In [12], dual-band circularly polarized annular slot antenna is obtained by employing two square slots, a bended microstrip line and a cavity back. As shown in Figure 2(a), antenna 1 is a fold annular slot antenna , and the asymmetric of the slot width will lead to two split orthogonal degenerate modes around 2.

Jan 23, 1973 · SINGLE SLOT CAVITY ANTENNA ASSEMBLY . United States Patent 3713162 . Abstract: A thin flexible wrap-around antenna assembly, particularly suitable for use in conjunction with a propelled vehicle such as a missile, is disclosed and generally includes a first or inner cylindrical thin conductor that can be flush-mounted on the skin of the Antennas: Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters. US3810183A - Dual slot antenna device - Google Patents A dual slot antenna assembly is disclosed herein and generally includes a pair of concentrically positioned and radially spaced cylindrical conductors defining a pair of circumferential slots which are longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna device. An electrical signal feed assembly is connected with the conductors for exciting the Development of Microstrip Patch Antenna Design for S-Band Microstrip patch antenna used to send onboard parameters of article to the ground while under operating conditions. The aim of the paper is to design as tacked nearly square microstrip patch antenna design for S band 2 GHz to 4 GHz and study the effect of antenna dimensions Length (L), and substrate parameters relative Dielectric constant (ε r), substrate thickness (h) on the radiation

A dual slot antenna assembly is disclosed herein and generally includes a pair of concentrically positioned and radially spaced cylindrical conductors defining a pair of circumferential slots which are longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna device.

The slot/strip loop antenna is fed by a single straight microstrip line. It is demonstrated that the cavity-backed slot/strip loop antenna can achieve an axial ratio (d3 dB) bandwidth of 20% with good impedance matching. I. INTRODUCTION Cavity-backed slot antennas have two major advantages over cavity-backed wire Single & Double Diamond Circular Microstrip Patch Antenna size antenna. Fig. 3 :- Return loss of single diamond circular microstrip patch antenna Fig.3 shows that the antenna resonates at 1.88 GHz with return loss of -17.16 dB. This design can be used in IEEE ...
