Abstract
A printed meandering strip (PMS) is proposed for feeding a patch antenna. It is demonstrated that the impedance matching of the antenna can be further improved by using a higher order PMS. A patch antenna fed by a first order meandering strip has an impedance bandwidth of 22% [standing wave ratio (SWR) < 1.5], cross polarization level of less than -25 dB and a gain of 9 dBi. The measured impedance bandwidths of a second order PMS and a third order PMS are 12% (SWR < 1.2) and 8% (SWR < 1.1), respectively. They have an average gain of about 9 dBi and cross polarization levels are low In level. All measurements have been confirmed by simulation.
