Recently, several designs of single fed circularly polarized microstrip antennas have been studied. Relatively, a few designs for achieving circular polarization using triangular microstrip antenna are available. Typically existing design of single fed circularly polarized triangular microstrip antennas include the use of equilateral triangular patch with a slit or a horizontal slot on the patc...

This paper demonstrates a power supply noise reduction using on-board stubs. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply noise of the designed frequency. Preliminary experiments show that 87% of the designed frequency noise component is suppressed when stub patterns are written on a power supply area on...

This paper compares a stub and a decoupling capacitor for power supply noise reduction. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply bounce of the designed frequency. The conditions where the stub is more effective than the same-area decoupling capacitor are clarified. The stub will work more efficiently...

base types in any byte order. USC requires stub parameters that give the lengths of any variable length array arguments. The code below copies one variable length character array to another. len gives the current length of the arrays. void foo (len, str1, str2) int len; /* Must be a native type */ char str1[len]; /* May be native or not */ char str2(1, 4, 4, <0>)[len];/* May be native or not */...

We report recent results on a 580-740 GHz SIS heterodyne receiver employing a tuned 0.50μm Nb/AlOx/Nb SIS tunnel junction. The receiver has been successfully installed at the Caltech Submillimeter Observatory, Hawaii. Results of an untuned device in the same waveguide block were presented at the fifth International THz Conference. Since the mixer is meant to be operated near the supercodunting ...

A novel circular micro strip dual band stub loaded antenna is described. The antenna is built with a dielectric constant of (?r =2. 33) with RT/5870 as the substrate material. Due to the effect of stub loading, dual frequency is produced at 1. 88 GHz and 2. 73 GHz respectively for the stub length=17 m. m. With the further increment of stub length, shifting of secondary resonant frequency is pos...
