Controlling the scan rate of frequency-scanned antennas can be useful for any bandwidth-limited application. Two techniques to control the scan rate of planar periodic leaky-wave antennas are discussed: optimizing unit cell dispersion and meandering unit cells with a desired periodicity. Each technique presents a tradeoff of limited matching bandwidth or reduced antenna gain, respectively. These techniques are used together to design a broadside-scanning Ka-band antenna. Measurements demonstrate a very high scan rate of 10.5 ° /%BW. The 8$%$ available bandwidth and 80 ° scan range through broadside is very favorable for frequency-scanned applications.
