Abstract-The patch antennas with an array of pins (pin array p atch antennas) with excellent radiation characteristics are investigated for var ious substrate thicknesses. The radiation in the horizontal plane of a pin array patch antenna is very small compared to that of a conventional patch antenna. A nd the increase of forward radiation and the decrease of backward radiation of a pin array patch antenna are obtained than those conventional one′s. Also the h alf-power beamwidth of E-plane radiation pattern of a pin array patch ante nna is narrower compared to that of the conventional so that the directivity is improved.
Key words-microstrip patch antennas pin arrays; radiati on characteristics; substrate thickness
