A multi-frequency patch antenna with double-sided parallel-strip line (DSPSL) periodic offset structure is proposed. The designed antenna consists of a simple rectangular patch as well as an embedded one-dimensional DSPSL periodic offset structure, which is employed to replace the traditional rectangular microstrip patch antenna. The periodic DSPSL structure is characterized leaky wave structure. After the periodic DSPSL structure is embedded, the resonance frequency of rectangular patch is offset, and the leaky wave characteristics can determine the number and position of new operating frequencies. As an application, a tri-band antenna is manufactured and these three operating frequencies can be calculated by the derived formulas studied in this communication. Experiment results suggest that the antenna can work at 4.28, 4.78, and 6.42 GHz, respectively. The results of simulated, measured and calculated show high consistency.

“…Transmission line sections with the required values (ZB=70.71 and lTL/2vp= 9.59 ps) are added at both sides of the X-type left handed unit cell to provide the needed phase shift. This transmission line sections are implemented by means of double sided parallel strip line (DSPSL) [34] with an offset equal to 0.66 mm (this gives the required impedance) and connected to the X-type left handed lattice network with tapered line sections, that have been optimized to achieve the required phase response (the tapper lines are necessary to connect the lines to the X-type network, which has the indicated shape in order to accommodate the inductive vias, and to provide the required capacitive values). As expected, the required phase shift at the operating frequencies is achieved.…”

This paper proposes a dual-band power divider operating at GHz frequencies and implemented by means of impedance transformers (also called inverters) based on lattice networks and transmission line sections. The dual-band functionality of the proposed device is achieved thanks to the composite right/left handed (CRLH) behavior of the impedance transformers, able to provide 90 o and +90 o phase shift at the first and second design frequencies, respectively, of the divider. By using such combination of transmission line sections and lattice networks, the characteristic impedance of the impedance transformers is roughly constant over wide bandwidths, with the results of broad operating bands. To demonstrate the possibilities of the approach, a prototype device is designed, fabricated and characterized.

This study presents a novel dual‐band DC biasing network and its application in the design of GaN power amplifiers (PAs). By integrating offset double‐sided parallel strip line which can easily realise high characteristic impedance and thus narrow microstrip line, the proposed biasing network can obtain much higher operation frequency ratio than the conventional design. To demonstrate the new methodology, two dual‐band GaN PAs applying the presented dual‐band DC biasing network are implemented. The operation frequencies are 1.8/3.5 and 0.9/3.5 GHz. Three‐section networks for complex load are used for dual‐frequency input and output matching. Good agreement between the simulation and measurement is observed, which fully demonstrate the feasibility and validity of the presented DC bias networks in power amplifier designs.
