Microwave gain horn antennas feature lightweight construction

Link Microtek, the manufacturer of RF and microwave components and subsystems, has introduced a new series of lightweight microwave gain horn antennas that have been specifically designed for use in military airborne applications.

Featuring a thin-walled aluminium construction, the AM-LHA series horn antennas are half the weight of standard aluminium gain horns and only a fifth of the weight of traditional brass alternatives. They provide a mid-band gain of 20dB and are available with rectangular waveguide inputs ranging in size from WR650 to WR28, covering microwave frequencies from 1.2 to 40.0GHz.

Fabricated from flat metal sheet to provide superior repeatability and accuracy, these precision-engineered horns come as standard with an Iridite coating and a choice of paint finishes. Wall thickness is just 1mm, while horn lengths range from 84mm for the 40GHz model to 1989mm for the 1.2GHz model.

The horn antennas can be supplied with a variety of waveguide-to-coaxial adapters, and Link Microtek also offers a custom design service to satisfy individual requirements for parameters such as gain, beamwidth and frequency coverage.

A medal for mobile medicine?
Medical services the world over are coming under great pressure to deliver high-quality healthcare and, at the same time control costs. Alongside this, patients are becoming far more involved in their wellbeing as well as wanting a high standard of healthcare with even greater convenience than before. As people are more mobile these days, mobile healthcare (mHealth) avoids the need to visit the doctor’s office and allows patients to provide health data to providers, as well as receive care, anywhere on the planet.
