Gallium Phosphide IMPATT Sources for Millimeter-Wave Applications

The potentiality of millimter-wave (mm-wave) double-drift region (DDR) impact avalanche transit time (IMPATT) diodes based on a wide bandgap (WBG) semiconductor material, Gallium Phosphide (GaP) has been explored in this paper. A non-sinusoidal voltage excited (NSVE) large-signal simulation method has been used to study the DC and high frequency characteristics of DDR GaP IMPATTs dsigned to ope...

Leaky CPW-Based Slot Antenna Arrays for Millimeter-Wave Applications

A uniplanar leaky-wave antenna (LWA) suitable for operation at millimeter-wave frequencies is introduced. Both unidirectional and bidirectional versions of the antenna are presented. The proposed structure consists of a coplanar waveguide fed linear array of closely spaced capacitive transverse slots. This configuration results in a fast-wave structure in which the = 0 spatial harmonic radiates...

Compact Dielectric Annular Grating Antenna for Millimeter-Wave Applications

This paper reviews a simple and compact dielectric annular grating antenna. The proposed antenna made of high resistivity silicon using silicon platform. The antenna is fed through Dielectric image guide (DIG), with a maximum gain of 18 dB, and wide bandwidth more than 7 GHz which is suitable for commercial applications, such as mobile radio, short range wireless communication and W-band applic...

Hybrid Array Antenna for Broadband Millimeter-wave Applications

A hybrid array configuration suitable for wideband millimeter-wave applications is presented in this work. The proposed structure is based on the use of circular waveguide elements electromagnetically coupled trough circular apertures to a stripline distribution network. The adopted excitation mechanism avoids the use of transition components generally reducing the overall antenna efficiency. S...
