An antenna having radio-frequency (RF) radiating antenna elements with static capacitors are described. In some embodiments, the antenna has RF signal source; a plurality of radio-frequency (RF) radiating antenna elements coupled to the RF signal source, wherein each of the RF radiating antenna elements comprises a slot, a tuning element coupled to the RF signal source and to tune the slot as part of the RF radiating antenna elements generating beams, and a fixed capacitor coupled to the RF signal source and coupled in series with the tuning element across the slot, the fixed capacitor to mitigate harmonic generation in order to control linear response of the plurality of radio-frequency (RF) radiating antenna elements.

Antenna aperture having antenna elements with static capacitors

Antennas with integrated varactor circuits are described. The antenna may comprise metasurface antennas. In some embodiments, an antenna comprises an array of antenna elements, wherein each antenna element comprises a iris and a varactor diode integrated on an integrated circuit (IC) chip coupled across a portion of the iris. The antenna can also comprise a plurality of transistors, each transistor coupled to a distinct one of the varactor diodes in the array of antenna elements to provide a tuning voltage to the one varactor diode.

Metasurface antenna with integrated varactor circuits

Methods and apparatuses for performing optical inspection of varactor diodes in an antenna are disclosed. In some embodiments, the method of testing an antenna having varactor diodes comprises: selecting a plurality of varactor diodes to be placed in a light emitting state; forward biasing the selected varactor diodes to a magnitude at which the selected varactor diodes are to emit light; and detecting one or more faulty varactor diodes of the selected varactor diodes based on their emitted light intensity.
