✦ Synopsis
A new acti¨e coplanar wa¨eguide CPW to coplanar ( ) strips CPS -fed microstrip leaky-wa¨e antenna is de¨eloped, which is integrated with a Gunn diode as an acti¨e source. The CPW᎐CPS balun is used to excite the first higher order mode of the microstrip leaky-wa¨e antenna. The acti¨e leaky-wa¨e antenna has a maximum EIRP of 20.4 dBm at 9.759 GHz. The Gunn oscillator frequency is controlled by tuning the Gunn dc bias, and the beam scanning is demonstrated. The measured scanning angle agrees with the prediction; it is close to 12Њ as the oscillator frequency is tuned from 9.84 to 9.61 GHz. The coplanar structure allows easy integration of many solid-state de¨ices. It is suitable for monolithic power combining and millimeter-wa¨e applications.
