Antenas de Microfita Linearmente Polarizadas: Nova Estratégia de Projeto

Nowadays, it is available in the literature the design procedure for probe-fed linearly polarized microstrip patch antennas. Following it, an antenna with inductive input impedance is obtained. In this paper, a new design approach is proposed to overcome this problem, even for antennas printed on thick substrates. This new approach is applied to rectangular and circular patches. Antenna with low-cost FR4 substrate at S-band is also treated. Very good results are obtained with this new design procedure, mainly for the impedance bandwidth.
