    • A diode in a semiconductor body has two laterally adjacent regions. Each region has buried portions. The first and second regions are doped with opposite conductivity type dopants. A buried P-N junction exists where the buried portions meet. Since the junction is buried, surface breakdown effects are greatly reduced. The lateral orientation provides for easier series connection or several such diodes. A method for making a diode in a body comprises forming two laterally adjacent buried portions of respective opposite conductivity type regions. A contact portion of at least one region is formed extending to the surface of the body.

    • A patch antenna, which may be one element of an antenna array, is formed on one broad surface of a semiconductor plate. A ground plane is formed on the second broad surface. This semiconductor is doped in regions near a periphery of the patch to define a semiconductor PN junction have electrode contacts to the patch and to the ground plane. The junction has capacitance which tunes the patch antenna. The characteristics of the junction are controlled by bias to selectively tune the patch antenna. The bias is a direct voltage in one embodiment of the invention. In another embodiment, the junction work function itself provides a bias which is controlled by temperature control of the diode.

    • Antennas chiefly intended for microwave and millimeter-wave use include geometric-shaped conductive patches on one broad surface of a planar semiconductor substrate. The other broad side of the substrate bears a conductive ground plane. Monolithic PIN diodes are formed by doping the substrate at various points between the conductive patch and the ground plane. Biasing arrangements affect the conduction of the PIN diodes thereby affecting or tuning the optimum operating frequency, the radiation pattern, and/or the impedance of the antenna. In a particularly advantageous configuration, the PIN diodes have lateral dimensions greater than or equal to one-tenth wavelength (.lambda./10) at the operating frequency. Distributed diodes have lower resistance and reactance than discrete or discrete monolithic diodes, thereby providing improved radiating characteristics, and have a relatively large power-handling capability which makes them useful for power transmission.

    • An electrical short-circuit for alternating-current (ac) microwave signals is physically positionable in direct response to an electrical bias control without an intermediary electromechanical converter. The electrically positionable short circuit includes at least first and second doped regions in a semiconductor, separated by a region in which the short circuit is formed between the doped regions by the bias. A first embodiment comprises discrete diodes connected between conductors at different locations, the discrete diodes having different forward junction voltages, so that varying the common bias voltage varies the number of conducting diodes and thus positions the short circuit in a stepwise manner. A FET embodiment includes various discrete MOSFETs having different conduction threshold voltages, and having their sources and drains connected at various points to the conductors to be short-circuited, so that variations of a common gate bias voltage selectively render one or more of the FETs conductive, thereby stepwise positioning the short-circuit. Distributed PIN and MOSFET structures provide continuous short circuit positioning as a monotonic function of bias. Two distinct modes of operation, pinchoff/resistive and a resistive/below-threshold are possible for the distributed FET embodiment. The electrically positionable short-circuit can be coupled to the conductors of a transmission line for effecting tuning, or can be coupled to a transmission line in such a way as to vary the signal path length and thereby provide phase shift.
