Patent ID: 10581166

Abstract:
There is disclosed a multi-band reconfigurable antenna device having at least one radiating element. The radiating element is connected to a single port by way of at least first and second matching circuits arranged in parallel. A high pass filter is provided between the first matching circuit and the radiating element so as to allow passage of a first, higher frequency RF signal through the first matching circuit. A low pass filter is provided between the second matching circuit and the at least one radiating element so as to allow passage of a second, lower frequency RF signal through the second matching circuit. The high pass filter blocks passage of the second, lower frequency RF signal through the first matching circuit, and the low pass filter blocks passage of the first, higher frequency RF signal through the second matching circuit. The first and second matching circuits are adjustable independently of each other so as to allow the first and second RF signals to be tuned independently of each other.
