An 8 element broadband antenna for AMPS+GSM applications

This paper presents an 8 element broadband antenna suitable for AMPS and GSM900 cellular BTS applications. The proposed antenna model consists of an array of two layer aperture coupled patches which are capacitively fed with a metallic microstrip feed. The design is suitable for applications requiring beam steering and results are presented for various elevational tilt angles. Furthermore, the proposed antenna has the advantages of ease of manufacture, low production costs, and is easy to recycle at the end of its useful life.
