Coplanar waveguide transition for multi-band impedance matching
First Claim
1. A microstrip antenna comprising:
- a first substrate;
a ground plane disposed on a first side of the first substrate;
a first conductive layer disposed on a second side of the first substrate, opposite the first side, wherein the first conductive layer is configured to resonate at a first frequency;
a second substrate disposed on the first conductive layer, opposite the first substrate;
a second conductive layer disposed on a side of the second substrate opposite the first conductive layer, wherein the second conductive layer is configured to resonate at a second frequency, the second frequency being different than the first frequency;
a first feed conductor extending through the first substrate and terminating at a first location of the first conductive layer, wherein the first feed conductor is configured to provide first excitation signals to the first conductive layer;
a second feed conductor extending through the second substrate and terminating at a second location of the first conductive layer that is offset from the first location, wherein the second feed conductor is configured to provide second excitation signals to the second conductive layer; and
a conductive strip disposed in the first conductive layer and extending from the first location to the second location and electrically connecting the first feed conductor and the second feed conductor.
