A Broadband $L$ -Strip Fed Printed Microstrip Antenna

A broadband <;i>;L<;/i>; -strip fed printed microstrip antenna is presented. The strip loaded slotted broadband microstrip antenna is fed by an
L
-strip feed line to achieve impedance matching for the higher order modes of the patch antenna in addition to the existing resonances. The antenna offers 74% bandwidth when printed on a substrate of dielectric constant 4.2 and has an overall dimension of 42 × 55 × 3.2 mm
³
. The simulated and experimental reflection characteristics of the antenna with and without the
L
-feed along with radiation patterns, input impedance variations, gain and efficiency of the final antenna are presented and discussed. The time domain transient analysis indicates a minimum dispersion to the transmitted pulse.
