✦ Synopsis

Figure 4 Measured two-tone intermodulation distortion of the link in Figure 1. The measured third-order intercept point is 16 dBm. The total received photocurrent was 50 mA. The two input tones were at 135 and 171 MHz providing complementary outputs to allow balanced photodetection techniques to be used for noise cancellation.

## Abstract A high‐directivity microstrip array using multilevel elements based on fractal geometry is theoretically compared with an array using circular patches. Within the same electrical area, the same directivity can be obtained. However, the number of elements for the fractal‐based array is 2
