A Design Procedure for a Circular Polarized, Nearly Square Patch Antenna

This article describes the design of a compact, circular polarized (CP), nearly square patch antenna using an offset microstrip feed and operating at 2.45 GHz. The effect of the offset on the perturbation segment and the design of a simple matching net...
In order to obtain circular polarization, a dual feed can be used to excite a square patch to generate two fundamental modes, TM 10 and TM 01 , radiating at the same frequency. To meet the necessary conditions for circular polarization, the two modes must be equal in magnitude...

A New Year, a New Look, the Same Mission

We start this New Year with several new features to Microwave Journal, and one long-standing mission.
I’ll begin with the changes, since you’ve probably noticed the most obvious of them already. Yes, the cover has a new look and a new direction. The cover graphic will now reflect the editorial theme for the issue, as illustrated in this month’s “Radar/Antennas” focus. Less obvious, but no...
