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-...

In this work, a dynamic analysis of the V line is presented. Previous work analyzed the performance of this structure for low frequency applications using quasistatic approximations. Here, we extend the analysis of the V line into the higher frequency range where dispersion becomes significant and where it cannot be predicted by quasistatic methods. We show that the V line provides features and...

analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form greens functions is presented. integral equations are derived from applying the boundary conditions on the radiating patch, across the aperture, and on the microstrip feedline. the computation of space domain greens functions is performed using the closed-form. the solution of the integral equatio...

A double-layer loaded on the octagon microstrip yagi antenna (OMYA) at 5.8 GHz industrial, scientific and medical (ISM) Band is investigated in this paper. The consist of two double positive (DPS) substrates. OMYA overlaid with a configuration were simulated, fabricated measured. good agreement was observed between computed measured results gain for antenna. According to comparison results, it ...

This paper studies the effect of dielectric cover layer thickness on circular microstrip patch antenna parameters such as gain, bandwidth, beam-width, radiation patterns, return loss and VSWR. The proposed is designed with 2.4GHz frequency in S-Band region. operating useful ISM band applications. Circular cavity model analysis simulated using HFSS simulation software (Electromagnetic simulator)...

Characteristics of a single-layer, dual-frequency microstrip patch antenna, which uses a T-strip loaded rectangular microstrip patch, are studied. This antenna is easy to achieve good impedance matching at both frequencies by tuning the feed position and other design parameters. Another advantageous aspect is that it has high polarization purity. A detailed parameter study is performed and the ...
