With the increasing demand for different applications of antennas, especially multi-band and ultra-wideband antenna, we propose a novel tri-band, ultra-wideband (UWB) antenna with deformed split ring resonator (DSRR). The antenna consists of a partly covered ground plane and a deformed split ring resonator. By integrating the partly covered ground plane and the deformed split ring resonator and optimizing with CST Microwave Studio numerically, the proposed antenna produces three working bands ranging from 2.87GHz to 3.92GHz, 5.08 to 6.30GHz and 7.55 to 9.32GHz, which also satisfy the requirement of UWB. The three working bands cover the WIMAX band in 3.5GHz, the WLAN bands in 5.2/5.8GHz, and X-band, respectively. The radiation pattern is omnidirectional and the direction gain at every frequency is above 3.2 dBi. So the proposed antenna is suitable for multi-band communication applications.

This work presents the design and evaluation of a planar device for microwave heating of liquids in continuous microfluidics (CMF) made in polydimethylsiloxane (PDMS). It deals with volumes in the µL range, which are of high interest and relevance to biologists and chemists. The planar heater in this work is conceived around a complementary split-ring resonator (CSRR) topology that offers a desired electric field direction to—and interaction with—liquids in a microwell. The designed device on a 0.25 mm thick Rogers RO4350B substrate operates at around 2.5 GHz, while a CMF channel and a 2.45 µL microwell are manufactured in PDMS using the casting process. The evaluation of the performance of the designed heater is conducted using a fluorescent dye, Rhodamine B, dissolved in deionized water. Heating measurements are carried out using 1 W of power and the designed device achieves a temperature of 47 °C on a sample volume of 2.45 µL after 20 s of heating. Based on the achieved results, the CSRR topology has a large potential in microwave heating, in addition to the already demonstrated potential in microwave dielectric sensing, all proving the multifunctionality and reusability of single planar microwave-microfluidic devices.
