Double-sided MICs and their applications

Abstract-In this paper, a novel planar array antenna for multi-band linear polarization discrimination is proposed. The proposed array antenna consists of 12 patch elements and a double-balanced multiplier. A slot-ring and four diodes used in the multiplier also act as an antenna and amplitude detector, respectively. Furthermore, slot lines which are parts of feeding circuits also act as slot antennas. The Both-sided MIC technology is effectively employed to realize the feeding circuit which eliminates the extra impedance matching circuit. The array antenna is realized in a very simple and compact structure as all the antenna elements, feeding circuit and the multiplier/amplitude detector are arranged on both sides of a substrate. The proposed array antenna can discriminate ±45 • linear polarization in three frequency bands. The ability of the proposed array antenna to discriminate orthogonal linear polarization is successfully confirmed in C and X band by the experimental investigation.

Abstract-This paper proposes a novel planar direction-of-arrival (DOA) estimation antenna. The estimation capability of phase monopulse DOA estimation antennas is enhanced by integrating an RF multiplier that detects the phase relation between the sum and difference of the two received signals.The proposed antenna provides a wide range of estimation whereas the conventional monopulse DOA estimation antennas determine the angles of half space. A prototype antenna has been fabricated, and the proposed concept was successfully confirmed.

Abstract-In this paper, a technical concept and design of circular polarization detection patch array antenna using a double-balanced RF multiplier is proposed. The microwave integration technology is effectively employed to realize the proposed array antenna. The double-balanced RF multiplier is integrated with an orthogonal planar array antenna. The array antenna which consists of 12 patch elements and the RF multiplier is realized by embedding four zero bias Schottky barrier diodes on a slot-ring. The Both-sided MIC technology is successfully employed to realize the array antenna. The array antenna is realized in a very simple and compact structure as all the antenna elements, feeding circuit and the RF multiplier are integrated on both sides of a dielectric substrate. The ability of the proposed array antenna to detect the orthogonal circular polarization (LHCP and RHCP) is successfully confirmed by the experimental investigation.
