Abstract :
A frequency scanning antenna has been fabricated and tested at Ka-band using a layered ridge dielectric waveguide feed to an array of radiating strips. The antenna is easy to fabricate from low-cost microwave Teflon substrates. The radiation pattern for this antenna at 29 GHz is shown.<>
