Abstract
Quad-slot antenna structures of user devices and methods of operating the user devices with the quad-slot antenna structures are described. One apparatus includes a RF feed coupled to a quad-slot antenna, including a first slot and a second slot and a third slot and a fourth slot. The first slot and the second slot are driven elements and the third slot and the fourth slot are parasitic elements.
Claims17
A user device, comprising:
- a circuit board comprising a transceiver and a ground plane;
- a radio frequency (RF) feed coupled to the transceiver;
- and
- a quad-slot antenna coupled to the RF feed and formed as slot openings in the ground plane, wherein the quad-slot antenna comprises:
- a first monopole open slot;
- a dipole closed slot;
- an open slot;
- and
- a second monopole open slot, wherein the first monopole open slot and the dipole closed slot are driven elements and the open slot and the second monopole open slot are parasitic elements, wherein the open slot is a hybrid open slot configured to radiate electromagnetic energy as a monopole open slot in a first configuration and as an L-shape monopole in a second configuration.

An apparatus comprising:
- a radio frequency (RF) feed;
- and
- a quad-slot antenna coupled to the RF feed, the quad-slot antenna formed as slot openings in a metallic member, wherein the quad-slot antenna comprises:
- a first slot;
- a second slot;
- a third slot;
- and

5 more elements
A method of operating a user device, the method comprising:
- inducing a first current at a radio frequency (RF) feed coupled to a quad-mode antenna, wherein the quad-mode antenna comprises:
- a first slot;
- a second slot;
- a third slot;
- and
- a fourth slot, wherein the first slot and the second slot are driven elements and the third slot and the fourth slot are parasitic elements;
- in response, parasitically inducing a second current at the third slot and a third current at the fourth slot, wherein the first slot and the second slot operate as feeding structures to the third slot and the fourth slot;
- and
- radiating electromagnetic energy from the first slot, second slot, third slot, and fourth slot to communicate information to another device in response to the first current and the second current, wherein the radiating the electromagnetic energy comprises:
- radiating the third slot as a monopole open slot in a first configuration;
- and
- radiating the third slot as an L-shape monopole in a second configuration.
