Webbet al., 1998]. The L-probe proximity-feed technique [Luk et al., 1998] compensates for probe inductance and extends the achievable impedance bandwidth for probe-fed patch antennas on thick ( 0.1 l o) low-permittivity dielectric substrates. Typically, this design yields 30% impedance bandwidth (SWR 2) and an average gain of 7.0 dBi. WebbProximity Coupled Feed. Another name of this technique is electromagnetic coupling technique. In this technique the feed line is placed between the two dielectric substrates … Webb17 mars 2024 · Different feeding methods also increase the antenna bandwidth such as proximity feed patch, asymmetric CPW fed patch antennas [10], [11].

"WebbThe broadband microstrip antenna (MSA) is realized by fabricating the patch on lower dielectric constant thicker substrate. However for substrate thickness (h) more than 0.04λ0, the bandwidth (BW) is limited by the feed probe inductance. For h > 0.06λ0, the BW is increased by using proximity feeding technique.
