Microstrip patches are an attractive type of antenna because of their low cost, conformability and ease of manufacture. The aperture-coupled configuration 1 also provides the advantage of isolating spurious feed radiation by using a common ground plane. The primary barrier to the implementation of these antennas in many applications,...

The Use of Broadband Military Antenna Technology in Modern Communications Systems

Microwave Journal
No Comments
For many years, military applications have required broad bandwidth communication links, incorporating antennas that have a similar broadband capability. Often the antennas must operate over a frequency range of several octaves. Consequently, antenna structures that have multi-octave capability have been designed and manufactured and these techniques are now proving...
