A Low Profile Multi-band U-shaped Aperture-coupled Microstrip Antenna with a Coil

In this article, an L-shaped probe-fed, U-slot patch antenna with a coil element is studied. The L-shaped probe feed is used to enhance the impedance matching, which is necessary because of a low radiation resistance in the usable band. The coil contri...
January 17, 2007
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,...

Dual-band Assembly of Integrated Short Backfire Antennas

A dual-frequency assembly of two short backfire (SBF) antennas, one large for low frequencies (LF) and one small for high frequencies (HF), is described in this article. The two antennas are located on the same axis and, since they have a common reflec...
January 16, 2007
The short backfire (SBF) is a highly effective aperture antenna of simple and compact construction. Basically, it consists of three elements: two parallel reflectors, large and small, spaced a half-wavelength apart, which form a leaky resonant cavity, and a cavity feed (half-wave dipole, 1–3 waveguide or horn, 4,5 or...

Broadband Design of a Small Non-symmetric Ground λ/4 Open Slot Antenna

The broadband design of a small size, λ/4 open slot antenna is investigated. By properly choosing the dimensions of the open slot and of the rectangular conducting plate, which is connected to the end of the 50 Ω microstrip-line feed, a broad...
January 16, 2007
The wireless communication industry is developing rapidly and wireless communication products, PDAs, laptops and cell-phones are becoming a necessity of life. Communication systems need a wide frequency bandwidth to transmit and receive multimedia information at high data rates. Mobile wireless communication products must be easily portable and cheap to...

The Use of Broadband Military Antenna Technology in Modern Communications Systems

January 12, 2007
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...
