摘要：

The design of electrically steerable traveling wave microstrip, antenna arrays is presented. Varactor diode based phase shifters implemented on the same metallic layer as the patch elements are used to provide a variable progressive phase shift in the array. Two antennas for the 5.8 GHz ISM band, manufactured as single layer printed designs on a standard PTFE soft substrate, are demonstrated. A ten-element beam-tilting vertical array using transmission type phase shifters is realized, yielding between 11.8 to 13.9 dBi gain for the 0 degrees to 11 degrees beam tilt tuning range. Using wide phase tuning range reflection type phase shifters; a five-element horizontally scanning array with -32 degrees to 32 degrees steering range and 10.9-11.3 dBi gain has been realized.
