Apparatus and techniques described herein can provide enhanced wireless communication range for a wireless device without requiring additional external active circuitry, such as using a simple mechanical and electrical configuration as compared to using an active antenna booster device. Generally, the apparatus and techniques described herein can be used to enhance a directivity of a wireless device antenna using a passive attachment. For example, a directivity of a first antenna can be enhanced without substantially affecting the directivity or performance of another antenna on or within the wireless device.
