Latest Patents

One of Maeda's latest patents is a phased-array antenna device. This device boasts a long operating life without mechanical parts, high spatial resolution, and the ability to perform microwave observation with broadband and high-frequency resolution. The phased-array antenna device utilizes direct A/D conversion through a band-pass filter (BPF) on an amplified antenna analog signal. It then conducts a second cross-spectrum calculation after converting the signal into complex frequency data through Fast Fourier Transform (FFT). To detect weak electromagnetic waves, the device repeatedly performs a second FFT over an extended period, culminating in integration.

Another notable patent is an AD converter designed for wideband noise signals. This converter can transform signals of several GHz or more into digital signals, even in constrained installation spaces and power supply conditions. The AD converter features a comparator that compares the input voltage of an analog signal to a determination voltage. It also includes an adjustment unit, an encoder for outputting time-series data, a processing unit for calculating the frequency of output codes, and a control unit that ensures the adjustment unit operates to achieve a predetermined calculation result.
