1. A transmission/reception element comprising:
- a plurality of metal layers disposed on a substrate and spaced apart from each other;
a switch configured to control electrical coupling between the plurality of metal layers, wherein the switch comprises a contact-point group including a plurality of contact-point pairs each arranged along a movable member disposed in a cavity formed between a pair of the plurality of metal layers; and
a drive section coupled to the contact-point group via the movable member and configured to mechanically drive the contact-point group in order to switch a state of each of the plurality of contact-point pairs between in-contact and no-contact,wherein the movable member is coupled to one end of the drive section and configured to slide in a direction along which the contact-point pairs are arranged,wherein the movable member is provided with a plurality of bars at another end,wherein the contact-point pairs are each provided with a fixed contact point provided on each of the plurality of the metal layers, and a movable contact point provided to each of the plurality of bars of the movable member,wherein a wall surface of the cavity is shaped with one or more concavities and one or more convexities to match a shape of the movable member.

Abstract
A transmission/reception element includes: a plurality of metal layers each disposed with space from another; and a switch for controlling electrical coupling between the metal layers. The switch includes a contact-point group including a plurality of contact-point pairs each disposed in parallel between each two of the metal layers, and a drive section mechanically driving the contact-point group for state change of each of the contact-point pairs between in-contact and no-contact.
