Using L-probe patch antennas as elements, a simple series-fed eight-element
array antenna is designed and tested. An impedance bandwidth of 8% (SWR le
ss than or equal to 1.5) and an average gain of 14.5 dBi have been achieved
. The radiation pattern is stable across the passband with low cross polari
zation. (C) 2001 John Wiley & Sons, Inc.
