abstract

  • The suppression of parallel plate and cavity modes in shielded microstrip circuits is presented. To this aim a textured metal lid consisting of periodically located pins known as a bed of nails is
    employed. The mode suppression has a bandwidth of more than 2:1, and it
    does not interfere much with the microstrip circuit. Thereby, this mode
    suppression technique introduces a new advantageous packaging technology
    for high frequency circuits.
