Mid-air collisions (MACs) are commonly caused by temporary or permanent loss of flight
control resulting in catastrophic damages and hence must be countered with suitable …

In this paper, a unique negative refractive index-metamaterial (NRI-MTM) structure is
proposed for traffic alert and collision avoidance system (TCAS) for aircraft application. The …

In this paper, a transmission type negative refractive index metamaterial surface acting as a
planer surface lens is presented. A measured 3 dB transmission band of 2 GHz from 8.55 …

We present a new development of microstrip antenna structure combining a simple circular
structure with a ring antenna structure as the parasitic element to improve the antenna gain …

Traffic alert and collision avoidance system provides a solution to reduce the threat of mid-
air collisions between civil aircraft. The endfire antenna is very much essential in such …

This article presents 3× 3 Electromagnetic Band Gap (EBG) array mounted on top of a
truncated slotted square patch antenna for gain and radiation and aperture efficiency …

In this paper, a unique negative refractive index-metamaterial (NRI-MTM) structure is
proposed for traffic alert and collision avoidance system (TCAS) for aircraft application. The …

Traffic alert and collision avoidance system (TCAS) is an airborne electronic equipment that
is used to avoid mid-air collisions between two civil aircraft. In the existing TCAS system, four …
