Problem Statement
Ginger is a bidirectional data routing system. These quad antennas will provide a signal straight-down from the drop probe to the ground team. These antennas should not be used if there is a danger of high winds as the tracking team would not be able to keep directly under the probe. These antennas have a gain of around 8dBi, and a 3dB nose of about 60 degrees.
The design consists of a quad driven element and a quad reflector.
*Note: the reflector can be ommited for a more simple design at the cost of about 2-3DBi (a more omni-direcitonal design).

Dimensions
V1
The deisgn has been optimized for 915MHz using NEC2. The dimensions are as follows:
DE=8.446cm Side length of the driven element
RE=8.816cm Side length of the reflected element
D1=4.91cm Distance between the two elements
