Cavity-backed T-fed slot antenna

Cavity-backed slot antennas are experiencing a revival because of the ever-increasing need for low-profile and conformal antennas which have a low radar cross section out of their operating frequency bands. Like thin microstrip patch antennas, cavity-backed slot antennas typically have a narrow impedance bandwidth of 1 to 6 percent of center frequency, which limits their usage. A new method of feeding a thin cavity slot antenna with a stripline leading to a T-bar, which lies beneath or in the slot, greatly enhances the impedance bandwidth over a range of 10 to 30 percent depending on the slot width.
