Air-bridge free coplanar waveguide power divider

A novel coplanar waveguide power divider implemented using bridgeless 90° bend coplanar waveguide to slotline transitions and exploiting the coplanar waveguide even and odd modes is proposed. The power divider operates at 5 GHz, has 1 dB insertion loss, and 3 GHz -3 dB insertion loss bandwidth. The theory of operation is developed. EM and circuit simulations are in good agreement. Experimental results confirm the theoretical predictions.
