Abstract

A planar array composed of 41 parasitic dipoles, above a ground plane, fed by an active dipole at 5 GHz, was designed to obtain a pencil beam pattern with a moderate gain and bandwidth. Experimental results are in good agreement with the theory and show a pattern with an 18.78 dB gain, a sidelobe level (SLL) of -15 dB, an impedance bandwidth of 16.53% (the frequency range over which the value of S11 is below -10 dB) and a 2.7% bandwidth that is achieved within 1 dB gain variations.
