Abstract: An ultra-broadband antenna system is disclosed. The antenna system is a single tubular antenna structure comprising an asymmetrical dipole fed with a biconical dipole. The biconical dipole covers the high frequency spectrum, while the asymmetrical dipole covers intermediate frequencies. The invention further relates to a combination of the two dipole structures such that together they act as a monopole to cover the low frequency spectrum. A first RF connector attaches to the asymmetrical dipole and the biconical dipole, and a second RF connector excites the combination of the two dipoles as one large monopole. A choke minimizes interference between the asymmetrical/biconical dipoles and the monopole. The resulting frequency span is greater than 500:1, providing operation over the range of 20 MHz to 10 GHz.

Abstract: An apparatus for carrying a car seat such as an infant car seat, child car seat, or a child booster seat is disclosed. The apparatus includes a carrier body and at least one system of harnesses for attaching to the car seat, and for securing the apparatus on a person's back, chest, or side, leaving the person's hands free. The system of harnesses may include an upper harness system, a middle harness system, a lower harness system, a shoulder harness system, and a hip harness system. The apparatus permits a person to carry the car seat together with a child secured in the car seat.
