For the purpose of enhancing the gain of a printed end-fire antenna with broad bandwidth, we propose the non-resonant meander-line (ML) based artificial material and place it in front of the antenna.
In Section 2, the effective parameters of the proposed material are retrieved, the reasons for gain improvement by the proposed material are investigated, and for an end-fire antenna, the enhanced gain by a dielectric lens and the ML-based material are compared.

TSA is a planar end-fire antenna
and is often used for microwave/millimeter-wave imaging, sensors, and phased arrays .
The comparison between simulated and measured results shows that the proposed LPDA can be used as an Ultra Wideband Antenna in the range 4.25-13.25 GHz, and as a wideband end-fire antenna in the whole operating bandwidth (4-18 GHz).
The simulated and measured results show that the proposed LPDA can be successfully used as a wideband end-fire antenna in the whole operating bandwidth (4-18 GHz), and as an Ultra Wideband Antenna in the range 4.25-13.25 GHz, i.e., in a relative bandwidth greater than 100%.
As a typical printed UWB end-fire antenna, the Vivaldi antenna has both the advantages of printed antennas and end-fire antennas [10, 11], which results that it is widely used for satellite communication, remote sensing, microwave imaging, wide band scanning arrays and military applications.

We observe (Figure 8) that for the end-fire antenna
configuration, the total power loss (in comparison with 1/r propagation model) might be as high as 3 dB at the antenna separation of 5 mm.
In this paper, we adopt a new Competitive Algorithm of Simulating Natural Tree Growth to design a conformal end-fire antenna
confined to a cross structure, which usually appears in aerospace vehicles.
The end-fire antennas
are held in slots along the exterior of the radome (our current method of fixing the antennas is described in further detail in Subsection 4.1).
 The transmitter power is fed to an array of end-fire antennas
in the rotodome via a duplexer.
