Study on the characteristics of capillary plasma antenna array in radio wave

Abstract

Recently the new type of plasma antenna shows explosive increment in the antenna development which demands the new elements, the new designs and wide band of resonance frequency in microwave range. Hence, a new approach solution such as the small radius capillary tube with specific gas pressure and the line array pattern emerged to fulfill the requirement of plasma antenna especially wide band microwave range. Some designs of capillary tube with different radius such as 2.0 mm, 4.0 mm, 6.0 mm, 8.0 mm and 10.0 mm that contained the mixture mercury-argon gas pressures, 10 Torr and 20 Torr are created by using CST Microwave Studio.
