ABSTRACT
Antenova, a developer of integrated RF devices, has introduced its Radionova line of fully integrated radio-antenna modules (RAMs). The company says the RAMs target the emerging market for small products requiring a small internal antenna by essentially integrating all of a handset's front-end RF components. According to the company, the modules, designed to sit easily atop the baseband chip, can significantly reduce the cost and complexity of adding wireless connectivity to mobile phones, laptop PCs, and other consumer electronics devices. The modules have been specifically designed to work across multiple wireless protocols and cover the GSM 900, 1800, and 1900 bands. The manufacturer's patented dielectric balanced antenna technology enables RF performance to be independent of the module's surroundings, even when applied to multiband designs. Antenna impedance is virtually independent of the ground-plane length. Less pcb real estate is required since the antenna works over the top of the other components. The company claims the module alleviates the problem of unbalanced antennas, whereby half the device sits on the chassis and the other monopole half sits near the ground planes, which can significantly impair antenna performance. According to the company, the module's "selfcomplementary" balanced antennas work with a full ground plane and do not need a chassis.
