@article {15_RadialLineIEEE, title = {Linearly Polarized Radial Line Patch Antenna With Internal Rectangular Coupling Patches}, journal = {IEEE Transactions on Antennas and Propagation}, volume = {59}, number = {8}, year = {2011}, month = {Aug.}, pages = {3049 - 3052}, 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.}, keywords = {Internal rectangular coupling patch, microstrip phase compensation line, radial line patch antenna (RLPA)}, issn = {0018-926X}, doi = {10.1109/TAP.2011.2158945}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=5784312}, author = {J L Masa-Campos and Sierra-P{\'e}rez, M} }
