First Claim
Patent Images
1. An antenna arrangement for a multimode communication device, comprising:
- a first antenna operational in a low band below 1000 MHz and in at least predetermined use modes in high bands above 1500 MHz;
a second antenna operational in the high bands;
a VSWR tuner coupled to the first antenna; and
a controller coupled to the VSWR tuner.

Abstract
A multimode communication device (10 or 50) having an antenna arrangement (14 or 54) having a first antenna (18) operational in both low bands and high bands, a second antenna (20) operational in high bands, a tuner (26) coupled to the first antenna adapted to adjust matching elements to modify return loss to lower reflected power, a switching mechanism (28) for selecting between the first antenna and the second antenna, and a controller (30) coupled to the switching mechanism and the tuner.
