Latest Patents

1. **Power Efficient Feed Network for TACAN Antenna Arrays**: This patent outlines an advanced antenna feed designed for a TACAN circular array. It includes a power divider that separates a source of radio frequency signals into zero, first, and ninth order mode signals. Subsequently, a second power divider distributes the zero mode input signal into multiple output signals, each driving a pair of elements in the TACAN antenna array. The design incorporates a conventional matrix of radio frequency components that processes the first and ninth mode excitation signals, culminating in a phase combining network. This network combines the first and ninth mode signals to generate a range of output signals that effectively drive the antenna elements, resulting in the required azimuth antenna pattern for TACAN systems.

2. **Dual Phase Shifter**: This invention features a variable dual phase shifter that allows for simultaneous phase shift variations across two signal paths. The mechanism consists of two 90-degree hybrids linked by matching transmission lines. Variable-impedance radio-frequency devices, ideally p-i-n diodes, are strategically positioned along these lines to create reflective terminations. The phase shift for each signal is adjusted based on the position of these terminations from the hybrids. This innovative system is also designed to allow for cascading multiple phase shifters to achieve progressively finer adjustments in phase shift.
