An improved antenna includes a dielectric body arranged entirely or mostly (e.g., with more than 40% such as more than 50% or 60% of its volume and/or of its weight) underneath antenna radiating elements provided for lower frequency operation; and entirely, or mostly (e.g., 40%, 50% or 60% of its volume and/or of its weight) above antenna radiating elements provided for upper frequency operation. |
