材料カタログ
Antenna Toolbox™ には、金属材料および誘電体材料のカタログが用意されています。さまざまな種類の材料を使用してアンテナとアンテナ アレイを構成できます。電磁損失、機械的強度、熱特性などを考慮して、アンテナ材料を選択します。電気損失を考慮する場合、散逸率と誘電率の値が重要になります。電気損失は、放射電力の低下、リターン ロス共振の広がり、高電力レベルにおける熱の影響など、アンテナの性能低下を引き起こします。

Multiband Nature and Miniaturization of Fractal Antennas
Analyze the multi band characteristics of fractal antennas and compare the size of fractal antennas with conventional antennas. The term fractal means irregular fragment. A Fractal is a rough or fragmented geometric shape that can be subdivided in parts, each of which is a reduced size of the whole. Fractal geometries are applied to antenna elements which aids in creating antennas of compact size and multi band behavior. These characteristics are required in small and complex circuits. Fractal antennas are multiband, high gain, low profile antennas. They are compact relative to the conventional antennas because of their efficient space filling nature.
Design Log-Periodic Sawtooth Planar Antenna for UHF Ultra-Wideband Applications
Create, model, and analyze two-arm log-periodic sawtooth planar microstrip antenna [1]. It is a bowtie-like antenna that consists of two arms located on the square-shaped FR4 dielectric substrate. This example designs a log-periodic sawtooth planar antenna with stable impedance over a wide bandwidth from 300 MHz to 1200 GHz. This antenna is widely used in the ultra high frequency (UHF) range and for ultra-wideband (UWB) systems such as ground penetrating radar systems (GPRs). The non-evasive and nondestructive technique in GPRs uses electromagnetic radiation in the microwave band. GPRs use high-frequency radio waves, usually in the 10 MHz to 2.6 GHz range.
