Abstract
A miniature variable-beam microwave antenna () comprises antenna conductors (), an EBG conductor (), a variable reactance element (), and an adjusting part (). The EBG conductor () is connected to a grounded part () through the variable reactance element (). The adjusting part () changes the apparent reactance of the EBG conductor () by changing the capacity of the variable reactance element (). As the apparent reactance of the EBG conductor () changes, the directivity of the miniature variable-beam microwave antenna () also changes.
