Abstract
The disclosure concerns an antenna assembly having a substrate with an antenna radiating element and a ground conductor disposed on the substrate, the ground conductor further characterized by a plurality of ground resonators, wherein a length associated with each of the ground resonators increases as the ground resonators are distanced from the antenna radiating element. Additionally, a coaxial cable is routed around the antenna assembly for configuring the coaxial cable as an additional ground resonator associated with the antenna assembly. The resulting antenna provides wide band performance between 700 MHz and 2700 MHz with improved efficiency compared with conventional antennas.
Claims20
An antenna, comprising:
- a substrate comprising a top edge, a left edge, a bottom edge and a right edge;
- a radiating element supported by the substrate, with at least a portion of the radiating element being disposed proximate the top edge and the right edge;
- a ground conductor supported by the substrate, with at least a portion of the ground conductor being disposed proximate the left edge and the bottom edge, the ground conductor further comprising:
- a first ground resonator having a first length;
- a second ground resonator having a second length greater than the first length of the first ground resonator, the first ground resonator located between the second ground resonator and the radiating element;
- and
- a third ground resonator having a third length greater than the first length of the first ground resonator, the second ground resonator located between the third ground resonator and the first ground resonator.
