BROADBAND PHASE ARRAY PATCH ANTENNA

摘要

PURPOSE: A patch antenna for a broadband phase array is provided to easily correct an antenna device by detecting an output signal through a signal detection port. CONSTITUTION: A substrate includes a first microstrip substrate(25) and a second microstrip substrate(26). A radiation patch(24) is installed on the surface of the first microstrip substrate. A feeding port(21) includes a feeding line and a capacitive patch(211) which is positioned on the first microstrip substrate and is capacitively coupled with the radiation patch. A signal detection port(22) includes a signal line and a capacitive patch(222) which is positioned on the second microstrip substrate and is capacitively coupled with radiation patch.
