摘要： In a U-shaped deformed folded dipole antenna, a first parallel section having a feeding point includes first and second L-shape sections, and a second parallel section without a feeding point includes first and second opposing side portions and a connecting side portion coupling ends of the first and second opposing side portions. Portions of the first and second L-shape sections arranged in parallel with the first and second opposing side portions have a width W1. Portions of the first and second L-shape sections arranged in parallel with the connecting side portion have a width W2. The first and second opposing side portions have a width W3. The connecting side portion has a width W4. An impedance of the deformed folded dipole antenna is controlled by setting the width W2 to be larger than the widths W1, W3, and W4.

摘要： A vehicular combo antenna apparatus including multiple antennas received in a housing is disclosed. The multiple antennas include a first antenna for short range communication and a second antenna. The first and second antennas are different in directivity and are arranged along a vehicle front-rear direction. The first antenna is located to have an inclination relative to a horizontal direction, so that: a portion of the first antenna distant from the second antenna is located above another portion of the first antenna in a vertical direction; and a radiation element part of the first antenna is located above the second antenna in the vertical direction. The second antenna is located on a radio wave radiation side of the first antenna.
