Patent number: 6661391Abstract: An antenna is capable of transmitting/receiving waves in multi-ranged frequency bands, and providing high antenna gain, reliability and productivity. A radio communication apparatus uses the antenna. A feed portion is electrically connected with an antenna element portion at one end, and with radio-frequency circuitry of the apparatus at another end. A dielectric material core rod mechanically supports the antenna element portion. A dielectric material radome partially covers the antenna element and feed portion. The antenna element portion is formed from an approximately helical-shaped portion and an approximately meander-shaped portion, both of which are made from a thin-belt-shaped conductive plate and concentrically arranged on the core rod. Properly adjusting of the approximately helical-shaped and the approximately meander-shaped portions can provide impedance characteristics optimal for multi-ranged frequency bands.Type: GrantFiled: May 1, 2002Date of Patent: December 9, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masahiro Ohara, Toyoshi Fukumura
