An essential performance metric for a high-power microwave (HPW) array antenna's power handling capability is mainly determined by the magnitude of the electric field at the slots of the array. The power handling capability of an L-Band waveguide longitudinal shunt slot array with different slot widths is determined through simulation and measurement. Analysis shows that there is an optimum slot width resulting in maximum power handling capability. Different slot shapes are examined, including rectangular, end-rounded rectangular and elliptical. The results indicate that a longitudinal shunt elliptical slot array provides the highest power handling capability. [ABSTRACT FROM AUTHOR]

A compact dual-band linearly and circularly polarized monopole antenna employs an inverted L-shape and an asymmetric ground plane fed by a coplanar waveguide (CPW). The inverted L-shape strip produces an orthogonal component in the ground plane and monopole distinct from its original linear polarization (LP). By embedding a slit on the ground plane, this antenna achieves a broad impedance bandwidth and circular polarization (CP). Measurements demonstrate a 10 dB bandwidth of 92.7 percent from 3.3 to 9 GHz and a 3 dB axial ratio (AR) bandwidth of 57.1 percent from 5 to 9 GHz, capable of covering the 5.725 to 5.85 GHz WLAN band. Meanwhile, LP is also obtained covering the 3.3 to 3.7 GHz WiMAX band. Compared with other recent work, wider axial ratio and impedance bandwidth, as well as a simpler, more compact structure are the key features. [ABSTRACT FROM AUTHOR]

A transmission line employing a periodic structure was fabricated on a polyether sulfone (FES) substrate and its RF characteristics were investigated. A fishbone-type transmission line, employing a comb-type ground plane (FTLCGP) structure, was designed to reduce the wavelength. The FTLCGP structure on PES substrate showed a wavelength much shorter than for a conventional coplanar waveguide on PES. The FTLCGP structure on the PES substrate showed an attenuation constant a lower than 0.2 Np/mm, up to 40 GHz, which was much lower than for a transmission line on a commercial silicon substrate. Using the FTLCGP structure, a miniaturized impedance transformer was fabricated on a PES substrate for flexible RFIC ¦ applications. The size of the impedance transformer was 0.45 mm2, which was 57.5 percent of the size of the transformer fabricated by conventional coplanar waveguide on PES substrate. The return and insertion losses were 43 and 0.74 dB, respectively, at a center frequency of 22 GHz and the return loss values were better than 10 dB and the insertion loss was better than 1.1 dB up to 46.4 GHz.
