Title:
INSECT TACTILE DIPOLE ANTENNA, DIRECTIONAL ANTENNA, AND AREA CONTROL ANTENNA
Document Type and Number:
WIPO Patent Application WO/2003/050916
Kind Code:
A1
Abstract:
An antenna which hardly generates a reflected wave in a connected supply cable. An insect tactile dipole antenna (110) comprises a first antenna section (110), second antenna section (112), first supply point (21), and second supply point (22). The first antenna section (111) comprises a first element (A) and second element (B). The first element (A) has a first side (1) and second side (2). The first side (1) keeps one end connected to the first supply point (21) and extends linearly with a tilt of almost 45ºC clockwise to the Z−axis positive direction. The second side (2) extends almost in parallel with the Z−axis positive direction from the other end of the first side (1). The first side (1) and second side (2) each have an almost 1&sol 8−length of a wavelengh. The second supply point (22) and second element (B) are each located close to a position of the first supply point (21) and first element (A) rotated by almost 180º on the reference line (L) extends in the Z−axis direction. The second antenna section (112) is located close to a position of the first antenna section (111) rotated by almost 90º on the reference line (L).
