Abstract :
A printed L-probe antenna fabricated on a multi-layered printed-circuit-board (PCB) with a very wide operating band is proposed. This antenna is a four-layered structure, consisting of a circuitry layer, ground layer, probe layer, and patch layer. The printed part of the L-probe provides extra degrees of freedom for tuning the antenna, achieving a wide operating frequency. A printed L-probe antenna centered at the frequency of 6.5 GHz was designed with a measured impedance bandwidth of 40% with constant radiation patterns across the operating band.
