Abstract
A wireless communication device can include a channel matching network. The channel matching network includes a pair of coupled lines coupled to the input port, and a capacitive element coupled between the pair of coupled lines and an antenna load.
Claims15
A channel matching network comprising:
- an antenna having an input port and a pair of coupled transmission lines coupled to the input port;
- a grounded capacitive element coupled between one of the pair of coupled transmission lines and an antenna load;
- and
- an asymmetrical attenuator coupled between the grounded capacitive element and the antenna load.

A method for communicating in a mm Wave network, the method comprising:
- providing a transmit antenna to communicate over a channel;
- providing a pair of coupled transmission lines at the transmit antenna;
- providing a grounded capacitive element between one of the pair of coupled transmission lines and an antenna load of the transmit antenna;
- setting a characteristic impedance and length of the pair of coupled transmission lines based on a frequency band of operation of the channel;
- transmitting a signal from the transmit antenna on the frequency band;
- providing an attenuator coupled between the grounded capacitive element and the antenna load of the transmit antenna;
- and
- setting attenuation values of first attenuator based on at least one of a reflection coefficient (S11) of the transmit antenna, and a forward transmission (S21) of the transmit antenna.
