz) has been used to measure the propagation loss at the (2.4, 3.3 and 5.5) GHz bands.

The 21.5-inch iMac is available with a 2.7 GHz quad-core Intel Core i5 with Turbo Boost speeds up to 3.2 GHz and NVIDIA GeForce GT 640M for a suggested retail price of Rs.

The Anritsu MS2830A Signal Analyzer, when coupled with the OML MxxHWD harmonic mixer, offers mm-wave frequency coverage from 26.5 GHz to 325 GHz.

The high-end of the two, the xw8400, unlike the xw6400, can support up to two Xeon 5000 processor (from 3.0 GHz to 3.73 GHz, 2-MB on-chip [L2] cache per processor core) or up to two Xeon 5100 processors (from 1.60 GHz to 3.00 GHz, 4 MB shared L2 cache per processor).

The three models include a 1.83 GHz and 2.0 GHz notebook in a white enclosure and a 2.0 GHz notebook in a black enclosure.
