Abstract: A wireless subscriber communication unit (200) comprises a transmitter (220) and/or receiver (210) coupled to an antenna arrangement for transmitting/receiving electromagnetic signals. The antenna arrangement comprises an internal antenna 330 located within the wireless communication unit, and an external antenna 202 located outside the unit, such that both the internal antenna and the external antenna co-operate on substantially the same electromagnetic signal. The provision of both an internal and an external antenna enables the wireless subscriber communication unit to function adequately should an antenna become disconnected, malfunction, or its performance suffer from impedance mismatching. The internal and external antennas are preferably configured to be orthogonal to each other, thereby providing the wireless subscriber unit with the ability to operate with a substantially circular or elliptical polarization. A second internal antenna 360 may be included to enhance the transmission/reception efficiency further.

Abstract: A multi-frequency band antenna ( 100 ) includes a dual-pitch coil ( 120, 130 ), and a top insert ( 140 ), operably coupled to an antenna base ( 105 ). The multi-frequency band antenna ( 100 ) is configured to radiate electromagnetic signals at a lower frequency 230 ) of multi-frequencies using substantially the whole of the dual-pitch coil ( 120, 130 ); and at a higher frequency ( 240 ) of said multi-frequencies using a length of said antenna base ( 105, 110 ) and a portion of said dual-pitch coil ( 120 ). A first portion of the dual-pitch coil has a longer pitch than a second portion of the coil and the first portion has a first end attached to the antenna base and a second end attached to the second portion, and the second portion has an effective electrical length substantially equal to a wavelength (lambda) of radiation having a frequency corresponding to a frequency in the second band.
