This article demonstrates the coplanar waveguide (CPW) feed L- slot microstrip antenna for multi frequency band operation is presented. The proposed antenna is excited by a single CPW feed connected to a Microstrip antenna. In this radiating patch and feed are etched on the same dielectric material. A SMA connector is used to connect the feed strip which couples the energy to a radiating patch by capacitive feed. The length and width are designed to obtained dual band frequency range. A truncation is used for multiband operations and for proper impedance matching. L- slot is used to increase the depth of S11 parameter.

In this paper, a miniaturized ultra-wideband antipodal tapered slot antenna with exponential strip arms is presented. Two exponential arms with designed equations are optimized to reduce the lower edge cut-off frequency of the impedance bandwidth from 1480 MHz to 720 MHz, resulting in antenna miniaturization by 51%. This approach also improves antenna bandwidth without compromising the radiation characteristics. The dimension of the proposed antenna structure including the feeding line and transition is 158 × 125 × 1 mm3. The results show that a peak gain more than 1 dBi is achieved all over the impedance bandwidth (0.72–17 GHz), which is an improvement to what have been reported for antipodal tapered slot and Vivaldi antennas with similar size.

The airborne omni-directional antenna must not only satisfy the indicators of omni-directional horizontal requirements, but also have conformal shape with the surface of airplane. The common monopole antenna and microstrip antenna can not meet the above requirements. Under the background of the airborne antenna miniaturization and conformal demand, this article designs a kind of airborne circular slot antenna. The structure of the antenna is simple, which meets pattern VSWR < 1.4 bandwidth of 350 MHz to 376 MHz and meets pattern VSWR < 2 bandwidth of 338 MHz to 438 MHz .Its maximum gain within the operating frequency range can be 4.205 dB .
