This paper presents the design of a V-band switched-line phase shifter using SP4T RF-MEMS switches. Sonnet simulations are used to achieve accurate circuit models of both the RF-MEMS switches as well as CPW bends within the phase shifter. The V-band phase shifter utilizes two SP4T RF-MEMS switches to perform the delay line switching. The RF performance of the SP4T MEMS switch is optimized to ad...

Abstract- Design and simulation of a very small size 6-bit DMTL phase shifter is presented. The idea is based on using both capacitor and resonator type methods simultaneously in a phase shifter. The capacitor section creates less significant bits. The bits in this section start from the least significant bit, with 5.625-degree steps. The resonator section creates the bits with 90-degree steps....

A configuration for a miniaturized band-pass filter on a coplanar waveguide (CPW) is proposed in this communication. Parametric studies conducted for various geometrical parameters suggest that the frequency response of the filter is strongly related to that of the spiral slots. A a series gap on the center conductor of the CPW changes the overall response of the device. For validation of these...

This paper presents a simple broadband proximitycoupled microstrip patch antenna. A circular patch is used as the main radiator, and an H-shaped shot is cut in the ground plane below the feed line. A stepped-width microstrip line is used to feed the patch through proximity coupling. By using a single patch, the prototype antenna achieves an impedance bandwidth of 26%. Low cross-polar levels bel...

The study of Microstrip patch antennas have made great progress in recent years. Compared with conventional antennas, Microstrip patch antennas have more advantages and better prospects.

Moreover, the Microstrip patch antennas can provide dual and circular polarizations, d...

A novel ultra-wideband (UWB) monopole antenna with triple band-notched functions is presented. A pair of folded multiplemode resonators (MMR) symmetrically coupled to the feed line are utilized to generate triple notched bands for WiMAX, WLAN and downlinks of X-band satellite communication, respectively. The centre frequencies and band gaps between them can be tuned by varying the length and wi...
