Methods and apparatus for a tunable dual spectrum antenna aperture including a RF antenna having first and second portions, wherein the first portion comprises a photoconductor material having a conductive state and a non-conductive state, and an IR sensor to detect IR energy. The state of the first portion determines a size of the RF antenna.

An antenna structure includes a housing, a feeding portion, and a connecting portion. The housing defines a gap and a groove. The housing forms a radiating portion and a coupling portion through the gap and the groove. A portion of the housing between the feeding portion and the gap forms a first radiating section. The connecting portion is electrically connected to one end of the coupling portion adjacent to the gap. When the feeding portion supplies current, the current flows through the feeding portion and the first radiating section, and is coupled to the connecting portion through the gap to activate a first operating mode. When the feeding portion supplies current, the current flows through the feeding portion and the first radiating section, and is coupled to the coupling portion through the gap to activate a second operating mode.

An electronic device may include ground structures and peripheral conductive housing structures defining opposing edges of a slot element. A monopole element may overlap the slot element. The monopole element may be directly fed radio-frequency signals by an antenna feed coupled to the monopole element. The monopole element may radiate the radio-frequency signals in a first frequency band while indirectly feeding the radio-frequency signals to the slot element via near-field electromagnetic coupling. The slot element may radiate the radio-frequency signals in a second frequency band that is lower than the first frequency band. The monopole element and the slot element may collectively form a multi-band antenna that exhibits a relatively wide bandwidth.

An antenna apparatus for a mobile terminal is provided. The antenna apparatus includes an antenna pattern, a first electric circuit and a second electric circuit respectively connected between both ends of the antenna pattern and a system ground, and a third electric circuit disposed between the antenna pattern and a feeding line, wherein the first electric circuit and the second electric circuit extend electrical wavelengths of the antenna pattern and the third electric circuit increases input impedance matching.

A multi-layer software controlled antenna. A radiating patch is provided over a variable dielectric constant (VDC) plate. Variable DC potential is applied across the VDC plate to control the effective dielectric constant at various locations of the VDC plate. RF signal is coupled between a feed patch and a delay line, and the delay line couples the RF signal to the radiating patch. The radiating patch, VDC plate, delay line, and feed patch are each provided at a different layer of the antenna, so as to decouple the RF and DC signal paths. A controller executes a software program to thereby control the variable DC potential applied across the VDC plate, thereby controlling the operational characteristics of the antenna.

An antenna array for use in a passenger vehicle. Four of the roof support pillars are used as antenna elements. Each of the four pillars is electrically connected or coupled to one end of a corresponding meanderline component. The other end of each meanderline is in turn coupled to a radio receiver, typically through a combining network.

Various embodiments provide an antenna device that includes: a metal member configured to have a length that contributes to at least a part of an electronic device; a printed circuit board (PCB) configured to be feed-connected to a preset position of the metal member in order to apply the metal member as an antenna radiator; and at least one electronic component electrically connected to a position different from the feeding position of the metal member and grounded to the PCB, and provide an electronic device that includes the same.
