Radar Today

Twenty years ago in Microwave Journal we wrote about “Radar in Transition.” The article opened with the statement that “radar engineers, at the end of 1984, find their field in transition between the conventional designs of the post World War II era and the digitally controlled, solid-state systems that...

A Compact Thin-film WLAN Antenna Switching Module

Miniaturization and cost reduction along with ever expanding user functions are important features for modern consumer communication devices as customers demand more data throughput at low cost. System-on-chip (SoC) and system-in-package (SiP) have brought more and more circuits and functions together. For passive circuits, traditional multi-layer printed circuit boards...

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...
