1. An antenna arrangement comprising:
- a first antenna element having a first low band resonant frequency, a first high band resonant frequency, and a first feed for connection to radio frequency circuitry; and
a second antenna element, separate to the first antenna element, having a second feed, wherein the second antenna element and the second feed, in combination, have a second low band resonant frequency and a second high band resonant frequency, wherein the second feed is connected to the first feed at the first antenna element, wherein the second feed comprises a phase delay element, wherein the second antenna element loads the first antenna element to provide multi-band resonant frequency operation, wherein the first and second feeds are configured to receive a common frequency band.
