A compact Ultra Wide Band (UWB) antenna with coplanar waveguide feed has been designed and results are verified in this paper. The antenna has been designed on FR4 substrate with dielectric constant (εr) of 4.4 and dimensions of 32mm x 26mm x 0.8mm. The presented antenna shows return loss characteristics in the band of 3.1 to 10.6 GHz as prescribed by FCC, USA. Parametric studies have been done...

A compact and simple design of a CPW-fed planar antenna for wireless sensor network antenna application with a better size reduction is presented. The proposed antenna consists of an inverted  shaped metal patch on a printed circuit board fed by a 50-Ω coplanar waveguide (CPW). The parametric analysis of length and width are made. The designed antenna’s physical dimensions are 32 mm (length) x...

Presence of Foreign object debris (FOD) at airport runways is an immense threat to flight safety. Such objects may cause potential damage to the aircraft especially during the take off and landing. This paper introduces the design of a low-cost Ka-band FOD radar sensor adopting state-of-the-art system-on-substrate (SoS) approach. Contrary to the reported single-layer SoS design approach, multi-...

Background: The original traveling-wave approach uses a remotely placed antenna to stimulate the propagation of two TE11 waveguide modes in circular polarization (CP) within a human 7 T scanner. While this approach enables large field-of-view imaging and provides free space around the subject, one major drawback is the small number of transmit/receive sensitivities (i.e. the two TE11 modes), wh...

We propose a novel optical hybrid plasmonic patch nano-antenna for operation at the standard telecommunication wavelength of 1550 nm. The nano-antenna is designed to be compatible with a hybrid plasmonic waveguide through matching of both the operational mode and the wave impedance. The antenna is designed to receive the optical signal from a planar waveguide and redirect the signal out of plan...

An efficient design procedure for a radial waveguide feed network for an array antenna, whose radiating elements are pin-fed, is presented. A model of the feed network is considered and relevant design parameters are expressed by simple analytic terms. To facilitate the design of the feed, a useful coupling chart for a pin-loaded radial waveguide is suggested. It shows graphically the dependenc...

A structure shaped substrate wideband microstrip patch antenna fed by coplanar waveguide (CPW) is proposed for wireless applications. Structure shaped substrate is produced by cutting the rectangle shape substrate in the form of a semicircular disc. The radiating patch of proposed antenna is taken in the form of Ushape. The ground plane is extended towards both sides of radiator for reducing th...
