Abstract

An active integrated antenna (AIA), which consists of a T‐shaped microstrip‐line‐fed slot antenna, is proposed. Since the designed antenna has an electromagnetically coupled feedback loop, it can easily solve the problem of DC isolation between ports of the amplifier. The fabricated parallel feedback antenna oscillator shows stable oscillation at a frequency of 10.05 GHz. The measured EIRP is 37.79 mW, and the cross‐polarization levels are at least −15‐dB lower than those of co‐polarization for all directions. © 2005 Wiley Periodicals, Inc.

extinction ratio could be increased further by a proper choice of splitting ratios of the couplers [10]. The wavelength resolution limit of the OSA also limits a precise measurement of the actual extinction ratio. The minimum possible change in the FSR during tuning of the MZI by this technique was

## Abstract In this letter, we experimentally study a T and a shunt‐stub‐shaped microstrip‐fed slot antenna backed by a ground plane. The proposed antenna has a frequency bandwidth of approximately 54% for __S__~11~≤−10 dB, centered around 2.5 GHz, with relatively good pattern characteristics. © 20

A model of the printed CPW-fed slot antenna based on the lossy transmission-line method is presented. An original field distribution inside the slots is proposed to compute the input impedance of CPW-fed radiating slot antennas. The theoretical and experimental results are compared successfully in t

An impro¨ed transmission line model for a single microstrip-fed slot element is extended to the case of a linear array with negligible interelement mutual coupling. S-parameter results obtained for two-, four-, and eight-element slot arrays fa¨orably compare with those from Pozar's reciprocity metho
