	abstract = {A linearly polarized radial line patch antenna with internal coupling patches is presented. A non-resonant antenna structure has been designed, with a 0.68 ?0 radial spacing between element rings. A uniform amplitude and phase feed scheme has been implemented. Therefore, a phase compensation microstrip structure (external to the radial waveguide) has been included for a broadside radiation beam. Likewise, a compensation method has been used to avoid internal reflection problems in the waveguide. An antenna prototype has been built. 28.2 dBi gain and 70\% efficiency peak values have been measured at DBS band, with reasonable agreement between simulations and measurements.},

This coupling structure is based on microstrip lines placed inside the radial waveguide and connected to each radiating patch. By changing the dimensions of the microstrip lines, it is possible to achieve the desired feeding configuration. In order to check the validity of the new feeding mechanism, coupled field measurements are done in the radial waveguide. Likewise, a prototype antenna is manufactured in order to evaluate the behavior of the microstrip coupling lines when the radiating patches are connected to them.
