Broadband polarization diversity antennas
First Claim
1. An antenna comprising:
- a baseboard with a baseboard-feed line that includes a serpentine meander-line portion; and
an antenna-array board with two or more antenna elements, each antenna element having an associated frequency, the two or more antenna elements arranged in a series on the antenna-array board, the antenna-array board attached to the baseboard with the serpentine meander-line portion located between an edge of the antenna-array board and the baseboard and each antenna element connected to the serpentine meander-line portion via an antenna-feed line located on the antenna-array board,wherein a length of each segment of the serpentine meander-line portion between two antenna-feed lines of adjacent antenna elements is inversely proportional to a larger of the two frequencies associated with the two adjacent antenna elements and two adjacent antenna elements with one of the two antenna elements connected to an end of the serpentine meander-line portion have the same associated frequency.

Abstract
This disclosure is directed to broadband polarization diversity antennas. In one aspect, a polarization diversity antenna includes a baseboard with a baseboard-feed line located on a first surface. The baseboard-feed line includes a serpentine meander-line portion. The antenna also includes an antenna-array board with two or more antenna elements arranged in a series. The antenna-array board is attached to the first surface with the serpentine meander-line portion located between an edge of the antenna-array board and the baseboard. Each antenna element is connected to the serpentine meander-line portion via an antenna-feed line located on the antenna-array board. The antenna array provides two dimensional polarization broadcasting and receiving of electromagnetic radiation. In another aspect, a notch antenna is formed on an opposing second surface of the baseboard opposite the antenna-array board in order to provide three-dimensional polarization broadcasting and receiver of electromagnetic radiation.
