A single element linearly polarized (LP) aperture coupled microstrip patch antenna (ACMPA) in microwave frequency band is presented in this paper. The paper starts with the requirement for developing a low profile, low cost, lightweight, wideband LP antenna suitable for commercial chipless RFID tag readers. Then, a thorough review is done on existing low profile wideband antenna designs to find out a suitable match with all required reader antenna specifications. From the literature analysis, ACMPA design technique is found as the best match for developing the reader antenna, which is followed next. First, antenna specifications are listed for developing a single element LP ACMPA. Then, a single element is designed and optimized to achieve the targeted values, which is fabricated and assembled next. After that, this ACMPA is measured in a vector network analyzer (VNA), which fulfills the set targets. Next, tag reading performance of the antenna in three different measurement setups is evaluated through measurement of 'O' slot loaded orientation insensitive (OI) tags. These tag measurement results have confirmed the usability of the developed antenna in commercial tag reader.
