چکیده
|
A compact broadband sequential feeding network designed for a wideband circular antenna is simulated and fabricated, where the 50-ω input is equally divided into four 50-ω outputs with equal amplitude and 90° successive shifts. this series-type feed network just composes of two double-sided couplers which have been further reduced to a great degree by meandering the microstrips. the measured 10-db impedance bandwidth is 39% from 1.71 to 2.54 ghz, and the phase difference between two arbitrary adjacent ports is 90° ± 4.7° over the 1.75–2.35 ghz range. note that the measurements agree reasonably well with the simulations.
