Abstract
A directional antenna assembly includes a reflector and a director disposed on opposite sides of an antenna radiator element to minimize body loading effects and thereby maximize available antenna gain. The radiator is disposed in a first casing, and the reflector and director are disposed in a second casing selectively enageable with the first casing. In one arrangement, the position of the reflector and director relative to the user is adjustable to accommodate the position of the communications terminal relative to the user. In other arrangements, the directional structure is selectively enageable and disengageable with the antenna radiator.
Claims20
An antenna for a communications device, comprising:
- a radiator mounted in a first casing for sending and receiving an RF signal;
- a reflector mounted in a second casing;
- and
- a director mounted in said second casing, wherein said first casing and said second casing are independent of each other such that said radiator is not mounted in said second casing, and wherein said first casing and said second casing are selectively positionable relative to each other.
An antenna for a communications device, comprising:
- a radiator mounted in a first casing for sending and receiving an RF signal;
- a reflector mounted in a second casing;
- and
- a director mounted in said second casing, wherein said first casing and said second casing are selectively engageable with each other, wherein said radiator is molded in said first casing, and wherein said reflector and said director are molded in said second casing.
An antenna for a communications device, comprising:
- a radiator mounted in a first casing for sending and receiving an RF signal;
- a reflector mounted in a second casing;
- and
- a director mounted in said second casing, wherein said first casing and said second casing are selectively engageable with each other, and wherein said second casing is molded from a bendable thermoplastic material, said second casing, said reflector and said director being displaceable between a bent retracted position, in which said second casing is disengaged from said first casing, and a substantially straight extended position, in which said second casing is engaged with said first casing.
An antenna for a communications device, comprising:
- a radiator mounted in a first casing for sending and receiving an RF signal;
- a reflector mounted in a second casing;
- and
- a director mounted in said second casing, wherein said first casing and said second casing are selectively engageable with each other, wherein said first casing and said second casing are independent of each other such that said radiator is not mounted in said second casing, and wherein said second casing is substantially U-shaped having sides and a connector between said sides defining an opening therebetween, said first casing being selectively disposed in said opening.
A communications device, comprising:
- a device housing;
- a printed circuit board (PCB) mounted in said housing;
- and
- an antenna coupled with said PCB, said antenna including:
- a radiator mounted in a first casing for sending and receiving an RF signal,
- a reflector mounted in a second casing, and
- a director mounted in said second casing, wherein said first casing and said second casing are independent of each other such that said radiator is not mounted in said second casing, and wherein said second casing is selectively displaceable between an engaged position and a disengaged position.
